I'm hopeful to get some pointers on how to fix this issue.

About a week ago, my wife mentioned that the oven lights wouldn't turn off when she was done cooking, but that after the oven had cooled down, she was able to turn them off. A day or so later, same problem, but this time the lights would not turn off after cooling down. I turned off the main power to the oven at the breaker and left it off for a couple hours. When I turned the power back on, the lights remained off.

Yesterday, the problem returned. Tried power cycling it again, but now the lights remain on.

I have tried opening the door and manually depressing the door switch with no effect. I have removed the door switch and tested for continuity, and it tests fine.

When I touch the keypad to turn off the oven light, it makes a beep, but there is no 'click' from the relay. I suspect that the relay board needs replacing, but is there any way for me to test it first? Is there anything else that I should check?

Thanks,

Mike

Hi Mike,

Yes, its got to be that oven light relay if the door switch is fine.:)

To test it use a multimeter to ohm test it, unplug the range first before you do that. Continuity means its stuck ON, no Continuity means its OFF.

Looks like that oven light relay is labeled RY1 on the relay board.

Here's the relay board for your model: EBR60938302 Pcb Assembly,sub

Since your in Canada(Ships to Canada) here it is:
EBR60938302 Sub power control board assembly
