SOURCE: microwave no heat

The "HUMM" indicates a breakdown in the High Voltage Side. The loud "POP" was the breakdown. You have only four Components in the High Voltage side.

1. High Voltage Transformer. You can eliminate this as the problem. Why? If it was the problem it would have blown the line fuse, and would have given off a burned transformer smell.
2. High Voltage Diode. Usually will Burn or Pop when shorted, but will then OPEN the Circuit and there is no "HUMM".
3. High Voltage Capacitor.This is the Silver Can with the two terminals on top. It can SHORT internaly between the plates (the two terminals) and give the "HUMM".
4. Magnetron. This is my number one suspect. A SHORTED Magnetron.

SOURCE: Owners manual for Kenmore Elite Microwave Model 66462

A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########

You can just enter your full model number at the Sears parts site.

On the resulting page, look to the right for the blue "View manuals" button. Click there.

d:%5cele%5crepair%5cmicrowave%5ckenmore_sears%5cview_manuals_button.jpgd:%5cele%5crepair%5cmicrowave%5ckenmore_sears%5cview_manuals_button.jpgd:%5cele%5crepair%5cmicrowave%5ckenmore_sears%5cview_manuals_button.jpgcaab351.jpg

That Sears-related site has many free manuals. While the manuals they list there are all free, they will ask you to register.

Many times, the owner's manual will have the installation instructions inside.

If yours is not listed there for free, you would have to order it through the
Sears parts site.

SOURCE: Kenmore over range microwave oven / no power at all

Unfortunately, there is a good chance that when the bulb shorted out, it damaged the control board. The only way to know for sure is to do some electrical testing with a volt/ohm meter and the wiring diagram located within the appliance. The relays for the fan and the lights are part of the board. The power should always be disconnected when these bulbs are replaced or the board will be damaged. We would have an appliance repair person take a look to see what the deal is with the microwave.

SOURCE: kenmore microwave model number 401.80084700 Displaying -SE-/-5E-

-SE- error means you have a shorted membrane keypad.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and of course one should never leave a microwave unattended while cooking.

There are three ways you can get it fixed:

DE34-00178X SWITCH MEMBRANE $20.30
ref#53 membrane keypad
take yours off as in the video at our site, peel the old keypad off as in this handy guide with pictures , clean the surface, stick on the new keypad
order by part number here
(We can do this job for you for a total of $70.25, but as you can see, the other two options are more practical and economical)

DE94-01647A ASY CONTROL PANEL $39.01
ref#66 control panel frame with keypad
take yours off as in the video at our site, disconnect the keypad strip as shown here, move your circuit board to the new frame, reinstall
order by part number here

DE94-01648A ASY CONTROL, BOX $58.12
ref#59 complete control panel assembly with frame, keypad and circuit board
take yours off as in the video at our site, then install the new one
order by part number here

If these parts are not in stock, they should be available in about a week or so.

Yesterday, I went to use the microwave and as I pushed start, I heard a loud pop and saw sparks behind the vent cover. The microwave light and turn table work fine, but it does not heat. Is it repairable?


sounds like your magnetron went out . check how old it is, sometimes the manufacture gives a 5-10 yr warrenty on part if no warranty on unit then it may not be worth fixing depending on how much u spent on it. part roughly 89.99-139.99 labor 85-165.00 depending on who u use and were u live. hope this helps . thanx..

Light no longer works


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 or so.

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.

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.

The lights can can be inoperable or stuck on or no bright, too. Sometimes this will similarly affect the exhaust fan operation or inside light, too.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

Will not heat


The loud pop was almost certainly the high voltage diode going bad. To find parts, I suggest you call the number on your owner's manual or check with the store where you bought it. Sunbeam may not make this part available, so be prepared. Maybe they have authorized servicers in your area. Ask them about that. Good luck.
