    Electric motor overload reset buttons - how to find and reset motor overload switches

    An electric motor used in lots of equipment may include overload reset button on the motor body. If the motor is overloaded or if it overheats, this button will pop "out" indicating that an internal electric safety device has tripped,shutting the motor off.

    Once the motor has cooled sufficiently it can be re-started, usually by pushing the popped-out reset switch back down.

    If the motor turns off again on re-set you should not keep running it as it may be damaged and the system may be unsafe.

    The page top photo was taken of of an oil burner electric motor not an air conditioning blower fan motor or pump motor, but you'll see that all of these electric motors look a lot alike. Sometimes the reset button on an electric motor is hard to find, and sometimes there is no reset button!. But this photo shows the red reset button most clearly.

    Tips for Finding the Motor Reset Button

    Find the electric motor that operates the device that has been shut down. For example on a warm air heating system or central air conditioning system look in the air handler/blower compartment.

    On the blower motor itself, look for a red or yellow button which is normally flat with the motor surface but which will pop up to show that the motor has been shut off by its internal overload protection circuit.

    If the installer rotated the motor so that the button is facing away from you and impossible to see, feel around on the bottom and back side of the motor for the button's presence. Especially if the motor's internal protection has tripped, it should be easy to feel the button since it'll be sticking up about 1/2".

    When and How to Reset the Electric Motor on a Heating Blower, Air Conditioner Blower, or Water Pump

    When the air conditioner fan or blower motor has cooled sufficiently this button can usually be simply pressed back down to "reset" the switch. If the motor overload switch won't reset (stay depressed) either the motor is still too hot (wait) or there is another failure that needs diagnosis.

    Sometimes the reset button is present but hard to find, depending on the position in which the motor was bolted in place.

    What the Reset Button Looks Like When it has Not Tripped

    You can see that in this picture the button is flush with the motor surface. Sometimes these buttons are hard to find but they are usually present on heating and air conditioning system electric motors for fans and blowers.

    Electric Motors Using an Automatic Thermal Reset Switch - no reset button found

    While manual-reset thermal-overload switches are most common on heating systems such as oil burners and some fan motors, air conditioner electric motors and compressor motors and submersible well pump motors are an example of motor designs that may be use a thermal overload switch that resets itself automatically when the motor has overheated.

    Electric Motor Thermal Overload Switch Trip Temperatures
    Class A electric motor 140oC / 284oF
    Class B electric motor 165oC / 329oF

    Notes to the table above

    The reset temperature is not precisely specified but the automatic thermal overload switch will reset after the motor cools down. [1]

    If a well pump motor is overheating for any reason (low voltage, bad start/run capacitor, damaged motor, damaged pump impeller parts, loss of water in the well, pump running dry) it may be a model that will turn itself off when too hot. A thermal sensor inside the pump motor housing handles this job.

    With the motor off for a cool-down period, the thermal sensor automatically resets and the pump will run again. Typically the "off" time is 15-20 minutes. If the pump on-off activity is erratic or very long, it could be that the problem is a bad thermal sensor switch.

    Note that other electric motors may have a thermal reset switch that is mechanical and "pops out" to show a red "reset button" that must be pushed back in manually. If the motor is still too hot, pushing the button won't work - the button won't stay in.

    Electric Motor Reset Switch Troubleshooting Guide

    This first table is for electric motors use in air conditioners, air handlers, blower units, oil burners on boilers, steam boilers, water heaters etc. - HVAC equipment in general. A second section of defects (below) addresses oil burner motors.

    Table of Causes of Electric Motor Thermal Overload Switch-Off

    Things to Check if an Electric Motor Starts but Overheats and Trips its Reset Button
    Bad line voltage Use a VOM to check the voltage level at the pressure control switch

    If voltage is too low, check voltage at the electrical panel and check that the proper size wiring was used for the ampacity and length of run and that there are no partial shorts or damaged wires or connectors

    VOLTS MEASUREMENT METHODS
    Incorrect motor wiring Check the actual electrical wiring against the motor wiring diagram or the installation manual for the equipment Reconnect wiring properly
    Motor is too hot due to surroundings - inadequate ventilation

    Check the air temperature where the motor is located.

    If the air temperature is over 100 degF, the pump may be too hot and its thermal overload switch tripping because of the environment, not a pump problem.

    		Install adequate ventilation, or if needed, shading, or relocate the motor/equipment to a cool location
    Motor subjected to repeated overloading, overheating

    A motor subjected to overloading due to very long duty on-cycles may run hot and trip the thermal overload protection device.

    Eventually the thermal overload switch may itself fail and the motor will no longer restart nor can you reset the thermal overload switch.

