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.  Con-

tact your dealer to arrange a service call by a qualified service technician.

Symptom

Possible Causes

Corrective Action

1

.

After repeated triggering 

of the red or black piezo 

ignitor button, the spark 

ignitor will not light the 

pilot. Check for spark.

A

.

No gas or low gas pressure.

Check the remote shut-off valves from the appliance. Usually, there 

is a valve near the gas main. There can be more than one valve 

between the appliance and the main. 

B

.

No LP in tank.

Check the LP (propane) tank. You may be out of fuel.

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 

(spark at electrode).

Using match, light the pilot. If the pilot lights, turn off the pilot and 

trigger the piezo ignitor button again. If the pilot lights, an improper 

gas/air mixture caused the bad lighting and a longer purge period 

is recommended. If the pilot will not light, ensure the gap at the 

electrode and pilot is one-eighth inch to have a strong spark. If the 

gap is OK, replace the pilot.

2

.

The pilot will not stay lit 

after carefully following the 

lighting instructions.

A

.

Thermocouple.

Check that the pilot flame impinges on the thermocouple. Adjust the 

pilot for proper flame impingement.

Ensure that the thermocouple connection at the gas valve is fully 

inserted 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 

millivolt 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 5-7 in. w.c.  LP should be 11-14 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, there 

is no burner flame, the 

valve knob is in the ON 

position, and the ON/OFF 

switch is in the ON 

position.

A

.

On/off switch or wires 

defective.

Check the ON/OFF switch and wires for proper connections. Place 

the jumper wires across the terminals at the ON/OFF switch. If the 

burner comes on, replace the ON/OFF switch. If the switch is OK, 

place the jumper wires across the ON/OFF switch wires at the gas 

valve. If the burner comes on, the wires are faulty or connections are 

bad.

B

.

Thermopile may not be 

generating sufficient 

millivoltage.

Check that the pilot flame impinges thermopile properly.
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 

millivolts 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 

minimum.

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 

reading is below the minimum.
