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.
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 30 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 gen-
erate 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.