    Check the recommended duty cycle and loading on your motor;

    check also for abnormally low voltage levels in the electrical supply.

    If necessary, replace the motor with a heavier-duty unit.
    Motor for a water pump operates too long at low water pressure If the well recovery rate is too poor and the pump is operating at low water pressure, possibly because a tailpiece is installed to prevent air injection and pump burnup, the pump may be overheating.

    Install a valve on the water discharge line and reduce water flow to increase water pressure inside the pump itself.

    Table of Causes of Oil Burner Thermal Overload Switch-Off
    Bad oil pump (fuel unit) Oil pump has seized or is binding, overloading the electric motor Disconnect the coupling between fuel unit and electric motor and manually turn each shaft to inspect for binding or seizure. Replace a bad fuel unit.
    Misaligned components Connections between the electric motor drive shaft, coupling, and driven parts are loose or improperly mounted

    Check for misalignment due to loose mounting bolts of motor, blower, fuel unit;

    check for improper seating of the motor against the oil burner housing such that the motor is askew. Re-mount.

    Bad electric motor start switch The electric motor will overheat if the start-switch does not disconnect at the proper or "throwout" rpm. See Electric motor start switch operation
    Jammed blower wheel If the oil burner air blower wheel has jammed, possibly due to debris, mechanical damage, obstruction, the motor may spin the coupling or may not rotate at all, overheating & shutting down Inspect the blower assembly for obstruction, free spinning, and repair
    Undersized electric motor Load requirements exceed the motor horsepower Hp nameplate ratings. [Unlikely on factory-assembled heating or air conditioning system but possible if someone performing a repair substituted a lower Hp motor].

    Using an Amp probe ammeter check the current draw of the motor against its nameplate rating.

    If the actual current draw when the motor is running exceeds the rated run-amps by more than 10% and if there is no binding or misalignment in the system we suspect that the motor is under-sized.

    See TEST EQUIPMENT, ELECTRICAL GUIDE - separate article
    Bad coupling Jammed or defective coupling between motor and driven components; improper belt tensioning on belt-driven components

    Usually a bad coupling inside the oil burner will fail by becoming loose and just spinning, so the motor runs but the driven components do not spin or spin at a too-low speed.

    But a bent, damaged, or jammed coupling might overheat a motor - OPINION - Ed.

    Electric Motor Lubrication Failure If the electric motor is a model that requires periodic lubrication and is not properly maintained its drive shaft or bearings may run dry, causing binding and overheating.

    Inspect the motor to determine if it is a model that requires lubrication.

    Check its maintenance history; check for shaft binding; lubricate the motor if appropriate; check motor drive shaft and bearings for excessive side play, wear, or looseness.

    Watch out: do not try to lubricate an electric motor that does not have lubrication fittings.

    Reply: steps in replacing a thermal overload switch in a small electric motor

    Bird

    Small electric motor thermal overload reset switch bypass, external switch or replacement

    First off is to avoid getting shocked or killed, so never work on equipment with power-on.

    At this website you can see DMMs VOMs SAFE USE OF inspectapedia.com/electric/DMM_VOM_Safety.php

    Keep in mind that when you’re not trained you don’t even know what you don’t know. A mistake can be fatal.

    Second is to avoid starting a fire by mis-wiring or by installing improper parts that don’t provide the overheat and over-current protection that your motor manufacturer (Marathon) decided this motor requires for safe operation.

    The therma/loverload switch on an electric motor is protecting against fire and shock, and protects both the motor and the circuit wiring from damage. It’s an important safety device as I will elaborate.

    Bird ate the thermal overload switch for this reader's electric motor (C) InspectApedia.com Bird

    My birds ate the thermal overload switch that’s why I had to get a new one the search protector is what is tripping not to switch

    I was able to order another thermal overload switch and I paid a lot of money to have it overnighted but it keeps tripping

    Common Causes of Thermal Overload Switch Tripping or Nuisance Tripping

    AO Smith electric motor overload switch at InspectApedia.comThermo swtiches or OL or overload switches are not what usually fail in an electric motor. Millions of them have been in use for decades. More often the problem is elsewhere.

    Therefore I wouldn't assume that the problem is the overload button or switch since the problem could equally or even more-likely be the motor itself -

    Illustration: a typical AO Smith electric motor thermal overload relay switch replacement part available from the manufacturer and from electrial suppliers.

