You put a mounting plate on the wall behind where the unit will be mounted. Then the microwave hooks onto the bottom of the mounting plate and you swing it up to the cabinet above it. Then you must screw 2 mounting screws through the floor of the cabinet above into the bracket on top of the microwave.

SOURCE: F7 Error code on Kenmore

On the tech insert found in a cavity under the cover of my Kenmore MHC, the F7 code means the inverter board ($90 - $130 street price Fall 2008) is bad and needs replacement. I am having this problem, and verified that the magnetron was not shorted to ground with an ohm meter. I verified with a volt meter that the magnetron was not getting any voltage applied across the cathode from the inverter board when the microwave is running ("WARNING"- don't do this test with the magnetron connected.) I have an inverter board on order.

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!)

Why is my microwave model 60609 making extremely loud noise and not heat?


Usually that is a sign that your magnetron tube has gone bad (shorted out).

With the full model number, chances are we could have helped you more.
If the cooktop lights recently failed, it may need circuit board repair.

Or it may be a failed hood TCO.

Kenmore Microwave Hood Combination 721.80019 does not heat. I follow all the troubleshooting procedures. Nothing solved the problem. Help!


My kenmore microwave will not work. The light stays on inside, buttons will push, but the start button does nothing. I've tried everything. The last thing I did was express defrost which was fine. Could it be something really simple? I hope so.

Kenmore Microwave Hood Combination: over the stove Model #721.80602500


Disclaimer: I'm a DIYer, not a technician.

Our GE over-the-range microwave stopped producing heat yesterday while warming part of the T-giving feast. Everything else (fan, control panel, light) works fine.

After disassembly and testing last night, I discovered a defective "secondary door switch." Your Kenmore uses a similar switch (~$19 on-line), and that might be the problem. But it also could be other things, such as a bad thermal cut-out.

If you know anyone who's handy with a multimeter, most of the basic diagnostics seem to be pretty straightforward.
