How to disassemble basic oil burner parts:

To diagnose and repair the most-common oil burner operating problems some disassembly is often required.

Watch out: oil burner service and repair, to be both safe and effective, requires training and special equipment. A homeowner can not properly adjust the oil burner combustion air, pressure, nor other features. However, understanding basic and commonly cleaned or replaced oil burner parts such as the nozzle, nozzle adapter, electrodes, turbulator, can help diagnose and fix oil burner trouble.

This article series explains how to inspect, diagnose & repair oil burners used on oil-fired heating boilers or furnaces using a visual inspection approach as well as (optional) simple test equipment.

We include a description of common oil burner adjustment and operating problems and we illustrate some of the basic oil burner tests and measurements made in servicing and adjusting the equipment for safe, efficient operation.

Signs of Trouble Inside the Oil Burner - Simple Disassembly, Inspection, Testing

Oil burner gun operation (C) D Friedman - Audel

We look for obvious trouble signs before making any changes or adjustments to the oil burner assembly by turning off power to the equipment, shutting off the oil supply line at the closest service valve, and opening the oil burner for inspection.

Most oil burners are opened by loosening two screw clamps at the front of the transformer box mounted atop the oil burner tube and folding the hinged transformer back to expose the interior of the tube, the oil burner nozzle assembly, and other parts.

Some obvious trouble signs inside the oil burner include the following

Oil Burner Won't Run: Diagnostic Steps - what to check in what order

This topic has moved. Now
at OIL BURNER WONT RUN we have collected oil burner diagnostic procedures from several texts, [1] - [22] adapted, expanded, and generally re-ordered steps in order of most likely to be successful and easiest to perform.

Readers needing an approach to heating system inspections that assures thoroughness, should also
see HEATING SYSTEM INSPECTION PROCEDURE where we explain an organized approach to inspecting the entire heating system, beginning outdoors, continuing indoors, and ultimately in most detail in the boiler or furnace room.

This article series explains the inspection, diagnosis, & repair of oil burners used in heating appliances such as hot water boilers, steam boilers, & water heaters.

An expert inspection of an oil burner begins either with having made note of building owner/occupant concerns (noises, odors, no heat, high fuel costs), or with having made some basic visual observations outside: a sooty chimney top, for example. The sketch is courtesy of Carson Dunlop Associates. )

The oil burner inspection continues indoors, even before entering the utility room where the oil burner (or often more than one of them if oil fuel is used for both heating and a separate water heater) is located: look at the building interior as you enter: are there odors, soot deposits, noises associated with the heating system?

The oil burner inspection becomes detailed, and diagnostic, when you can actually see the equipment. It's obvious that you should notice oil leaks, soot in the boiler or furnace room, noises, odors, signs of repeated repairs, piles of junked parts, signs of unprofessional work (covers off of controls, sloppy wiring or plumbing). But just what each of these clues might mean bears some additional explanation that we offer below.