    • a failed bearing or failing winding causing high current draw, overheating, tripping off
    • insufficient voltage to the motor
    • improper wiring to the motor (undersized)
    • improper motor selection for the environment (too hot)
    • improper motor selection for the application (motor is mechanically overloaded or taxed beyond its design)
    • improper motor usage: motor left running much longer than the manufacturer’s duty cycle, leading to overhating, or motor being constantly or too-frequently switched on and off, such as a well pump motor short cycling (often due to a waterlogged pressure tank)
    • improper motor maintenance: failure to lubricate bearings, clogging of ventilation ports with oily dust, sawdust, debris, exposure of the motor to water or leaks or flooding or corrosive environments, even mice or insects (getting into the motor)

    Electric Motor Thermal Overload Diagnostic #1:

    Even before looking at the motor itself a technician would confirm that the right voltage is being delivered and that the circuit wires are all properly sized for the current rating of the circuit, the motor, and the circuit breaker or fuse. Under-sized wires or low voltage can cause circuit or motor overheating and overload tripping.

    Electric Motor Thermal Overload Diagnostic #2:

    Inspet the motor for debris clogging the motor's air vent openings. Cleaning these and the motor may fix a thermal overload tripping problem.

    Electric Motor Thermal Overload Diagnostic #3:

    When the motor has cooled down you can't reset the button then the problem could be the switch itself. Try turning power off and letting the motor cool to room temperature, then see if the switch will re-set.

    Electric Motor Thermal Overload Diagnostic #4:

    With power off and the motor disconnected from whatever the motor drives, does the motor shaft spin easily? If not the bearings may be shot or the stator/commutator binding - the motor is shot or at the very least would need to be rebuilt.

    (For a typical 1 - 1/2 hp conventional electric motor a motor repair shop can do that but compare the repair price against the cost of a new motor).

    Electric Motor Thermal Overload Diagnostic #5:

    Even if the motor spins easily, is there any end play or wobble if you try to wiggle the motor's output shaft side to side? If so the bearing is probably shot - same as above.

    Electric Motor Thermal Overload Diagnostic #6:

    An electrician or technician trained in motor repair might remove the temperature/overload sensor switch and jump its switched wires together, then connect the motor to power.

    Then she might measure the current draw and confirm that the proper voltage is being delivered. If the motor runs she would then order the proper OEM repalcement sensor switch/relay.

    In other words, don’t buy a repalcement switch to stick into a bad motor: you’re thowing good money after bad and you’re doing something dangerous.

    External motor overload switches - OL switches do not include thermal protection

    There are external overload switches that can be wired into a motor circuit.

    That switch would monitor current draw (amps) and properly sized for the motor’s specifications it could turn off the motor if the current draw is excessive - as can happen with a bad bearing or motor overloading.

    Use the OEM Thermal Overload Switch

    Yeah, you could simply find the switch inside the motor, remove it, tie together the wires that it disconnects to turn off the motor, and the motor might “run” but it would be unsafe.

    Watch out: however when the motor manufacturer put in a *thermal* overload protection device their engineers decided that the motor needed protection not just from a current overload but from overheating. If you install an external switch it will not provide that safety feature - you’re risking a motor fire, electrical short, electrical arc explosion inside the motor, or a building fire.

    Basic Steps To Remove & Replace an Existing Overload Switch in a Small Electric Motor

    Normally the small electric motor overload switch will look much like the replacement switch (often sold grossly over-priced) I’ll show with these comments.

    Get the right OEM overload switch for your motor. On your Marathon 1 1/2 hp general purpose electric motor’s data tag there may be thermal protection switch specifications or data. Your motor includes: Thermally Protected, C0074820 051011 - those may be the OL specs but I’m not ssure - you’d need to confirm that with Marathon or with your electrial supplier.

    Your motor’s OL probably looks much like the AO Smith OL switch photo I’ll attach, but of course it could differ. In other appliances and motors OL switches look quite different. For example in a dishwasher the OL may be a white plastic strip with two wires connected to it.

    By removing the motor’s end-cap - the end opposite the motor’s output drive shaft you’ll see several internal parts including an overload switch that will look much like our example below.

    When you have the proper thermal/overload protection switch replacement part - MATCHING the specifications set by the manufacturer for your specific motor - it will usually wire up with the same wire color codes as the existing switch.

    The technician trained to do this job would locate the original switch, note its wire connections by switch terminal ID and color code, and match the new switch to the old one’s connections.

    Watch out: before touching anything in the motor

    • electrical power is off
    • electrical wires to the motor are removed
    • the motor is removed from its mount on the equipment it serves
    • the motor’s end cap cover is removed (don’t think this is always trivial)
    • the motor capacitor(s) will have been discharged to avoid getting a nasty shock

    Watch out: even this step is very dangerous. Discharging a capacitor by shorting its terminals using an insulated screwdriver can on some occasions blow up the capacitor injuring anyone nearby.

    Continuing:

    • to remove and replace the overload switch you may have to remove the capacitor and you may have to remove a small
      circuit board or “terminal board” in the motor to expose the wires and their connections.

