    if the magnetron coil is not working and the unit is at least 6-7 years old..what do i do? is it replaceable? and how do i confirm it is the magnetron coil? is there a way to check it. The previous answer did not seem to offer any solutions. Hope i'll get one that could take me through steps to figure out what's actually going on. thanks.

With the symptoms youhave, I would think the problem is either a shorted high voltage rectifierdiode or a bad magnetron.

The diode is acheap fix but the mag will cost more and is more complicated to replace.

Hi
The first thing to try is a "hard reset". Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

Let me know if the hard reset doesn't fix it and please reply back .......

When themicrowave sounds okay, but there's no heat, one of the internal doorswitches, the high voltage circuitry, or the circuit board may have aproblem. To resolve this problem, you need the assistance of aqualified appliance repair technician.

You can inspect the door switches at home.

My samsung microwave oven is not heating up food. It works normally, lights on, food turning on plate, but not heating the food.


if your microwave does everything you have described , and you can hear the cooling fan running as well after you press the start button , you probably have a faulty wave guide. The wave guide is also called a Magnetron Tube. It is the main part of the microwave which produces the microwave energy . If this part is not functioning it is best to replace the entire unit, rather than have it repaired .

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.

You order Sharp parts Encompass here or call them toll-free at 866-779-5835.

> Will the food be evenly heated even though the plate is not rotating?

No.

Food won't heat up


Hello, I had the same problem, and just fixed mine. Start by turning on your microwave (on mine, the light turned on and timer worked, but the fan nor the plate turned)... push the door upward and see if the microwave turns on... (mine did). so far so good. open the door and take the upper hinge cap off with flat head screwdrive. take the door off and place a small washer on the bottom hinge, put the door back on. your microwave should be good now. essentially, the door just needs to be pushed up a bit so it will work.
good luck, hope that works for you...

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

You can see and hear 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 is a pretty simple job.

You need to unplug power, then remove the bottom cover of the oven.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
