Knowing nothing about microwaves if it was mine, I'd open the back, look for any fuses that might have popped. It worked for me once many years ago   

ive had that with my sisters,it was a big fuse insude and cost about £5.it fixed it and ran for a few more years

Either way, there is many KV of DC around that bit so watch your fingers!

That's why I said it was far too scary for me, earlier I've had quite enough (relatively harmless) belts off the HT systems in CRTs.. and cars.. and.. well, anywhere you can find an HT system, really.. enough to put me off playing with things like microwaves!

So a fair warning to Opti

The magnetron voltages and currents can only be described as the most potentialy lethal electrical supply you have in the home

"Magnetron"

Anyone else thinking of Woody Allen`s: Sleeper[/i]?

......much hilarity and giggles here!

Orgasmatron perhaps, Ms Debs....

I'm definitely never opening mine if it stops working.. Opti is a braver man than I if he wants to poke around in one!

That's your roof, your gas regulator, your telly and now your microwave oven. You're a rather Jonah mate.

Yep. I reckon it could be something as simple as that, Andy. I'll test it out on the poodle next door, just to make absolutely sure that it's Donald Ducked.... .

I'd try it out on your mole Opti, you won't upset the neighbours!!

Also not unknown for one of the (several) interlock switches that prevent operation with the door open to go out of adjustment or fail, ditto a thermal cutout switch. Sometimes there's a fuse or two. (If the fuse is on the HT side of the transformer, replace it with a suitable type of high voltage fuse).

But, often, as said, the diode and capacitor are a bit marginally rated or poor quality and they go pop.

Parts are readily available on Ebay, just be careful, as said. They can thoroughly ruin your day.

I'm not sure it'll be a door switch.....otherwise the grill/oven wouldnt work.

I know mines a different make , but mine turns everything off grill/oven/microwave if the door is open...(or it thinks it is....a door switch is slightly out of alignment)

I must be braver than you as well then  I've had mine in bits several times......all perfectly safe if its not plugged in!

Not like CRTs, then.. every belt I've had from them, they've been unplugged (sometimes for a while)

Screen acts as a capacitor working at some pretty huge voltages so that's not surprising really. You're supposed to discharge em before playing.

[Marks DTM Calib]

Bugger all current in a TV HT supply though.

Magnetron anode voltages are 3-5KV and if its a 900W input power oven then your talking a merry 300mA + and a stonking great big capacitor to store a laod of charge to........all orders of magniture greater than a CRT setup.

But still, not hard to diag and work on (read about as simple a circuit as you can get!), just either leave it off for a day or so or discharge the cap with a suitable resistor.

So they can give you a pisser even when disconnected?.....

Buy another one Opti. Seriously!

Keep an eye one the Aldi and Lidl websites for special offers on microwaves you can pick up a decent one for less than fifty quid, they also come with a three year Guarantee based on that it's not worth messing about trying to repair  your old one by the time you take into consideration the cost of parts time etc, and the fact you can "get a hell of a belt off that "
