Microwave.

I have a Daewoo microwave, it starts, the turntable turns but it won'the heat anything up, can I fix it or is it for the skip?. Thanks, John.

I've just had my m/w fail for the very same thing, being a tad dangerous and not really understood I think when the magnatron goes it's game over, alternatively if you can find a local repair centre to fix it, labour costs would likely mean a replacement with fresh g/tee would be a more attractive proposition.

For the price of new ones now are they worth repairing.

Bin it - I wouldn't start playing with Microwaves personally......

I believe Lidl are selling cheap ones at the moment...

Agreed, there are some very high voltages in there, even when they are unplugged. Likely the magnetron, the HV transformer, or as simply as the fuse supplying the transformer - but lethal, if you don't know what you are doing.

THanks everyone, We are going shopping tomorrow for a new one. Thanks again. John.

Don't own a microwave ...one of those things I manage to live without.

Normally this is just a high voltage diode, the magnatrons don't pack up. If you are opening the back this will not break any seals as these are on the door. Use a mulitmeater and check to see if open circuit. You will see it, its a dirty great big diode. Don't run the microwave with the back removed. P.s you can get replacement s on flee bay but make sure it is rated for microwave use as the voltages are a lot higher than normal.

Its a Magnatron, developed by the British during the war for high frequency high resolution 10cm radar for night fighters.

The stored DC in there can be 2 to 4Kv, which is absolutely lethal. The caps are fitted with a discharge system, to allow the HV to safely leak away, but commonly these safety devices do fail. So I would never suggest the inexperienced delve into microwave ovens. Is it ever worth risking your life, for the £50 cost of replacing them, when you don't have much of a clue?

Me, personally I do, but then I am well aware of the risks and the precautions to take. Our present oven failed last year, so I dived in armed with a means of making sure the HV cap was fully discharged before starting to get too involved. As it happened, the fuse for the HV transformer had popped. Ten minutes later it was fixed from my fuse stock and at no cost. That was a £150 oven and well worth my effort to at least take a look.

We use a Toshiba that SWMBO brought back from Liberia in about 1980. Works perfectly and weighs a ton.
