Problem Possible Cause Remedy
No fuel oil.
Check fuel oil supply. Check that all hand operated all
fuel oil valves are in the open position. Fill oil storage
tank if necessary.
Clogged nozzle.
Replace nozzle with high quality replacement. Use
rating plate or Tables in Appendix A as a guide.
Clogged oil filter. Replace oil tank filter or in-line filter if used.
Low oil pump pressure.
Connect pressure gauge to oil pump. Adjust pump
pressure, or replace oil pump if necessary. Ensure that
erratic pressure readings are not caused by defective
fuel oil line.
Air getting into fuel oil
lines, or fuel oil line dirty,
clogged, or in some
manner defective.
Check fuel oil lines. Replace any compression fittings
found with high quality flared fittings. Check for any
signs of oil leaks. Any oil leak is a potential source of air
or contaminants.
Defective burner motor.
Check burner motor. If burner motor is cutting out on
over-load, determine why. Replace if necessary.
Water or contaminants in
oil.
Drain fuel oil storage tank, replace fuel oil. (Consult with
fuel oil supplier).
Furnace starts, but
cuts out requiring
manually resetting
the oil protector reset
button.
…continued
Frozen oil line.
Gently warm oil line. Insulate oil line. (Outdoor piping
size may require increased diameter).
Electrodes out of
adjustment or defective.
Check electrode settings. Check electrodes for dirt
build-up or cracks in porcelain.
Poor transformer high
voltage connections or
defective transformer.
Check contacts between transformer and electrodes. If
OK, replace transformer.
Fuel oil filter clogged.
Replace fuel oil storage tank filter and / or fuel oil in-line
filter.
Defective oil pump.
Check burner motor / fuel oil pump coupling. Check oil
pump pressure. Replace fuel oil pump if necessary.
Oil burner sputtering
at nozzle
Fuel oil line partially
clogged or contains air.
Bleed air from oil line. If problem persists, replace oil
line.
System temperature rise
too high.
System temperature rise should not exceed 85°F.
Check for clogged air filters. Check blower fan for
excess dirt build-up or debris. Speed up blower fan if
necessary.
Blower fan control out of
adjustment, (fan stops
too soon).
Check fan control settings. The fan control is adjusted
with a duct thermometer in the supply air plenum take-
off or first few inches of the supply air trunk duct. The "
fan off" setting should be 90° - 100°F. Once set, the
"fan on" setting is normally adjusted 10° - 30°F higher
than the "fan off" setting.
Fuel oil leak.
Check fuel oil line for leaks. Repair or replace if
necessary.
Excessive fuel oil
consumption.
Stack temperature too
high.
Check stack temperature. Stack temperatures will
normally range from 350° to 575°F. Check draft
regulator. Draft should be set to 0.02 in. w.c.
