15 Troubleshooting

With proper installation, operation, and maintenance your gas appliance will provide years of trouble-free service. If you do experience a problem, this troubleshooting guide will assist a qualified service technician in the diagnosis of a problem and the corrective action to be taken. This troubleshooting guide can only be used by a qualified service technician. Contact your dealer to arrange a service call by a qualified service technician.

	Symptom	Possible Causes	Corrective Action
1. After repeated triggering		A. No gas or low gas pressure.	Check the remote shut-off valves from the appliance. Usually, there

		C. Ignitor.	Check the spark at the electrode and pilot. If no spark and electrode
			wire is properly connected, replace the ignitor. Verify that there is no
			short in electrode wire.
		D. Pilot or misaligned electrode	Using match, light the pilot. If the pilot lights, turn off the pilot and

			trode and pilot is one-eighth in. to have a strong spark. If the gap is
			OK, replace the pilot.
2.	The pilot will not stay lit	A. Thermocouple.	Check that the pilot flame impinges on the thermocouple. Adjust the

	the lighting instructions.		Ensure that the thermocouple connection at the gas valve is fully in-
			serted and tight (hand tighten plus 1/4 turn).
			Verify proper voltage output from the thermocouple to the valve.
			Place one millivolt meter lead wire on the thermocouple copper lead.
			Place the second lead wire on the solder button on the back of the
			valve (blue wire). Start the pilot and hold the valve knob in. The mil-
			livolt reading should read 8-16 millivolts. If millivolt reading is less
			than 8 millivolts, replace thermocouple.
		B. Improper gas inlet pressure.	Natural gas should be 5-10 in. w.c. LP should be 11-13 in. w.c. Verify
			pressure with manometer.
		C. Valve.	If the thermocouple is producing 8-16 millivolts, replace control valve.
3.	The pilot is burning,	A. ON/OFF switch or wires.	Check the ON/OFF switch and wires for proper connections. Place

		erating sufficient millivoltage.	Be sure the wire connections from the thermopile at the gas valve
			terminals are tight and that the thermopile is fully inserted into the
			pilot bracket.
			Check the thermopile with a millivolt meter. Take the reading at TH-
			TP&TP terminals of the gas valve. The meter should read 350 mil-
			livolts minimum, while holding the valve knob depressed in the pilot
			position, with the pilot lit, and the ON/OFF switch in the OFF position.
			Replace the thermopile if the reading is below the specified mini-
			mum.
			With the pilot in the ON position, disconnect the thermopile leads
			from the valve. Take a reading at the thermopile leads. The reading
			should be 350 millivolts minimum. Replace the thermopile if the read-
			ing is below the minimum.
