My otr microwave is about 10-15 years old Hotpoint counter saver. It suddenly stopped working the other day. It appears that all the controls are working and the power is on but things do not heat up in any mode. Do I need to get a new one?

Re: microwave power,timer seems to work but it does not...

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and

My two year old Frigidaire Microwave suddenly stopped cooking. All of the buttons work. The lights, the fan, the timer, and even the cooking timer operate. It's just that the light goes on and the timer...

Check the plug. If the vault is 110v or 220v etc.

If the plug seems to be right, but still not
working, you should buy a new one
with a good name brand you can trust.
It's better than paying for repairs and future repairs.

Can I replace a 1.3 cu ft otr microwave with a 1.5

Brackets can remain the same throughout a particular brand for several years but will also change every year at times. Same year and same brand, I would say yes. Different year of manufacture or different brand name I would say, no it will not fit the existing brackets. If you have a particular brand in mind and have the model number of the existing OTR, it is usually possible to search out installation instructions for both at the manufacturer's website. You could then compare to see if they will match up. The two screws through the upper cabinet floor into thr top of the OTR can vary, within a particular brand even in the same year of manufacturer.

My 4yr old NN-S262SF OTR runs for 2secs and stops whenever start


Microwaves use alot of power and should be on their own 20amp circuit. Get an electrician to put the microwave on its own circuit.

OTR Amana microwave- No power, lights, clock or sounds.

Either your magnetron, cooling fan, or the magnetron thermostat is failing.

Since it's less than one year old, it would be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

Amana / Whirlpool customer service is here.

Please contact them to find your nearest authorized service center.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Hotpoint Counter Saver Microwave not working

Please do not try to service. its dangerous to play with the internal parts of a Micro Wave. Most counter tops are pretty inexpensive buy a new one if the warranty is out.

GE microwave oven

Does the turntable rotate? If everything but this works (except no heat), you probably have a bad door switch. Here's a discussion of what's involved in replacing it:

If the turntable does rotate, I'd suspect a more significant failure, such as the transformer, capacitor, or magnetron. If it's any of these, it's time to replace the unit.
