Rheem furnace parts at InspectApedia.comHere, along with Rheeem, we include both Rheem and Ruud brands as well as Raypak (copper tube boilers for swimming pool heating and commercial hot water heating) together because in 1959 Rheem acquired the Ruud manufacturing company.

In 2010 we found it difficult to find Rheem and Ruud gas furnace installation manuals online, and found that Rheem's website does not offer easy email or telephone contact information for consumers.

Rheem / Ruud Contact Information

Quoting from the Rheem website this history helps understand who produces which brands of heating and cooling equipment:

Rheem upflow furnace at InspectApedia.com

Above: a Rheem up-flow furnace illustrating major parts in the heater.

Rheem is headquartered in Atlanta, Georgia. It manufactures in Fort Smith, Arkansas; Montgomery, Alabama; Oxnard, California; Acadia, Florida; and Eagan, Minnesota. All manufacturing facilities are ISO 9001 certified. Rheem operates a state-of-the-art Parts Distribution center in Randleman, NC and distribution facilities throughout the US and in Hamilton and Mississauga, Ontario, Canada.

Rheem also has an international presence in countries such as Australia, Canada, Mexico, Brazil and Singapore [and New Zealand - Ed.] . In 1987, Rheem became a wholly owned subsidiary of Paloma Industries of Nagoya, Japan, the world's largest producer of gas appliances.

In 1959, Rheem acquired Ruud Manufacturing Company, a pioneer in the water heating industry with a well-regarded product line and a distribution network throughout North America. In subsequent years, Rheem entered the heating and air conditioning market and expanded in the late 1960's and 1970's with the rapid growth of the central air conditioning industry.

In 1985, the company acquired Raypak, a leading producer of copper tube boilers used for swimming pool heating and commercial hot water supply and hydronic heating.

Rheem / Ruud HVAC Product Label Informationm

Rheem HVAC equipment like the indoor air handler or outdoor compressor-condenser unit is identified by a product data tag or sticker that contains information about the unit. The data tag will include two key identification fields: the product designation or identification code and the product's individual serial number.

Rheem / Ruud Product Designation Codes

The product designation or model identification code is a character string that provides information about the product type, features and capacity.

Rheem / Ruud Product Serial Number & equipment age

The product serial number is a unique character string including numbers that can be decoded to give the product's age and manufacturing details.

Rheem & Ruud HVAC Equipment Age Decoder

Ruud A/C compressor unit data tag (C) InspectApedia.com ThomasOn some Rheem or RUUD equpment the data tag includes the equipment's date of manufacture explicitly such as shown at the upper right of this RUUD air conditioner compressor/condenser unit data tag (cited below) where we see

MFD. 07/2007

Where the equipment's manufacture date is encoded we find the date of manufacture of Rheem or RUUD heating and cooling equipmet in at least five different formats depending on both when and by whom the equipment was actually manufactured, but in all cases we can find four numeric digits in the serial number that encode either

the year shown here as YY and week number shown here as WW

or the year shown as YY and month number shown as MM as seen in the following examples.

I need a 3-prong plug for my Rheem Electric Furnace

Thank you for all of this info, using the decoder, I still could not figure out the age of my furnace, but maybe it does not matter as long as I can find a right replacement part.

Here is the 16 digit serial number on my Rheem High Efficiency furnace: AG5D 307 F2990 4873

I am looking for a 3 prong plug replacement for this model RGDE-10NRA.JR and a diagram of the electrical box on the side of this furnace where the electrical cord attaches to.

Any help is greatly appreciated. Thank you On 2021-10-31 by Laura

by inspectapedia.com.moderator Instructions for Making the Electrical Connections for a Rheem Furnace

@Laura,

Is it possible that we're discussing an ordinary electrical connector ? If so, that should be available at any electrical supplier or hardware store?

If so, you'll find the plug described at

ELECTRICAL WALL PLUG WIRING ID & CONNECTIONS 

and you'll see that there are just three wires: Hot (black), Neutral (white) and Ground (green or bare wire).

At the furnace there will be matching hot and neutral connections identified in the IO manual fo your heater.

If you don't have the installation/operation/service manual for your Rheem furnace check for it at

RHEEM Gas Furnaces, boilers, heaters, also see Ruud

Here's what you'll find in your Rheem Furnace Manual under the section on how to make electrical connections for a Rheem RGR or RTT series furnace. Your IO manual will have similar instructions.

Connect from the electrical disconnect to the junction box on the left side of the furnace, inside the blower compartment. For the proper connection, refer to the appropriate wiring diagram located on the inside cover of the furnace control box and in these instructions.

NOTE: UPFLOW MODELS ONLY The electrical junction box may be moved to the right side if necessary. A knockout is provided. Seal the opposite hole with plug provided. NOTE: L1 (hot) and L2 (neutral) polarity must be observed when making field connections to the furnace.

The ignition control may not sense flame if L1 and L2 are reversed.

See Figure 43.

Make all electrical connections in accordance with the latest edition of the National Electrical Code ANSI/NFPA70 – or in Canada, the Canadian Electrical Code Part 1-CSA Standard C22.1 and local codes having jurisdiction.

These may be obtained from: National Fire Protection Association, Inc. Batterymarch Park Quincy, MA 02269 Canadian Standards Association 178 Rexdale Boulevard Rexdale, Ontario, Canada M9W 1R3

Old RUUD air conditioner condenser unit won't run: diagnostic tricks

I have a very old (>27 years) RUUD a/c with an emerson 1/3 HP 4-wire PSC motor. A few days ago I noticed the fan was not running outside. Fan would not spin easily with a stick with power on or off. Decided fan motor must be bad.

