SYMPTOM
PROBLEM
TEST SOLUTION
Pilot will not light.
Makes noise with
no spark at pilot
burner.
Wiring.
-
Verify the wire for the sensor and the wire for the
ignitor are connected to the correct terminals (not
reversed) on the module.
NOTE:
Sensor has 3/16”
connection and ignitor has 1/8” connection.
Loose connection.
-
Verify no loose connections, electrical shorts in the
wiring or ground out to any metal object.
Module.
-
Turn the ON/OFF switch to the “OFF” position.
Remove the igniter wire from the module. Place
the ON/OFF switch to the “ON” position. Hold a
grounded wire about 3/16” away from the ignitor
(spark) terminal on the module. If no spark the
ignitor terminal module must be replaced. If there
is a spark the ignitor terminal is fi ne. Inspect pilot
assembly for a shorted wire or cracked insulator
around the electrode.
Igniter Spark gap is
incorrect.
-
Spark gap of the ignitor to the pilot should be 1/8”.
Transformer.
-
Verify the transformer is installed and plugged into
the module. Check voltage of the transformer under
load at the spade connections on the module with
the ON/OFF switch in the “ON” position. Acceptable
readings of a good transformer are between 6.2 and
7.0 volts A.C.
Battery backup (if power
is off)
-
Check batteries.
A shorted or loose
Connection.
-
Remove and reinstall the wiring harness that plugs
into the module. Remove and verify continuity of
each wire in wiring harness.
Improper switch wiring.
-
Troubleshoot the system with the simplest ON/OFF
switch.
Module is not grounded.
-
Verify the valve and pilot assemblies are properly
grounded to the metal chassis of the appliance or log set.
Pilot sparks but
will not light.
Gas supply.
-
Verify that the incoming gas line ball valve is
“Open”. Verify that the inlet pressure reading is
within acceptable limits, inlet pressures must not
exceed 14” W.C.
Out of propane gas.
-
Fill the tank.
