GE JVM 1650 Microwave Night Light does not work

My GE JVM 1650 Microwave countertop light does not dim when I press the button for the night setting. The display says night. I can hear a relay pick but the brightness of the lights is the same brightness for both normal and night settings. DOes any body have a wiring diagram. I suspect it was miss wired.

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.

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

If your relay is bad and you want to replace it yourself, it is part # 3501-001050 and you can find helpful exploded view diagrams of your microwave and order that part here.

Be sure to also do any needed circuit board repair with 30AWG wire to prevent it from doing worse damage if another bulb shorts.

Ge spacemaker microwave jvm/1650


Mmmm it's so easy,
First disconect the power, take the cover off, moslitly there would be 5 screws and two tab's on the top.
inside on the right hand side the magnetron it's a sylver box measuring about 4 in x 4 in x 5 in. It will have a plasic cover moslitly that would have to be remove first then on the magnetron there is 4 crews and one connector.
It should fall downard after.
If you have a power supply after the secondary , that may also be your problem.

Regards