    Some de-soldering and soldering might be required but usually the wires connect with push-on spade connectors.

    You might need to re-use some connectors to install the replacement overload switch.

    • the OEM replacement switch connections are made to match those of the switch removed and the motor is re-assembled
    • the motor is bench tested as we described earlier before it’s returned to use.

    On 2020-08-13 by (mod) how to test an electric motor overload switch or thermal switch

    Broan 2 wire thermal overload switch test procedure at InspectApedia.com
    Alfred:

    Watch out: if you are not trained in safe electrical work and procedures you could be shocked or killed when working on electrical equipment. That warning said

    With the switch removed from the motor,

    Use a DMM or VOM to test the overload switch as follows:

    Set the DMM/VOM to OHMS and to the most-sensitive or 1 Ohm or Rx1 setting or switch position

    How to Test a 2-Wire Thermal Overload Switch:

    Connect the DMM/VOM leads to the two wires of the switch;

    Read the resistance on the ohms scale: you should see zero resistance or very close to 0 ohms.

    If the switch is showing 1 ohm or higher resistance it should be replaced.

    How to Test a 3-wire Thermal Overload Switch:

    Klixon 3-wire thermal overload test procedure at InspectApedia.com

    Some thermal overload switches such as used on pool pumps and 3 phase motors have three wires or connections. In a 3-terminal thermal overload switch, each heater is wired in series with one of the phase windings of the electric motor that it is protecting.

    If the disc overheats it snaps "open" thus opening the neutral wire to turn the motor off. Dual -voltatge electric motors typically can still use a single thermal overload device.

    In this case

    Connect the DMM/VOM leads first to terminals #1 & #2: resistance should be 0 or very close to 0 ohms.

    Then connect the DMM/VOM leads to terminals #2 & #3: resistance should be 0 or very close to 0 ohms.

    If either of these tests shows resistance more than 1 ohm of resistance, then replace the switch.

    A thermal overload protector or reset button might "wear out" but I suspect another problem lurking here. Repeated operation at low voltage can damage some electric motors.

    A service tech will often shotgun the diagnosis by simply replacing the starting capacitor to see what happens - that's inexpensive.

    An experienced service tech can check out the compressor motor itself, for example by measuring its current draw and comparing that to normal.

    On 2020-03-27 by Swoop

    We have a 2hp motor on an air compressor that was initially wired with too small of wires. There's something like 300' of wire between the breaker and the compressor. The compressor ran, but repeatedly tripped the thermal overload. After being used in this condition for a few weeks, with multiple resets, the electrician re-wired to 240v. Recently, the compressor started tripping the thermal overload on the motor on a regular basis. When first put in service with the undersized wire, the red button was reset 5 or 10 times. In the last few months, maybe a few more times. Now it's tripping every few days. The compressor was run quite often the first month, but now only a few times a day for a few minutes. Do the thermal overload switches fully protect the motor? How probable is it that the first few weeks with the undersized wires damaged the motor? Do the red button, thermal overloads 'wear out'? Can an electrician determine if it's the motor or the thermal protection that needs replacement?

    Not necessarily, Robert; a broken winding may not open until at higher motor speed.

    On 2019-10-14 by Robert

    If it is a winding that opens would it react the same on both speeds?

    On 2019-10-14 - by (mod) -

    A winding that opens as the motor gets up to speed

    a failing motor bearing

    a bad internal centrifugal switch in the motor

    I have a 2 speed 1-1/2hp pump motor single phase 240 volt capacitator start capacitator run. It was tripping the breaker when starting. I thought it was the run capacitator and replaced it. Now it will tries to start but quits before it gets up to full speed. It no longer trips the breaker. What would be causing this?
    Thanks, I am an electrician but not a motor person. Hate to junk it but motor shops don't want to mess with this small of a motor.

    On 2019-09-27 - by (mod) -

    I can only guess but it sounds to me as if the motor is failing under load.

    On 2019-09-25 by Kenny

    My 3 hp air compressor electric motor starts and builds pressure to about 25 to 30 lbs and then the breaker trips on the motor, then about 15 to 20 secs it resets. I push the button on the breaker and it starts. Then the same thing happens again. What do you think maybe breaker or motor or something else? Thank You. Kenny

    Is there a reset button on a Hobart Dishwasher or how do you re-set the unit?

    An authoritative answer from Hobart was not easy to find, though you might get help from the manual for your Hobart dishwasher.

    I have not found a reset button.

    Most dishwasher controls re-set by turning the control dial through its operating positions back to OFF - open the door and then re-latch it.

    However a temperature sensor could be tripping off the dishwasher - try cleaning the sensor in the dishwasher - scrub with vinegar and a scrubby sponge - as that may fix the problem.
