When i use my kenmore model 970-86193-001 it will work for maybe 10 minutes and then will not heat any more,take out of hole in wall and leave all night and next day will work.

The child lock may be on.

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 you still need, help, I'd check the owner's manual.

If for some reason you don't have yours, you should be able to get it from the Sears parts site.

Just enter your model number there.

Hi,

I would suspect that when the microwave oven was on the table the vent or air openings were restricted by the table. Without free flowing air the control and other components could build up heat. It is doubtful that you built up enough heat to damage anything as this unit has more than one over temperature safety devices built into it.

That being said, the excess heat could weaken something internally especially on the control that would cause it to fail sooner than later in life.

My advice would be to leave it unplugged until it is mounted back on the wall per the instructions and use it then as normal. If it fails in the next year or so replace it at that time.

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.

Sadly Kenmore only offers parts for 10 years. The truth is a new microwave for 50 dollars will be much more energy efficient than your 21 yr. old model

"d" may mean demo mode. The first thing to try is a "hard reset". Unplug it from the power outlet for 10 minutes, plug it back in, set the clock, then try again.

First of all, is the hole a factory one that you never noticed before? If so, leave it alone. I know that microwaves generate a lot interior heat and it needs to escape someway. Secondly, if it is not a factory made vent hole and you can't be sure if it caused from a lot of use, and if the oven still works fine, I would not worry about it if it were me.

F3H is a humidity sensor error.

If it still fails, you have a bad sensor.

You can usually find exploded views and order parts by entering your model number at the Sears parts site.

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, and locating components.

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)
