ohms set at lowest range.

 

 

 

 

e. Faulty module.

Turn ON/OFF rocker switch or wall switch to OFF posi-

 

 

tion. 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.

 

 

 

4. Pilot sparks, but Pilot

a. Correct gas supply.

Verify that incoming gas line ball valve is “open”. Verify that

will not light.

 

inlet pressure reading is within acceptable limits, inlet pres-

 

 

sure must not exceed 14 in. W.C.

 

 

 

 

b. Ignitor gap is too large.

Verify that spark gap from ignitor to pilot hood is .17 in. or

 

 

1/8 in.

 

 

 

 

c. Module is not grounded.

Verify module is securely grounded to metal chassis of

 

 

appliance.

 

 

 

 

d. Module voltage output / Valve/Pilot

Verify battery voltage is at least 2.7 volts. Replace batteries

 

solenoid ohms readings.

if voltage is below 2.7.
