TROUBLESHOOTING

Please check to make sure the instructions are followed exactly before attempting trouble shooting of the appliance.

WARNING: Troubleshooting and servicing of gas and electrical devices of the appliance should only be conducted by a qualified service technician.

SYMPTOM		ACTION
Pilot will not light after	1.	When lighting the appliance for the first time after installation or after
pressing the sparker many		servicing, there is air in the gas line. It takes a while for all the air to

		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	1.	Press the control knob all the way in.
being lit.	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.
	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	1. Check to make sure the control knob is turned to the ‘ON’ position.
turn on with the pilot lit.	2.	Allow enough time for the pilot to heat up the thermopile to generate
		sufficient voltage to activate the valve.
