TROUBLESHOOTING SUGGESTIONS
OIL BURNER
1. BURNER FAILS TO START:
A. Defective on/off or fuel transfer switch.
Replace switch.
B. Control circuit has an open control contact.
Check limits, low water cutoff, proof of closure
switch and others as applicable.
C. Bad fuse or switch open on incoming power
source. Correct as required.
D. Motor overloads tripped. Reset and correct
cause for trip out.
E. Flame safeguard control safety switch
tripped out. Reset and determine cause of
apparent flame failure.
F. Loose connections or faulty wiring. Tighten
all terminal screws and consult wiring diagram
furnished with the burner.
G. Frozen oil pump shaft preventing blower
motor operation. Replace oil pump.
H. Flame safeguard control starting circuit
blocked due to flame relay being energized.
Possible defective scanner or photocell -
replace. Possible defective amplifier - replace.
Scanner actually sighting flame due to leaking
fuel valve - correct unwanted flame cause.
Defective flame safeguard control - replace.
I.
Defective blower motor. Repair or replace.
2. OCCASIONAL LOCKOUTS FOR NO
APPARENT REASON:
A. Check for proper settings on direct spark oil
ignition electrodes. Make certain that gap is
not too wide and the “light-off” oil pressure is as
recommended.
B. Direct spark ignition. Verify that there are no
cracks in the porcelain and that transformer end
and electrode end plug-in connections are tight.
C. Loose or broken wires. Check all wire nut
connections and tighten all terminal screw
connections in panel and elsewhere as
appropriate.
D. Occasional low supply voltage. Contact local
utility to correct. Make certain the burner control
circuit transformer (if supplied) is correct for the
voltage and power (VAC) being supplied.
3. BURNER MOTOR RUNS, BUT DIRECT SPARK
IGNITED OIL FLAME IS NOT ESTABLISHED:
A. Defective or incorrect size oil nozzle.
Remove and clean or replace.
B. Low oil pressure. Check with gauge for correct
“light-off” pressure.
C. Defective oil pump. Replace.
D. Defective oil solenoid valve. Replace.
E. Oil pump coupling loose and defective.
Replace or tighten as required.
F. Low oil pressure switch (if supplied)
defective or incorrectly set. Adjust or replace
switch.
G. Ignition transformer defective. Replace.
H. Ignition electrode set incorrectly. Remove
electrodes and reset.
I.
Ignition electrodes cracked and grounding
out spark. Replace electrodes.
J. Ignition leadwire defective and grounding
out spark. Replace.
K. Ignition plug in connections at transformer
or electrode loose. Tighten.
L. Air flow switch not making circuit. Adjust set
point or replace.
M. Defective flame safeguard control or plug in
purge timer card. Replace.
N. Air dampers held in high fire position due to
mechanical binding of linkage. Readjust
linkage.
O. Loose wiring connections. Check and tighten
all connections.
