Kenmore Elite Ultra Heatwave Microwave - Model 665 63799305

Over the oven.
Manufactured date is August 2007. After cooking at 100 power for about 20 minutes, popping sound starts 5 minutes after cooking done and dish is removed. Popping sound lasts for about 10 minutes. If door is opened during the 10 minutes, the sound will stop; however the sound resumes when the door is closed. The exhaust fan comes on automatically.

This oven replaces an old microwave that exhausted to the outside.

SOURCE: microwave runs constantly

If it's less than a year old, it's under warranty and you should call the nearest Sears store for free repairs. Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked 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)

SOURCE: Kenmore Microwave turned off, not back on

Both of you have suffered at least a failed fuse and these are nearly always inside the housing.
Sometimes the fuse (which are calibrated pieces of special wire) will fail from metal fatigue but it can also mean that either the heavy current, high voltage rectifier that produces the magnetron voltage or the magnetron itself has failed.
Some units have separate fuses for the control and display electronics and another, very high current (~30 Amp)  fuse for the magnetron circuit.
Do not attempt to open the unit unless it is, and has been, unplugged for an hour or more.
Gaining access is generally not difficult and either the back panel or top can be removed with a half-dozen screws. The fuses may not always look the same but the most common is a ceramic case with metal ends and it might be pushed into a simple fixture that snaps over the metal ends.
If you do not own a simple digital multimeter, I recommend buying one. They are available from various sources; electronics and auto parts stores will have them for under $20 US or if in the US, check your local directory for Harbor Freight outlets. I have bought several for $3.00 there and scattered them around vehicles and the normal junk drawer in the kitchen. Even the simplest of these will have several basic ranges and the resistance range is the one used for checking that fuse.       Remove the fuse from its clips and measure it between the metal caps on the low range (often 200 Ohms). If the display does not change, the fuse is blown; if it shows something in tenths or at least below 10 Ohms, it's OK.  
If you care to delve further into your microwave at all instead of replacing it (they have gotten almost too cheap to repair), comment back here again and I will try to guide you further.

Sounds like a bearing is tightening up when it get heated up with use. Then after a cool down period it works normally until using it heats it up again. Eric

Kenmore elite microwave 721.80833 stops cooking intermittently


Check the door switches if one is bad it may think the door is being opened and stop the unit from running. If it is from a bad connection it will get worse as it gets hotter while running.

I have a Kenmore Elite Ultra Heatwave Technology microwave which started smelling "electrical" and it just quit. The lights still work and the panel still works, but it does nothing when you hit...


This almost always means the magnetron tube, which supplies the microwaves, has failed. The smell comes from parts inside the tube that overheat and burn out. Once the tube goes, everything else appears to work but there's no heating without the microwaves.

The tube can be replaced, but the repair should be done by a professional. Microwave ovens are very hazardous to work on, and if the repairs aren't done properly then microwave leakage can be a concern. The tube generally costs around $50 to $75, and I have no clue what labor is going for these days. If you want to keep this oven, let a service technician give you an estimate for the repair. Then you can compare the repair cost against that of a replacement oven. For countertop models, it's usually cheaper to buy a new oven, but for an over-the-range model the repair might be worthwhile. The ovens are more expensive, and yours might be a custom installation.
