Troubleshooting Procedures

!WARNING

To avoid risk of electrical shock, personal injury or death; disconnect power and gas to oven before servicing, unless testing requires power and/or gas.

Problem	Possible Cause
	Failed ignitor
	Gas pressure too high
No gas flows to burner.
Ignitor glows red.
	Failed gas valve
	Loose wire connection or broken wire
	Ignitor positioned too far from burner
	Dirt or grease in orifice or burner
	Insufficient gas pressure
Gas flows to bake/broil
burner, but burner does not
light.	Power outage

Power outage ..............................................

Broil burner shuts off shortly after the start of self-clean operation. Bake and broil

functions operate normally.

Control Error ................................................

No power to fan motor.................................

Fan motor does not operate.

Failed fan motor or winding/frozen shaft .....

Correction

•Check ignitor current draw, 3.2 – 3.6 Amps. Replace ignitor, if it fails test.

•Check for correct gas pressure. Natural gas pressure should be 4" WCP and LP gas pressure should be 10" WCP.

•Check gas valve for continuity.

•Verify all connections are clean and tight, replace broken wire.

•Reposition ignitor closer to bake/broil burner.

•Clean orifice or burner.

•Check for correct gas pressure. Natural gas pressure should be 5" WCP and LP gas pressure should be 10" WCP.

•Verify power is present at unit. Verify that the circuit breaker is not tripped.

•Replace household fuse, but do not fuse capacity.

•Verify power is present at unit. Verify that the circuit breaker is not tripped.

•Replace household fuse, but do not fuse capacity.

•See “Control Systems Troubleshooting.”

•Check for 120 VAC supplied at fan motor. If no voltage is present, check for broken or loose wiring between fan motor and relay board. If voltage is present at fan motor, go to the next step.

•Check motor winding for continuity. Check for a frozen motor shaft. Check for broken wiring between motor and neutral terminal block.
