10 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 person 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.

Reversed wires at the module may cause system to make sparking

 

 

noise, but spark may not be present at pilot hood.

 

 

 

 

b. Loose connections or electrical

shorts in the wiring.

ule to pilot assembly. Rod closest to pilot hood should be ignitor.

 

 

Verify connections underneath pilot assembly are tight; also verify

 

 

connections are not grounding out to metal chassis, pilot burner,

 

 

pilot enclosure, mesh screen if present, or any other metal object.

 

 

 

 

c. Ignitor gap is too large.

Verify gap of igniter to pilot hood. The gap should be approximately

 

 

.17 inch or 1/8 inch.

 

 

 

 

d. Faulty module.

Turn ON/OFF rocker switch or wall switch to OFF position. Remove

 

 

ignitor wire “I” from module. Place ON/OFF Rocker switch or wall

 

 

switch in ON position. Hold ground wire about 3/16 inch away from

 

 

“I” terminal on module. If there is no spark at “I” terminal module

 

 

must be replaced. If there is a spark at “I” terminal, module is fine.

 

 

Inspect pilot assembly for shorted sparker wire or cracked insulator

 

 

around electrode.

 

 

 

2. Pilot won’t light,

a. Transformer installed correctly.

Verify that transformer is installed and plugged into module. Check

ing configuration or wiring harness.

Verify there is a tight fit. Verify pilot assembly wiring to module.

 

 

Remove and verify continuity of each wire in wiring harness.

 

 

 

 

c. Improper wall switch wiring.

Verify that 110/VAC power is “ON” to junction box.

 

 

 

 

d. Module not grounded.

Verify black ground wire from module wire harness is grounded to

 

 

metal chassis of appliance.

 

 

 

 

e. Faulty module.

Turn ON/OFF rocker switch or wall switch to OFF position. Remove

 

 

ignitor wire “I” from module. Place ON/OFF Rocker switch or wall

 

 

switch in ON position. Hold ground wire about 3/16 inch away from

 

 

“I” terminal on module. If there is no spark at “I” terminal module

 

 

must be replaced. If there is a spark at “I” terminal, module is fine.

 

 

Inspect pilot assembly for shorted sparker wire or cracked insulator

 

 

around electrode.

flame lifts from pilot hood, the circuit is broken. A wrong orifice or

 

 

too high an inlet pressure can cause pilot flame to lift. The sensor

 

 

rod may be contaminated. Clean sensor rod with emery cloth.
