Product is GE Microwave (Spacesaver-type) JNM1731DM1BB. New surface light bulbs installed. Unable to turn them off or change from bright to dim

Bottom lights are controlled through relays on the main control board which is mounted on the back of the touch pads (control panel).You can check and see if wires are touching each other on the board but my guess is the board is defective and needs replaced.

Fgmv174kfb dim display

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.

LED readout is getting very dim. I reset the computer but it's still dim, and only about half the numbers are visable.

The issue is with the display panel that is bad or the connection to the control is loose. TO check what is causing this issue you will have to take it apart and check the board, if bad then it should be replaced. Hope this helps...

Surface lights are not turning off and stay on Bright. Any thoughts on how to fix this?

Unfortunately they are controlled by the circuit board and it is not repairable. The board will have to be replaced.Depending on age of unit you should call manufacturer and see what they say < might repair free>

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.

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!
