This is a Whirlpool GH7208XRS-1, sorry I left off the brand.

It made it through the holidays and I am thankful for that, but today, while heating a cup of coffee, it just stopped. No internal lights. No display. No exhaust fan or lights for the stove.

It acted as if a fuse had just blown. I checked the circuit breaker. no problem. I checked the outlet; there is power. I ran an extension to a known working outlet; nothing.

It would appear that some main power supply has failed or become disconnected in some way or some internal fuse has blown.

This unit is under an extended warranty and is too heavy for me to remove from the wall, if that is necessary for servicing (they usually send two servicers to work on it). If it is an easily accessible part I could replace, I would be happy to try, but if it involves major surgery, I will call repair.

Any thoughts? Are there any simple things I could check without removing it from the wall mounts?

Thanks.
