BGD36CFG TROUBLE SHOOTING GUIDE

BEFORE ATTEMPTING TO TROUBLESHOOT, PURGE YOUR UNIT AND INITIALLY LIGHT THE PILOT AND THE MAIN BURNER WITH THE GLASS DOOR REMOVED.

	SYMPTOM	PROBLEM		TEST SOLUTION
	Pilot will not light.	-	Wiring	Verify the "S" wire for the sensor and the "I" wire for the ignitor are connected
				to the correct terminals (not reverse) on the module and pilot assembly.
Makes noise with no		- Loose connection		Verify no loose connections, electrical shorts in the wiring or ground out to
spark at pilot burner				any metal object.
		- Module		Turn the ON/OFF switch to the "OFF" position. Remove the igniter wire "I"
				from the module. Place the ON/OFF switch to the "ON" position. Hold a
				grounded wire about 3/16" away from the "I" terminal on the module. If no
				spark the "I" terminal module must be replaced. If there is a spark the "I"
				terminal is fi ne. Inspect pilot assembly for a shorted wire or cracked insulator
				around the electrode.
		- Igniter Spark gap is		- spark gap of the ignitor to the pilot should be .17" tor 1/8"
		incorrect
	Pilot will not light.	-	Transformer	Verify the transformer is installed and plugged into the module. Check volt-
				age 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 3.2 and 2.8 volts A.C.
Makes no noise with no
		-	A shorted or loose	Remove and reinstall the wiring harness that plugs into the module. Remove
spark at pilot burner		Connection		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 value and pilot assemblies are properly grounded to the metal
				chassis of the fi replace or log set.
		- Faulty module		Turn the ON/OFF switch to the "OFF" position. Remove the igniter wire "I"
				from the module. Place the ON/OFF switch to the "ON" position. Hold a
				grounded wire about 3/16" away from the "I" terminal on the module. If no
				spark the "I" terminal module must be replaced. If there is a spark the "I"
				terminal is fi ne. Inspect pilot assembly for a shorted wire or cracked insulator
				around the electrode.
	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.
		- Module is not grounded		Verify the value and pilot assemblies are properly grounded to the metal
				chassis of the fi replace or log set.
		- Out of propane gas.		- fi ll the tank.

	and pilot lights, but		connection in sensor rod	also verify these connections are not grounding out to any metal.

				too high of an inlet pressure can cause the pilot fl ame to lift.) The sensor rod
				may need cleaning.
		- Poor grounding between		Verify that the wire harness is fi rmly connected to module

		- Damaged pilot or dirty		Clean sensor rod with an emery cloth to remove any contamination that may
				have accumulated on the sensor rod. Verify continuity with multimeter with

sensor rod ohms set at the lowest range.
