Troubleshooting (continued)

Symptom

Possible Cause

Corrective Action

4. Pilot lights but contin-

ues to spark, and main

burner will not ignite.

(If the pilot continues

to spark after the

pilot flame has been lit,

flame rectification has

not occurred.)

A. A shorted or loose connection in flame

sensing rod.

Verify all connections to wiring diagram in manual. Verify

connections underneath pilot assembly are tight. Verify

flame sense or igniter wires are not grounding out to metal

chassis, pilot burner, pilot enclosure or screen if present, or

any other metal object.

B. Poor flame rectification or contaminated

flame sensing rod.

With fixed glass assembly in place, verify that flame is en-

gulfing flame sensing rod on left side of pilot hood. Flame

sensing rod

should glow shortly after ignition. With a multi-

meter, verify that current in series between module and

sense lead is at least 0.14 microamps. Verify correct pilot

orifice is installed and gas inlet is set to pressure specifi-

cations. Polish flame sensing rod with fine steel wool to

remove any contaminants that may have accumulated on

flame sensing rod.

C. Module is not grounded.

Verify module is securely grounded to metal chassis of ap-

pliance. Verify that wire harness is firmly connected to the

module.

D. Damaged pilot assembly or contami-

nated flame sensing rod.

Verify that ceramic insulator around the flame sensing rod

is not cracked, damaged, or loose. Verify connection from

flame sensing rod to white sensor wire. Polish flame sens-

ing rod with fine steel wool to remove any contaminants

that may have accumulated on flame sensing rod. Verify

continuity with a multi-meter with ohms set at lowest range.

Replace pilot if any damage is detected.

E. 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. If there is no spark at “I”

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

terminal, module is fine.
