That's common - it's a problem on your control panel. We regularly repair these control panels for only $32.50 nationwide. For critical safety info & detailed disassembly info, see our link in our FixYa listing here: http://tinyurl.com/yzjozk Let me know if you need further help. I appreciate your kind rating!

The problem is almost certainly on the control panel, which we repair nationwide for $39.95 postpaid.

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.

This often can affect the exhaust fan operation, too. The lights and fan can be inopoerable or stuck on.

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and

disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.

At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

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.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

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

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.

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.

Sometimes this will also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

In your case, it may just be a shorted dimming diode, a black diode usually located between the light relay and the connector.

(Not to be mistaken for the tinier red-bodied diode on the other side of the relay that protects the relay coil).

If it is shorted, you will have bright lights in both the bright and dim settings.

In case you or someone you know has the tools and experience to desolder and solder small components, the replacement rectifier diode is not critical and can be any of these:

1N4001, 1N4002, 1N4003, 1N4004, 1N4005, 1N4006, 1N4007, NTE116, or NTE125 some of which are available form Radio Shack.

At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

SOURCE: GE Microwave oven vent fan not working

You are correct the fan motor is either stuck or needs replaced.

There is no way to do this without removing the entire microwave. In case your not familiar with how microwaves work, there is a capacitor that is very large inside and can hold a charge even after it is unplugged for up to 24 hours, please take action to prevent getting shocked.
