Re: microwave oven not working model sharp R-38ST

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 dcs mo-24-Ss microwave oven cannot heat the food after turn on, everything working fine other than no microwave come out

Assuming the turntable, inside light, and internal cooling fan all work when you press "Start" to cook, then I would suspect a bad magnetron, or a bad connection at the "FA" terminal of the magnetron.

If one or more of those three items do not work when you hit "Start", the I would suspect a bad door switch or mount.

The DCS MO24SS is essentially a rebranded Sharp R-530E-series microwave with different cosmetics and a higher price.

The service manual for the Sharp model is here.

The internal Sharp parts in the manual will interchange, but not the external cosmetic parts.

You can order Sharp parts from Encompass here.

Microwave not heating up

Check the door switch, when it is faulty the oven will turn on but turntable, fan and magnetron wont operate.
