Kenmore microwave model 721 loose door

When I pull the handle to open the door the bottom comes apart a little. It doesn't come all the way off...yet so trying to fix it before it gets worse. Any suggestions?

Loose bottom hinge - slide the microwave to the edge of the counter, and look at the bottom hinge - you may have to remove something to see clearly. Its likely you are missing a screw or the screws have worked themselves loose.

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: KENMORE MICROWAVE (HOUSEHOLD) LOCKED

It sounds like you press STOP two or three times to lock it. Maybe that (or another key) will unlock it.

The lock / unlock procedure will be covered in your owner's manual.

Or you can try a hard reset - unplug it from the wall for one minute, then plug it back in and try again.

If you don't have your manual, you can get one here. (Enter your model number without any spaces)

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.

Kenmore 721 microwave fan turns on by itself

I have the exact same problem with my Kenmore Microwave model 721 that we bought in October of 2005. The Fan will just randomly turn itself on even when we are not cooking. It has been doing this for the last few months and is starting to become more frequent. There is no way to turn it off except to unplug it for several hours.
Was there a recall for this defect ?

Sear's microwave falling apart

If this is and Over the Range micro, the exhaust fan needs to run ANYTIME the cooktop is on. They make things for quantity and not quality, so the plastic has little tolerance for heat. Running the fan, diminishes heat off the front of the unit. Also, the micro MUST be at leat 24" off the cooktop.

Your model number prefix of 721 means it's made by LG / Goldstar.

F9 code on an LG means either a bad door switch or a loose door switch mount.

Even though a door switch clicks, it may still be bad inside.

This can be caused by slamming the door or by habitually opening the door while it's cooking without hitting the Stop pad first.

If you or a friend decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can find helpful exploded view diagrams and order parts by entering your full model number here: http://www3.sears.com (the 3 is correct)

Replace handle on microwave oven

The part number for a new handle is 820941 and costs approx. $19. If you already have the part and are wanting to install it follow these steps:

You can either do this with the door in place, or remove it. To remove it, you open the door all the way and push up at the hinges. The door should lift off the hinge pins.

1. On the back side of the door (the side that faces the interior of the oven) is a plastic facing around the perimeter of the glass.

2. There should be a series of slots or grooves around the facing that you can place a small screwdriver in.

3. Carefully (I cannot emphasize this enough) lift around the facing until it comes loose. You may not have to remove it all the way around the door. Sometimes you can gain enough access by lifting on the side where the door handle it mounted.

4. Under the door facing are the mounting bolts (or screws). Remove broken handle and install new handle.

5. Reinstall components in the reverse order as stated before.

If you are waiting to order the part for your oven, you can get it at repairclinic.com. The part will be shipped directly do you for a nominal shipping fee.

This should be a fairly simple repair that only takes about 10-15 minutes.

Again, be careful with the door. If you break it, a replacement door costs over $200! Good luck and let me know if I can help further.

Bottom screw on handle loose

All my micros had the screw go through the handle into the micro...no need to take door apart, just screw it back in. Why would you need to take the door apart?