Took it out, still wired. Upside down, spun it easily by hand. Put circuit breaker back on; fan motor humming loudly; so decided motor OK, but start capacitor was bad. Got one next day and reassembled. No improvement.

Pulled fan motor out of cage again. Still wired, upside down on top of unit.

Now with power on, I COULD spin it up and it seemed to operate OK. Tried putting it back right way. Now, nothing. Checked circuit breaker again.

Two pole 60 amp Square D; one side open in either position (I remember replacing circuit breaker about 25 years ago).

Had to order, so another day gone. Got it yesterday. Now fan started itself when AC powered (but still upside down on top of unit), so I figured it was fixed with new capacitor.

Reassembled, fan now in correct position. Back to not starting itself, plus powered fan difficult to turn again, humming loudly. Started checking all wiring, turning fan over, etc. Managed to pull couple wires loose.

\(Previously, they didn't seem to match all the on-line help about how to wire.) Think I got all back where they had been when it was working in past, but not positive.

Long story shortened -- fan works way it should when it is upside down; sounds like it is fighting with itself when right side up.

What gives? Also, noticed a little up-down play in shaft, but none side to side. - On 2020-07-19 by elrod

Reply by (mod) - diagnostic steps lead to bad fan motor or bearings

Elrod

That's an interesting and helpful series of diagnostic steps you tried. I suspect that the fan bearings are shot, so when the motor is in proper position the shaft is binding.

Followup by Elrod

Thanks, I had two other opinions this morning that offered the same thoughts, because of the vertical play. Except one thought it was probably electrical (position relative to brushes) and not mechanical (binding) because the effect was worse when under power.

I might keep the motor and eventually do a post-mortem autopsy on it to find out for sure (but this is definitely low priority for the near future).

Either way, the consensus seems to be the motor has reached its EOL, being more expensive to rebuild than to replace.

Now, if I can just be successful in removing the STUCK fan blade from the shaft (even a gear puller didn't help, was just bending the fan flange our of flat -- I see more work ahead of me for that).

My appreciation for your taking the time. Maybe several of us learned from this. Stay safe.

Elrod,

That post mortem would be both interesting and helpful to others, so if you do it, please tell me what you find.

 

Where to find a wiring diagram for a Ruud UGDA-075C-ER ?

Need Ruud UGDA-075C-ER Wiring diagram On 2023-05-17 by Glenn J Dupree

Answer by InspectApedia Publisher

@Glenn J Dupree,

Sure

We give that wiring diagram above on this page

 

Here's the wiring diagram for an old Rheem Furnace that has no control board -

Thermostat & gas valve wiring for Rheem 3204 Gas Furnace (C) InspectApedia.com Childers

This one is so old there is no Control Board. I think I figured it out. Looks like a wire goes from the 24 Volt to a thermostat back to the black switch on the gas valve.

Watch out: Safety Warning by (mod) - RHEEM Model 3204-125HD Gas Fired Force Air Furnace gas valve & thermostat connections - warning: unsafe Honeywell V8243, V8280, V8292 gas valve on old Rheem Furnaces

RHEEM Model 3204-125HD Gas Fired Force Air Furnace gas valve thermostat connections (C) InspectApedia.com Childers

Thanks for that added detail. Above, excerpted from the wiring diagram on the Rheem 3204-125HD gas furnace, is the wiring diagram for the Honeywell V8243, V8280 & V8292 Gas Valve.

Thermostat & gas valve wiring for Rheem 3204 Gas Furnace (C) InspectApedia.com Childers

Watch out: The U.S. Federal Register / Vol. 48, N a 56 / Tuesday, March 22, 1983 / Notices pp. 11978 & surrounding report that many of the models of this gas valve was found to be unsafe.

Your heating system's safety relies, almost certainly on a basic feature built into the gas valve - perhaps a standing pilot and thermocouple that will prevent a signal from the thermostat from opening the valve if the pilot isn't lit.

Excerpts:

18. The design inadequacies affecting the stop mechanisms of these controls render them defective under section 15 of the CPSA, 15 U.S.C. 2064.

26. Should an ignition source be introduced to a volatile LP fuel/air mixture, an explosion and fire will occur.

These are very helpful photos, John, thank you. I'll keep them with this article series and probably add this discussion at a appropriate thermostat wiring instruction page - linking also back between this page and that.

Working together makes us smarter. Below: Installation instructions for similar gas valves for furnaces. See instructions for Honeywell and other gas valves at:

GAS BURNER & GAS VALVE CONTROLS - our library of gas burner & gas valve controls, installation & wiring Instructions where we repeat this discussion and expand it to include details about the safety hazards of the Honeywell V8243 / V8280 / V8292 control.

 

Where do the thermostat wire connect on an old Rheem 3204 Furnace?

I have a RHEEM Model 3204-125HD Gas Fired Force Air Furnace. Where does the wires for the Thermostat connect at?
It's a real old furnace that is going into my garage. - On 2022-09-14 by John Childers IA-Council Bluff -

Answer by (mod) - find the control board

There ought to be a control board in the furnace, perhaps in the blower compartment, onto which you'll see the thermostat wire terminals, usually marked "T" and "T"
