Kenmore microwave won't heat

My daughter thought she set the timer, but instead the microwave ran for 10 mins. with nothing in it. Now it won't heat. Can it be repaired? Is it worth repairing or should I just replace it?

SOURCE: microwave won't come on

I am a recently retired appliance engineer of 20 years, i am reluctant to help with microwaves because of the dangers, the store electric even when unplugged, but it sound just like an internal fuse, these are special quick blow types, can be bought from most electronic high store shops, and replacements must be exact match, if a replacement blows there is another fault and don't recommend self repair work with safety and remove the plug first etc oh the fuse is just inside following the mains wire in, and normally on a small circuit board if i have helped please rate me

SOURCE: Sharp mdl R-1870 convection microwave runs for 1 min

This is a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.

The damper is a door inside that opens or closes depending on cooking mode. If the controller senses that the door is not in the right position, it will shut down the cook cycle.

Sharp models stop after 59 seconds.

See the attached sample photo.

We have the service manual and have uploaded it to our site:

SOURCE: overheated microwave

Hopefully the magnetron thermal cutout or thermostat protected the magnetron from destruction!

It may be the fuse, which is usually located behind the grille or on the floor of the oven behind the control panel or between the door switches.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

Kenmore 62463 / 721.62463201 Stainless Steel 1200 Watts Microwave. My daughter used it as a timer for reading and set it to cook for 30 minutes with nothing in it. It turns on but is loud and no longer...


You probably fried the magnetron(it actually makes the microwaves that do the cooking). I bet you will find the magnet is broken(from excessive heat). There should be a diagnostic guide sheet somewhere inside the housing(due to running production changes,this is a guide for the pros to test the power supply,magnetron,etc with an ohmmeter to determine which is defective.

Hi,

Without food for the microwaves to be absorbed by, the magnetron (heating device) would have most likely overheated. There is a thermal overload switch (safety device) that acts like a fuse and turns everything off if overheating occurs like that. You would need someone that could take the microwave down, disassemble and check to see if the 'fuse' is bad or the magnetron is bad, they can both be checked with an ohmmeter. If you need to hire someone to do this, it may cost you more than the cost of a new unit if the magnetron is the item that has failed.

It could be the fuse. You will also need to check the condition and alignment of the door switches.
