This sound like the Magnatron (this warms the food) has gone out and needs replaced! To be honest with you ,unless you can do this repair yourself it might be cheaper to buy a new oven
I hope I was of help!

Sounds like the inverter (power supply for cooking) or the magnatron which does the work----neither are cheap parts.

The keypad works; the microwave can be turned on and turntable turns round, the light is on, the motor sounds (a little louder than normal) but no heat can be generated. What could be causing this?

No heat would mean the magnetron circuit has failed. It's the part that generates the microwaves that heat the food. If it is making a loud buzzing noise, it could mean that the magnetron or the high voltage diode has failed. Since there exists high voltages inside the oven, would require a qualified service person to repair. However, if the magnetron has failed, would recommend buying a new oven since the parts alone can cost as much as a new oven.

I hv a 24ltr Sharp Carasoul Microwave. Few days back, its plate stopped working, but its heating the food fine. Why has the plate stopped rotating? Will the food be evenly heated even though the plate...

> Why has the plate stopped rotating?

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.

Microwave does not heat food

We have service manuals at our site which will help you:

Some questions to ask as you or someone you know checks it out.

When you try to microwave are the inside light, internal cooling fan and turntable all working?

If not, then it may be as simple as a door switch.

If so, then it may be a bad magnetron. It can be tested.

Is there any unusual noise or is it louder or quieter than normal?

A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound.

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are working.

You can order parts for this from Encompass here or call them toll-free at 866-779-5835.

Turns on but not heating food sounds a bit louder

Hi, this is common in most microwaves. this abnormal noise is coming from a faulty Magnetron. this device is responsible for the heating process and, it is damaged and not heating at all at this point.Simply replace the Magnetron and, this unit will start to heat once more.

Have GE JVM2050 over the range microwave, which stopped heating food and water since this morning. All other functions including light, key pad, clock, turntable work normal. The magnetron sound also

if everything works except the heating, it is most likely the mag tube is on its way out.........that is the most common reason for it not too cook.......since the microwave is a GE and it is 3.5 years old, i would say you are better off buying a new microwave, the mag tube starts at around $70.00 and up + the labor it costs too have a service person put it in........around another $60.00
