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

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
