TROUBLESHOOTING
SYMPTOM ACTION
Pilot will not light after
pressing the sparker many
times.
1. When lighting the appliance for the first time after installation or after
servicing, there is air in the gas line. It takes a while for all of the air to
purge out of the pilot before gas can reach the pilot and ignite.
Remove the glass door and try lighting the pilot many times to purge
the air.
2. Check to make sure the gas supply to the appliance is turned on and
there is adequate gas supply pressure to the appliance.
3. Check for sparks between the spark electrode and the pilot head when
the sparker is pressed. If there are no sparks:
a. Check for broken or poor connection from the sparker to the
electrode.
b. Check for the spark shorting or arcing at other locations.
c. Check for defective sparker.
d. Check for defective spark electrode.
4. With the door removed, try lighting the pilot with a match.
a. If air is blowing on the flame of the match, hold the control knob in
at the ‘ PILOT ’ setting until all the air is purged out of the line.
b. 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 may be defective.
Pilot will not remain on after
being lit.
1. Press the control knob all the way in (at the “ pilot ” indicator).
2. Hold the control knob in for a longer period of time.
3. If you are trying to re - light the pilot immediately after you have shut - off
the pilot, you have to wait 5 minutes for the valve to reset. (safety
system built into the valve)
4. 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, or a wrong
size pilot orifice.
5. Check for poor connection of the thermocouple to the valve.
6. Check for proper millivolts of the thermocouple. The thermocouple
should generate at least 20 mV or it is defective.
7. Check for defective gas valve.
The main burner does not turn
on with the pilot lit.
1. Check to make sure the control knob is turned to the ‘ ON ’ position.
2. Allow enough time for the pilot to heat up the thermopile to generate
sufficient voltage to activate the valve.
Please check to make sure the instructions are followed exactly before attempting
troubleshooting of the appliance.
WARNING: Troubleshooting and servicing of gas and electrical devices of the
appliance should only be conducted by a qualified service technician.
