Sharp Microwave Does not Heat

All digital works, clock counts down but no rotation or heat

I would most suspect a shorted high voltage rectifier diode, a bad connection on the FA terminal of the magnetron, or a bad magnetron.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

You can usually find exploded views and order parts by entering your model number here at the Sears parts site.

The best place to order Sharp parts is Tritronics.

There are a few things that will cause this problem, the high voltage diode, or the high voltage capacitor, and the magnetron are usually the culprits. I find that one or more of these parts will go making the cost to repair at least $100.00 and up.

Probably a bad door switch. See this file.

Sounds like the Magnetron has stopped working. The Magnetron is is a specially designed powerful magnet that generates the high frequency microwave energy used to heat food.

It's probably a loose connection at the magnetron or a bad magnetron.

If it's less than one year old, it should be fully covered under warranty.
I'd suggest contacting the manufacturer to get it fixed free.

If
it's within the magnetron portion of the warranty (usually 5-9 years)
but out of the original full warranty (usually 1 year), then your
manufacturer will cover the part cost, but not the cost to visit you or
the labor charge to do the work.

Some manufacturers (in the US anyway) will send you the magnetron to do it yourself. If
nothing else, you can save about $75US by taking it to the shop yourself.

Apparently you're in the UK, judging by the model number.
