My built-in KitchenAid microwave/convection oven/oven fan comes on and goes off spontaneously. I have to turn it off at the breaker. Otherwisel, both micro/convection and the lower oven are functioning beautifully. Any ideas?
I'd say it's the internal cooling fan. The green "on" light is also illuminated when the fan comes on, but the interior light is off and the turntable does not turn during this "phantom" operation. The model# is KEMS376TBL3, serial# XA0202483. It went about 24 hours operating just fine, then spontaneously came on again this afternoon so I had to throw the breaker to turn it off. Any ideas?

Guess what, I think I have the same model oven and microwave.It's a #KEMS376. And we have been having this problem for many years now and haven't looked into getting this fixed.
We end up flipping the breaker switch on and off each time we want to use it or the "fan" will turn on mysteriously, it has gotten worse over the years where it would turn on almost immediately after each microwave use.
Any easy fix?

There are a couple of safety thermostats in the oven to shut down power if something overheats. One is on the magnetron tube (the microwave source), the other is on the cooking cavity. These sometimes go bad. There's also a power line fuse that may have failed, or become loose in its mounting clips. These can be tested with an ohmmeter; they should all measure very close to zero ohms if they're good.
Another possibility is that the control circuit board in the oven may have failed. I have worked on several Sharp ovens where the power transformer for the board has gone bad for no good reason. If the board goes bad the oven may appear to be dead as well.
Microwave servicing is best left to professionals. If you're thinking of keeping this one, take it to a service shop (or call for home service) and get an estimate. Then decide whether to repair or replace.
Hope this has helped a little. Thanks for using Fixya!
some of these unit detect heat from the stove while cooking.there are designed to turn the exhaust fan on until the temprature gets cooler to prevent any interior damage.
there also could be a problem with your microwave circuit board.
check with whirlpool and see if there is any recalled notices for you microwave
Please note that FixYa is not currently notifying us Experts when Clarification Requests are answered.
So please post a NEW question, and please
include your brand name and the full model number from the tag in or on
the unit, as well as the answers to these questions:
Which fan is it?
The internal cooling fan, which comes on automatically whenever the unit is microwaving?
Or the hood vent exhaust fan which you can turn on and off manually?
Or the convection fan, if it is a convection model?
When is it coming on?
Is it coming on whenever you cook on the stove top?
Q - The fan in my microwave oven is not running will this hurt my microwave? A - YES, the fan cools the magnetron and electronics, take the microwave in for service, most fans are not too expensive to replace. Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay.....
Yes this is a touchpad issue. As you have noted the crisp button is stuck and this is the cause of this. You can try removing the keypad and push up the pressed button. If its jammed then replacing it is the only way.
I'd say it's the internal cooling fan. The green "on" light is also illuminated when the fan comes on, but the interior light is off and the turntable does not turn during this "phantom" operation.

> The green "on" light is also illuminated when the fan comes on
This seems like a good clue, but which light? Where is it?
The manuals for your oven and for the microwave can be downloaded here if you don't have them.
Sorry for the back and forth, but I'm pretty sure I can figure this out for you with just a little more info.
Can you look at the manual and let me know which light that is and where it is, or upload a good digital photo?
Do you know which fan it is coming on by itself?
This should have three fans:
1. an internal cooling fan that comes on automatically when you microwave
2. A hood vent exhaust fan that you can turn on and off
3. the convection fan that is only used when cooking in convection mode
Also, please let us know your model model so we can help you best.
