Re: kenmore elite microwave oven

A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the
thermostat to open.

When it cools, it closes the circuit and allows power through again.

If it's random, it may be a bad connection, usually on the control board or fuse holder.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

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

My Kenmore elite microwave model 401.88523011 has lost power. The electrical outlet still has power to it. Is there an internal fuse or circuit breaker that may be causing the power outage?

Your microwave has an internal fuse. Usually 10 to 20 amp. You can pick some up at home depot or radio shack. Make sure you get the same amps and volts as the original fuse. Will be printed on your microwave some where usually. And if its one that is part of a double oven deal make sure that you check you're circuit breakers for the kitchen. Good luck.

The display screen on my Kenmore Elite Microwave model #721.80802400 has frozen on 13 seconds! does not respond to turning or pushing dial. Only works by pushing manual. No idea about cook times. Is this...

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

If it still doesn't work, it may be a controller issue which can be repaired.

Kenmore elite microwave oven displays "Locked" and will not respond

My Kenmore Elite microwave (don't have the model number in front of me) also mysteriously locked its own keypad (we were sitting in an adjacent room, heard a strange beep, and got up to find the LED reading "Locked."). I pressed and held down the Stop/Clear button for ~10 seconds and it returned to normal.
