The owner's manual (here) does not mention that as a feature, so I would assume the oven has a defect and would need to be returned to your dealer to be exchanged under warranty.

SOURCE: After changing a blown oven light, the clock works but nothing else turns on, including the fan, light, microwave

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.

SOURCE: When new microwave is turned on, the lights in the kitchen dim.

Sounds like your microwave's outlet is on the same circuit with the lights.

High-current devices like microwave ovens should be on their own breaker if possible.

If the dimming is very slight, it may be okay.

If it's considerable, it may be a good idea to run a separate line to the microwave's outlet - especially if it starts blowing your breaker!

SOURCE: GE JVM 1650 Microwave Night Light does not work

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.

Frigidaire Mod: FGMV174KFB Door won't latch


Good Morning Friend,

I understand the door will not latch on your Frigidaire microwave, model# FGMV174KFB. Typically, this would not be a do it yourself repair, as you are working with your microwave, and there are no step by step repair instructions. I suggest contacting your local authorized technician for further assistance. They have been trained on your appliance and should be able to fix the latch on your door with ease. Hope this is helpful.

-Best Regards-

My microwave wont heat up but runs normal


The make & model number would be helpful. There are alot of veriables that might cause this to occur. How long was the MW in use (the unit might have been to hot and the safety engaged) keeping the fan on to cool it down. There could be an issue with with one of the door interlock switches. Depending on the engineering, the control board could have had a hickup via a over current & shut down to protect itself. During the cut out was the cavity light on when the door was open. was the display blank. If you unplugged the unit waited a minute & then plugged it back in, did it operate again. It is not a good idea to open the control panel up, if your do not understand how to do basic electrical troubleshooting.

Dim control panel unable to read


Removed the amber glass which obscures the display enough to remove the wiring from view. This also allows you to see the characters much more clearly. You now can see the inidvidual light elements.
It's not too bad, people don't even notice, but they do notice you can now tell the time and see what the oven is doing.
