Need step-by-step instructions on changing the night light or work light

I repair these on a regular basis. See http://www.microwavecontrol.com

There is a possibility that the light relay is stuck on. Sometimes a sharp tap on the relay will fix it. If not the control board will need replacing.

We see and repair this a lot. The problem is on the control board, which we regularly repair for $39.95 nationwide.


This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

The lights can can be inoperable or stuck on or stuck in "night light" mode. Sometimes this will similarly affect the fan operation or inside light, too.


We'd also recommend buying top-quality bulbs.


They can blow if subjected to vibration such as door slamming or a weak floor, or electrical fluctuation, especially if they are cheap bulbs or they are left on all night.


Instead of having the board repaired, you can order a new control circuit board / smart board if that's economical, and since your sockets are bad, they will need to be replaced, too.


You can find links to helpful exploded view diagrams and part ordering help here. I recommend that you bookmark that link to your

favorites.


There's a YouTube video available showing how to remove a typical over the range control panel assembly in under 5 minutes.


If you're changing the board yourself, you'll need to detach the keypad connector:



Some connectors will have a lock.


We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

I would check the door switches with a digital meter, set to ohms, disconnect one wire from switch and test for open and short by pressing door switch, if you hit one that tests the same when pressing and releasing, switch should be replaced.

If there are 2 bulbs try swapping them around. If the night light works then you just need a bulb. Take the bad one with you and match it up at a parts store. Some actually have a dimmer circuit programmed in the board and that will not be a easy fix. Do you hear a click when you try to activate the night mode? If you cannot find a bulb or do not want to replace or repair the unit just disclose the non working light. I was in real estate for a couple years and a burned out bulb will not be a deal breaker as long as they are told up front.

Q - While trying to change the light bulb on the oven, the bulb broke. When it did, it threw the circuit breaker and the whole oven went out. After resetting the breaker, everything on the oven works except there is no power to either light socket. Any ideas or suggestions on what to replace?
A - You tried to change the light bulbs with the power still on.....tsk tsk!!
Hate to say this....but probably blew out part of the circuit on the smart board ( the brains behind the key panel you touch ) when the short blew. The light relay on the smart board may have been damaged but 9 out of 10 times when I check them, the board itself is damaged.
check out this problem.
please do rate the solution.thank you for using fixya.keep updated.thanks,

This is a problem with the control panel assembly, which we repair nationwide for $39.95. This is most often caused by the filaments shorting when the bulb blows, or by not disconnecting the microwave from the power line when removing or installing a bulb.

The lights do get very hot, so they must be a sufficient distance from the lens. Was there an instruction sheet with the new lens? You may need to adjust the sockets upward. You might call a local GE-authorized servicer to see. Concerning the vent fan, this is a problem with the control panel assembly, which we repair nationwide for $39.95.

The problem lies in the circuit board / control panel. We regularly repair these control panel assemblies nationwide for 32.50.
