The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.

The repair service saves you a lot over the cost of a new control unit and comes with a full year's guarantee.

At our site, we now have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Feel free to contact me directly for more information & help.

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

Bare ile bo100 microwave won't go keypads seem to be ceased lights ok on display pls help


You can try unplugging the oven for at least 15 minutes to see if the control panel will reset on its own.

If that doesn't fix it, you might have a bad control panel, or oven may not be properly grounded.

How do I fix the key pad of a Kenmore microwave model 401.80084700?


I don't know of anyway to repair the keypad. Usually replacement (of the keypad/control console) is the only option. But you might want to remove the ribbon cable that connects the keypad to the control board behind it, clean it with a degreaser (like Fantastic or 409), dry it, and re-insert it, and then try again. (Remember to unplug the microwave oven first before you try that!)

Microwave turns on but keypad doesn't respond.


If it's brand new it should easily be returned to the manufacturer (Or retail outlet) So dont worry, Just take it back tell them your problem,. They'll probably be happy to help, This is a situation where you can do little if anything and are probably facing a defective product

Buttons on microwave


testing every step and fix it. God bless you see the diagram attached

Microwave Buttons Don't Work
Touchpad and Control Panel


If the microwave buttons don't work the touchpad and control panel assembly are probably defective.
Touchpad


If the microwave buttons don't work the touchpad might be at fault. Generally speaking, if the dishwasher display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.
User Control and Display Board


If the microwave buttons don't work the user control and display board are most likely defective and will need to be replaced. If some of the buttons work and some don't, it is more likely a touch pad problem and the touch pad will need to be replaced.
Main Control Board


If the microwave buttons don't work the main control board is most likely defective and will need to be replaced. If some of the buttons work the touch pad is likely the problem. If none of the buttons work the problem may be in the main control board.1_24_2013_5_23_47_pm.gif1_24_2013_5_24_54_pm.jpg

My microwave doesn't work, but display works


I would strongly consider replacing the microwave oven, prices have dropped considerably. The problem you are describing is in the keypad controller board.

The microwave doesn't work at all. no display, light, anything


Plug a lamp in the wall receptical in place of the microwave oven, if okay! it means the main fuse in the oven has blown. There are a number of reasons why this happens, a bad fuse, door switch that has malfunctioned, "common" cracked high voltage diode, shorted capacitor, and an open magnetron. I suggest a professional.

I have owned a AMC5101AAW for about three and a half years. It has been a good microwave,perfect for my needs. The display went black and the buttons didn't work right after I boiled a cup of water for...


It sounds like it could be just a bad crimp connector supplying power to the whole system, which would have to be the fuse holder on the mains input panel.
Worth a look!

No display on LCD panel on my whirlpool microwave


I do not know what procedure you used to replace the door, but if the buttons and display were working fine before you replaced the door then it seems that there is a plug not plugged into the control display panel. Other than that the low voltage power supply may not be providing the needed voltage for the display and only for the logic circuits which are a different voltage. With the microwave unplugged, take the cover off and look at all the connectors and make sure that they are plugged into something and none that are not plugged in. They should all go somewhere. To answer your original question, there is only one main fuse to the microwave. The circuitry in the control panel operates on low voltages +/- 5 volts or +/-12v so that part is not fused. What I recommend also is to go back mentally through the procedure you used to replace the door and that may give you a clue as to what you unplugged, although you should not have to unplug anything.
