Possible Causes

Corrective Actions

1.

The ignitor/module makes

Reversed wires at the module may cause the system to make a sparking

B.

Loose connections or

Verify connections underneath pilot assembly are tight; also verify the

 

 

 

 

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

 

 

 

 

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

 

 

C.

Ignitor gap is too large.

Verify gap of ignitor to pilot hood. The gap should be approximately .17 in. or

 

 

 

 

1/8 in.

 

 

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 in. 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.
