Question about Microwave Ovens

Kenmore microwave Model #"721 8924681" "L" in lower corner

For some reason an "L" appears in the lower left corner of the LCD and the oven will not heat. If you unplug it for a short time then plug it back in it works fine but before long the "L" appears again.

That sounds like a code for "lock". It may be a failing keypad.

Your model number is not showing up. Is that correct, or is it a non-US model?

I have a Kenmore Microwave 405.72123310. The microwave turns on and the turntable turns, but it does not heat. Is there a fuse I can check for this?

You really don't want to take them apart do to radiation. Take the screws out in back plate. Carefully and remove and look in to see if you see black burnt spots. If you see any then chances are the main board shorted out on microwave.DO NOT STICK ANY TOOL IN MICROWAVE IN BACK. Some do have a round fuse in back.If your does take it out with some heavy plastic. Make sure before you take back off unplug from wall and the push start 3 times with 5 second apart. This will allow all electric in the power reducer to discharge. then you can work on it. On sides of use it will tell you what amps it is. Good Luck

My microwave has a new icon in top left corner and no buttons will work now. Time still displayed but nothing works. I try pushing any button but nothing. What's going on?

I know this sounds basic but have you tried to unplug it and plug it back in...?maybe also look for a reset button somewhere in the back ?

A small blinking light on the left upper corner of panel after a power outage and I can't do any command. The interior lights don't even come on when opening door. I already reset the breaker

Unplug the microwave oven for 10 minutes in a attempt to reset the microprocessor ic, press and hold the start button for the same time and release. Now plug everything back in hopes it will restart, if no change! the keypad control board will need to be replaced along with other unknown parts, due to the nature of damage far cheaper to replace.

Oven won't shut off

One of the door switches is defective, caused by a build up of food particles or normal ware, to correct this a professional will need to identify the problem and replace it.

Hey, my microwave turns on, allows me to set the time, but when i click the fan or heat it shuts off, and doesn't come back on; after a while if i unplug and plug it back in it starts working until i try...

Sounds like a faulty connection or short to me , you could also look out for a dry solder or burn out on the circuit board. Needless to say if you arent sure what your doing or looking for when I describe a dry solder it's a solder thats cracked & shorts out when your appliance heats up. But from what you say it sounds like the circuit board or a lose connection to me , unplug it leave it for a while before you try having a look if you descide your going to & make sure that you replace everything back as it was after all you don't want to cook the people on the outside just the food on the inside.

Limited heat power

It sounds like the transformer is shorting out on you but is not completely shorted.It will be shorting out on the output side of the transformer.this will give you a lower output level,and will cause the microwaves to be weaker.(less turns of wire in the secondary of the transformer).The short will probably get worse.Simply replacing the transformer should cure the microwave.

My Microwave is displaying F6 and running when plugged in.

I found a sheet that says to check wiring to main or microwave relay for shorts. If no shorts found, replace control board.
