Symptom
Possible Cause
Corrective Action
Pilot sparks, but Pilot will not light.
Gas supply.
Verify that incoming gas line ball valve is
“open”. Verify that inlet pressure reading
is within acceptable limits.
Ignitor gap is incorrect.
Verify gap of igniter to right side of pilot
hood. The gap should be approximately
.095 in. (2.41 mm) to .135 in. (3.43 mm).
Module is not grounded.
Verify module is securely grounded to
metal chassis of appliance.
Module voltage output/Valve/Pilot
solenoid ohms readings.
Verify battery voltage is at least 2.7 volts.
Replace batteries if voltage is below 2.7.
Pilot lights but continues 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 shorted or loose connection in flame
sensing rod.
Verify all connections to wiring
diagram in manual. Verify connections
underneath pilot assembly are tight.
Verify connections are not grounding
out to metal chassis, pilot burner, pilot
enclosure or screen if present, or any
other metal object.
Poor flame rectification or contaminated
flame sensing rod.
With fixed glass assembly in place,
verify that flame is engulfing flame
sensing rod on left side of pilot hood.
Flame sensing rod should glow shortly
after ignition. Verify correct pilot orifice is
installed and gas inlet is set to pressure
specifications.
Module is not grounded.
Verify module is securely grounded to
metal chassis of appliance. Verify that
wire harness is firmly connected to the
module.
Damaged pilot assembly or contaminated
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. Clean flame sensing rod with
emery cloth to remove any contaminants
that may have accumulated on flame
sensing rod. Verify continuity with a
multimeter with ohms set at lowest
range. Replace pilot if any damage is
detected.
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.
