Troubleshooting
Please check to make sure the instructions are followed exactly before attempting trouble shooting of the appliance.
WARNING:
Trouble shooting and servicing of gas and electrical devices of the appliance should only be conducted by a
qualified service technician.
CAUTION:
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after servicing.
PROBLEM
POSSIBLE CAUSE
CORRECTIVE ACTION
Pilot will not
light after
pressing the
sparker many
times.
Air in gas line.
No gas supply.
Piezo wire loose.
Electrode grounding.
Piezo wire grounding.
Defective Piezo.
Electrode gap Incorrect.
Purge air out of gas line.
Check to make sure the gas supply to the appliance is turned on and
there is adequate gas supply pressure to the appliance.
Check for sparks between the spark electrode and the pilot head when
the sparker is pressed. If there are no sparks:
Check for broken or poor connection from the sparker to the electrode.
Check for the spark shorting or arcing at other locations.
Check for defective piezo.
Check for defective/cracked spark electrode.
With the viewing door open, try lighting the pilot with a match.
Note: If there is no gas or air coming out of the pilot and there is gas
pressure to the appliance, the pilot orifice may be blocked or the gas
valve maybe defective.
Pilot will not
remain on
after being lit.
Poor Pilot flame.
Faulty thermocouple.
Thermocouple and/or
Thermopile grounding.
Loose TP-THTP on gas valve.
Faulty gas valve.
Note: This is very rare and
faults blamed on the gas
valve are usually incorrect.
Check to see if the pilot flame is large enough to reach and surround the
thermocouple. If the flame is too small, check for correct gas supply
pressure. If pressure is good, adjust the pilot flame size with the
adjustment screw on the valve. If the flame cannot be adjusted, there
might be some debris obstructing the pilot orifice.
Check for correct millivolts at the thermocouple. The thermocouple
should generate at least 30 mv.
Check for poor connection of the thermocouple and thermopile to the
valve.
If readings are correct for thermopile and thermocouple replace gas
valve.
Frequent pilot
outage
problems.
Pilot adjusted too low.
Switch wires may be
grounding out.
Thermocouple worn.
Adverse wind conditions.
Adjust pilot and clean if required.
Check switch wires.
Check thermocouple millivolts (see above).
Check termination location is not subject to adverse environmental
conditions.
Sharp blue
flames lifting
off burner.
Incorrect aeration adjustment.
Reduce primary aeration adjustment.
Convection
blower does
not operate.
No power supply.
Thermal snap switch lose or
defective.
Loose electrical connection.
Defective speed controller.
Defective blower.
Check electrical supply to unit.
Turn the fan speed control to a different setting, make sure it is not in
the off position
Check for correct positioning of the snap disc. You can by-pass the
snap disc to check it’s operation.
Check all electrical connections are secure.
By-pass the speed controller to check for defective operation.
With the speed control by-passed check for 120 VAC to the motor. If
you have 120VAC and the motor is not working, the blower motor is
defective.
