TROUBLE POSSIBLE CAUSE REMEDY
A. Electrodes out of alignment.
B. Electrodes insulator failure.
C. Water flow switch not closing.
D. Vacuum switch not closing.
E. Temperature control switch not closing.
F. Fuel solenoid valve not opening.
G. Weak transformer.
H. Faulty cad cell (if equipped).
I. Faulty promary control (if equipped).
J. Burner motor thermal protector locked out.
K. Wiring.
L. Burner switch.
M. Pump pressure.
N. Venting.
O. Sooting.
P. No fuel.
A. Clogged fuel filter.
B. Fuel leak.
C. Kinked or collapsed fuel line.
D. Low fuel pressure.
E. Faulty burner oil pump.
F. Air leak in intake lines.
G. Clogged burner nozzle.
A. Clogged fuel filter.
B. Clogged fuel pump filter screen.
C. Fuel oil too viscous.
D. Air leaks in intake lines.
E. Kinked or collapsed fuel line.
F. Burner shaft coupling slipping.
G. Fuel Nozzle worn.
H. Faulty oil pump.
A. Partially clogged fuel pump strainer or
filter.
B. Air leaking around fuel pump cover.
A. Improper fuel.
B. Air to burner insufficient
C. Fuel nozzle interior.
D. Water in fuel
E. Gun out of alignment.
A. Low voltage.
B. Fuel too viscous.
C. Fuel pump defective.
D. Motor defective.
A. Dirty or damaged electrodes.
B. Air adjustment open too far.
C. Poor fuel spray pattern.
D. Incorrect electrode setting.
E. Weak transformer.
A. High limit temp control reset tripped if so
equipped.
B. Burner motor reset button tipped.
A. See “ADJUSTING ELECTRODE ASSEMBLY” in BURNER MAINTENANCE
SECTION.
B. Remove and replace if there are breaks, cracks, or spark trails.
C. Adjust, repair, or replace switch.
D. Adjust, repair or replace switch.
E. Adjust or replace the TEMPERATURE CONTROL.
F. Clean, repair, or replace solenoid.
G. Clean and check transformer terminals. Check transformer for spark per
“TRANSFORMER TEST” in BURNER MAINTENANCE SECTION.
H. Clean and test cad cell, replace if required.
I. Replace primary control.
J. See “Burner motor thermal protector locked out.
K. All wire contacts are to be clean and tight. Wire should not be cracked or
frayed.
L. Test switch operation. Remove and replace as necessary.
M. See “Low fuel pressure”.
N. A downdraft will cause delayed ignition. Soot deposits on the coil and burner
can interrupt air flow, and cause shorting of the electrodes. Clean as
required.
O. Soot deposits on the coil and burner can interrupt air flow, and cause shorting
of the electrodes. Clean as required.
P. See “No fuel.”
A. Remove and replace filter per FUEL FILTER SECTION.
B. Repair as necessary.
C. Remove and replace fuel line.
D. See “Low frel pressure”.
E. Adjust pressure or replace.
F. Tighten all fittings.
G. Remove and relace (Do not clean).
A. Remove and replace filter per FUEL FILTER page.
B. Remove pump cover and clean strainer using a brush and clean fuel oil, diesel
oil or kerosene.
C. Operate a lighter oil or in warmer area.
D. Tighten all fittings.
E. Remove and replace.
F. Remove and replace.
G. Remove and replace with specified nozzle on BURNER ASSEMBLY.
H. Remove and replace.
A. Remove and replace strainer per FUEL PUMP FILTER in OIL BURNER
MAINTNANCE Section.
B. Check fuel pump cover screws for tightness and damaged gasket.
A. Refuel with FUEL specified on MACHINE SPECIFICATIONS.
B. See AIR BAND ADJUSTMENT in OIL BURNER MAINTENANCE section.
C. Replace nozzle.
D. Inspect fuel filter for water presence.
E. Bend oil pipe to center burner nozzle.
A. Voltage must match those specified in the BURNER section of the manual
under MACHINE SPECIFICATIONS section.
B. Operate in warmer conditions or with fuel adapted to cold weather conditions.
C. Check that fuel pump turns freely.
D. Call service technician or take motor to repair/ warranty station.
A. Clean and replace.
B. Readjust per AIR BAND ADJUSTMENT in OIL BURNER MAINTENANCE
section.
C. Remove and replace with fuel nozzle specifies in BURNER ASSEMBLY.
D. Readjust per ADJUSTING ELECTRODE ASSEMBLY in OIL BURNER
MAINTENANCE.
E. See TRANSFORMER CHECK in OIL BURNER MAINTENANCE section.
A. Reset if necessary. CAUTION: Do not keep hitting the “reset button” if you
have oil pressure you are just filling the burner combustion chamber with oil
and if ignited will cause an explosion.
B. Reset if necessary.
