Assuming your inside light and turntable come on when you try to microwave, with the symptoms you have, I would most strongly suspect a bad magnetron or a loose and possibly corroded connection on the magnetron's terminal.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

(if it's not shorted or burned, it'sprobably okay)

The best place to order parts for this brand is Encompass (formerly Tritronics).

Or you can call them toll-free at 866-779-5835.

How to fix loud hum and no heating in Sharp model R-308KW?


Hi,
There could be a variety of reasons why this happens, but the likeliest
reason is the secondary interlock or monitor switch is broken. These are micro switches that tell the microwave that the door is closed. If this switch is broken, then the microwave thinks the door is still open and the carousel table won't turn, and the oven will not heat up.
I replaced an interlock switch last Saturday. The switch was $7.00 and took me an hour.
Ask your local repair person to test the interlock and monitor switches first, then go from there.
Good luck,
Hank

Motor 'Dragging'


The motor run's the same speed regardless of power setting.

If 1000 wats is too much for your poor old electric service, then you better not use your A/C.

As for checking voltage, you need to measure the voltage at the plug with the microwave operating.

Sanjay
This is due to the magnatron failing (this is the part of oven that cooks the food!) This is the most likely cause of y isssour oven not heating the food!

Magnatron needs replaced for oven to work again!

Can't pop popcorn well


It's 850 Watts, 0.9 cu ft.

That's enough for popcorn, but a magnetron does lose power once it starts to age.

The figure I've heard is an average life expectancy of 2000 hours for a magnetron.

Two "Band-Aid" suggestions for better exposure and more even heating:

1. Place the popcorn bag on top of an upside-down paper plate.

2. Place the bag off-center instead of dead center. Placing food in the center of the turntable is not as efficient as placing it off-center.
