Microwave power,timer seems to work but it does not do anything.

It sounds like a 'Friday afternoon special'.

Reviews mention 'design issues'. Perhaps contact GE direct

You are brave working inside a microwave oven, you must be an electrician or electronics engineer. This is my normal advice

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.

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.

Hello

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

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.

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.

Sincerely Steve

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: http://www.fixya.com/support/t267796-kenmore_microwave_hood_combination_over

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.
