Question about Microwave Ovens

Sharp R 530DK 1200 Watts Microwave Oven won't cook

This microwave has been in storage for about 3 years. Used for about 6 months since new and worked perfectly when I repacked it in it's original packaging and box. To my knowledge it was not dropped.

All of the electronics seem to work (set clock, timers, start, etc.) and the timers count down as though the microwave was on but the oven does not come on nor does the carousel turn.

I have unplugged and replugged a couple of times. Any ideas?

Thank you.

Good for you for doing the cold reset. Good job!

Hopefully it was not stored in a damp or unheated area, since that can case damage that will complicate the diagnosis.

But 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
disassembly information at our site, linked here on Fixya:

My microwave stopped working you can input time but when you push start nothing happens it has power and everything just will not start its like the start button does not work

Possibly a bad door switch behind the holes where the latch hooks go into. Usually with the bad switch the timer counts down but nothing runs. It all depends on which switch is bad. Usually 3 switches inside.

Sharp Carousel R530BK microwave won't cook unless light pressure is kept on the door button.

There are door switches and one of them is evidently out of adjustment or the little actuator arm on it is.

At least twice in the past month have had food explode all over the microwave (as if it was overheating). Items vented properly or not covered at all. this time, kept making poppong noises for at lesat 10...

If you have an item overheating, try looking at the directions on the unit for the watts and adjust cooking time according to the oven. Some foods will explode if left for too long in a quick heating microwave oven. If this is a new problem and the microwave is 4 years old, you may consider the unit is beyond its useful life. Its difficult to tell w/o knowing the brand, but it could be the meagtron tube is simply wearing/worn out. Let me know if this helps. m
