Ihave a SAMSUNG over the range microwave that shuts off. It will run for 1-5 minutes then shuts off and the entire display lites. I can depress the cancel button and it resets the M/W but the problem persists. The problem seems to be progressive, i.e it happens more frequently and sooner as time goes on.
I have already replaced the control panel...did not solve prolem. All of the switches and TCO's appear to test good. My next thought is the control pad, however, I don't know how to test it.
Could not locate the tech sheet (isn't it normally in with the control panel?), which would probably help.
Thanks,
Chris

Check out the National Class Action Lawsuit filed against GE and Samsung for defective microwaves. Go to Home

Answers to questions underlined. Originally Posted by: MicrowaveDisplaycom  Just to clarify, does it run for 1-5 minutes, or actually just 1-5 seconds? It's in minutes. I am working on another (same model) with the same symptoms. The time it took to shut off decreased gradually until now it happens immediatelyThe difference is important. And you say it "shuts off and the entire display lites". How long between the time it stops running and the moment the entire display lights up? The display lites up immediatley (displays 888888) Is it immediate, or does it take a few minutes after the shut off for the display to come on? The display lites up with al 8's (8888888) immediatley. When you press the the reset/cancel button the 8's go away and you can operate teh touch pad normally.Is the internal cooling fan running? When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually. If you are talking about the fan that cools the magnetron....yes it comes on when the machine is running and stops when the machine shuts off.I'm instead talking about the internal fan which comes on automatically whenever you microwave. We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here. Once we get these answers, we can offer more specific advice. Thanks, Chris

I've been doing some research. Could the problem be the HV Cap or the magnetron??
Hpw do I test the magnetron?

I’m having the same issue. But i think it’s the cooling fan for the magnetron. Without it, the magnetron overheats and that is what is shutting the microwave down.
