Troubleshooting
Oil burners that are designed for use on road maintenance 
equipment are built to take temperature extremes, 
vibration, and rough handling. When performing the 
following troubleshooting steps, we assume that the oil 
burner motor and ignition transformer operate continuously 
and the oil solenoid valve, which controls oil fl ow, is cycled 
by the equipment controls. We also assume that there is 
power to the burner and fuel in the tank. 
In addition to typical mechanics tools, it is recommended 
to have the following equipment on hand.
Meter capable of measuring volts, ohms and amps,
ignition transformer tester,
smoke pump tester,
combustion analyzer, and
0 to 200 psi pressure gauge.
See Table 3 on following page for troubleshooting steps.




Clean the blower wheel, air inlet, air guide, retention 
head and static plate of any dirt, asphalt or other 
material.
Check motor current.  The amp draw should not 
exceed the nameplate rating.  Check all wiring for 
loose connections or damaged insulation.
Check the pump pressure and cutoff function.
Check primary control safety lockout timing if 
applicable.  Refer to the information supplied by the 
control manufacturer for procedures.
Check ignition system for proper operation.
Inspect the exhaust system for soot accumulation or 
other restriction.
Clean the equipment thoroughly according to the 
manufacturer’s recommendations.
Check the burner performance using test instruments.
It is good practice to make a record of the service 
performed and the combustion test results.
