This is a sure sign that the MAGNATRON needs replaced (this is what heats up the food) if every thing else works but food not cooking! 99% of time it is the magnatron!
Please rate answer!

Microwave model MV-1510M is not heating, also sounds louder. Everything else is working, fan, lights, turntable etc..


If everything is working normally, except for heating, the likely cause is the magnetron.  Microwaves can be dangerous to work on, as the site below points out.  If you have an ohmmeter, it is possible to check the magnetron, but be certain to follow the precautions outlined at the webpage:

Doesn't heat anything


It sounds like the micro generator has died.

Yes, you should buy a new one as the cost of repair is likely to be high.

My Russell Hobbs microwave will not generate heat


If everything else is normal, the trouble may be a failed magnetron tube (the microwave source), problems on the control circuit board, or parts in the tube power circuit that are bad. It's also possible a door switch can be at fault, but this usually keeps something else (fan, turntable or light, most often) from running as well.

Microwave servicing is best left to professionals. There are potentially deadly voltages present, and a chance of microwave leakage if repairs aren't done correctly. Take the oven to a shop for an estimate, or just consider replacing it if it isn't a built-in, an over the range unit or a high-end countertop model.

Won't heat and turntable doesn't turn


In all likelihood the mangnetron has failed, or perhaps even something in the Power Supply. or a fault that is shutting the system mangnetron down, for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

Microwave turntable doesn't turn. Everything else


The turntable system typically consists of the motor, the coupler, the turntable support with rollers, and the tray.

Here is a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

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

But if you've recently had trouble with the cooktop lights, then the control board may be damaged.

We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in about a week or so with a one-year guarantee.

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

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.
