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.

A. Standing Pilot Ignition System

 

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

 

of the red or black piezo

 

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

 

ignitor button, the spark

 

tween the appliance and the main.

 

ignitor will not light the

 

 

 

B. No lp in tank.

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

 

pilot.

 

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

 

 

(spark at electrode).

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 elec-

 

 

 

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

 

after carefully following

 

pilot for proper flame impingement.

 

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 5-14 in. w.c. LP should be 10-14 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,

A. ON/OFF switch or wires.

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

 

there is no burner

 

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

 

flame, the valve knob is

 

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

 

in the ON position, and

 

is OK, place the jumper wires across the ON/OFF switch wires at the

 

the ON/OFF switch is in

 

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

 

the ON position.

 

are bad.

 

 

B. Thermopile may not be gen-

Check that the pilot flame impinges thermopile properly.

 

 

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.
