I have a new microwave MSE 23 i bought it 1 month ago. It has been working fine maybe use it 6 times a week. I put jacket potatoes in tonight when i went to get them out they had not cooked but felt warmish.Tried a few more times to no avail. Can you help.

Sounds like MW has failed. given the age of unit repair is not economically feasible. I would buy a new unit and forget it.

Older microwaves can develop any number of quirks.
Instead I suggest calculate the number of cooking time minutes needed and use that for your potato.
Be sure to fork a few holes into the skin of the potato so it doesn't "blow" and redecorate the inside of your micro.

If purchased "new" 6 months ago, it should still be under warranty. Call repair service....

Is the internal cooling fan working?

Are the ducts and vents clear?

Problems with any of those can result in overheating, which destroys magnetrons.

I have seen high voltage rectifier diodes interact with magnetron in funny ways. I'd replace the diode, too.

You can find links to helpful exploded view diagrams and part ordering help here.

I recommend that you bookmark that link to your favorites.

Finally, baking potatoes and making popcorn really give the magnetron a workout.

You should put about 1/2 cup of water in the rear corner of the microwave when cooking those foods.

It helps "preload" the oven to prevent execessive microwave energy reflection back to the magnetron.

I had that issue and I opened the unit and there was a fuse near where the power went in. Went to the small local hardware store and they ordered it. It was well under $5 (can't remember) but it still works over 10 years later.
If the fuse blew again I would have trashed the unit.

one of three things shorted could cause this: H.V. diode,capacitor,or the magnetron tube, take screw driver and short terminals on capacitor before touching anything inside the case, then chk resistance on capacitor should show infinite after needle settles, diode should show hi resistance one way and a lower resistance in the other direction(use the RX100 scale not the RX1) on both parts diode should not show very low resistance or it could be leaking,mag is a different story,it can be chk'd but in a different way

If the supply voltage is low it will take long time to heat foods. The second reason is the Magnetron. Since it is in the warranty period you can call at the sharp authorised service center. They will do it free of coast.

if your keypads dont work maybe the cushion or spring beneath is worn, so check your dealer with your warranty documents so you can get it exchanged

After washing you need to poke holes in potatoe skins or the steam can cause them to explode. Cook potatoes no longer than 6 to 8 minutes depending on your units power.

Microwave ovens can be very dangerous if damaged, so you will be safer to replace the unit. Better safe than sorry. Service on microwave ovens is not cost effective, and the newer ovens are very reasonable.

It should default to the high power level without your having to select that.

But if you think it may have a problem, you could unplug it for a few minutes then plug it back in and try again.

After that, if it's not acting as it should according to the owner's manual, it may need service.

If so, since it's under warranty, I would let GE fix it.GE Customer Service is online here.
