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 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 (cracked ceramic).
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.
5. Check wiring and connections to spill switch.
Pilot will not remain on after being
lit. 1. Press the control knob all the way in.
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 a minute for the valve to reset.
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 proper millivolts of the thermocouple. The thermocouple should generate at
least 30 mV or it is defective.
6. 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.
