Possible Cause

Corrective Action

1. Pilot won’t light.

The ignitor/module

makes noise, but no

spark.

A. Incorrect wiring.

Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor are

connected to correct terminals on module and pilot assembly.

B. Loose connections or electrical

shorts in the wiring.

Verify no loose connections or electrical shorts in wiring from mod-

ule to pilot assembly. Verify connections underneath pilot assembly

are tight; also verify igniter and fl ame sense wires 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 right side of pilot hood. The gap should be

approximately .17 in. or 1/8 in. (3 mm).

2. Pilot won’t light,

there is no noise or

spark.

A. No power, transformer installed

incorrectly, or depleted batteries.

Verify that transformer is installed and plugged into module. Check

voltage of transformer at connection to module. Acceptable read-

ings of a good transformer are between 6.4 and 6.6 volts AC. Bat-

tery power supply voltage must be at least 4 volts. If below 4 volts,

replace batteries.

B. A shorted or loose connection in

wiring confi guration or wiring har-

D. Module not grounded.

Verify black ground wire from module wire harness is grounded to

metal chassis of appliance.

3. Pilot sparks, but

Pilot will not light.

A. Gas supply.

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

pressure reading is within acceptable limits.

B. Ignitor gap is too large.

Verify gap of igniter to right side of pilot hood. The gap should be

approximately .17 in. or 1/8 in. (3 mm).

C. Module is not grounded.

Verify module is securely grounded to metal chassis of appliance.

D. Pilot valve solenoid

Verify that 1.5 to 1.8 VDC is supplied to pilot solenoid from module.
