Switches Off half way through a run and few mins later turns back On

Hi,

I am seeing a weird issue with my GE Microwave (http://products.geappliances.com/applian...).

Few days back it suddenly started turning off as soon as a cycle would complete and I would open the door. Few minutes later it would turn back on automatically but in reset mode i.e I had to set the clock before I could use it again.

Today, it went a step ahead. It now started turning Off few seconds into a cycle and then turns back On automatically a good 10+mins after.

My google search so far have not yielded anything useful. Closest I could get was to 'faulty door switch' but again description mentioned there does not really match with what I am seeing.

Any suggestions or pointers to diagnose the problem will be greatly helpful.

Thanks

Sri

Hi @sri_yj ,

Have you tried disconnecting the power completely for about 10 minutes to see if this "resets" the microwave?

I'm thinking that it may be either the control board or perhaps the control panel may be the problem.

Neither of which are cheap https://www.geapplianceparts.com/store/p...

Hi @jayeff,

Thanks a lot for your comment. I did exactly that, had unplugged it through yesterday night and connected it back this morning. Unfortunately, problem still persists.

Wow.. those parts are really expensive. Is there any way to confirm that it is indeed the control board/panel that is the problem here?

Hi @sri_yj ,

Without access to the service manual it would be very difficult.

Also mostly these days it is usually a case of installing a replacement part to see if it works and the faulty board is returned for repair or it could even be disposed of as it is cheaper to manufacture new boards than it is to find and fix the problems in faulty boards.

You could always check what the return policy is from the parts supplier and take a chance on getting the correct board the first time, if the price was OK that is to return it if it wasn't the right one. Just a thought.

If you do decide to do this, lookup "how to discharge a capacitor in a microwave oven" before you get to deep into the repair. Depending on your medical condition microwave ovens can still be lethal or give a nasty shock even if the power has been totally disconnected for days.
