Convection Fan Troubleshooting

Convection Fan Troubleshooting

Problem	Possible Causes	What To Do
Fan motor buzzes	Open capacitor	Harness, terminals, or bad capacitor.

	Open winding as
	indicated by ohm
	check red to black and	Replace motor.
	blue to black (approx.
	60 ohms each)
	Check voltage CCW
	to N when fan is CCW
No fan operation	- should read 120VAC	• If no voltages, replace ERC.
No fan operation	in Convection Bake.
	in Convection Bake.	• If voltages OK, check harness or winding resistance.
	Also, CW to N when CW	• If voltages OK, check harness or winding resistance.
	as indicated by ERC
	display
	Shaft or blade rubbing	Loosen screws/re-adjust position/tighten.
	on oven liner	Loosen screws/re-adjust position/tighten.
	on oven liner
	Jamb switch NC to C is	Replace jamb switch or check harness.
	open	Replace jamb switch or check harness.
	open
	Loose shaft nut	Tighten shaft nut. Do not bend blade.
Fan loud	Loose convect cover	Tighten screws. Use larger screw if stripped.
	screws or cavity screws	Tighten screws. Use larger screw if stripped.

Oven Sensor Ohmmeter Test

Remove ribbon cable from the upper oven door. Make resistance measurements of the sensors with the exposed terminals of the ribbon cable.

	Upper Oven	Pin 13 to pin 14
	Sensor	Pin 13 to pin 14
	Sensor
	Lower Oven	Pin 11 to pin 12
	Sensor	Pin 11 to pin 12
	Sensor
