Microwave sparking.

[Riejufixing]

Sparks sometimes come from the screws holding the three wheels onto the microwave plate, to the floor of the microwave, when I'm warming something like flour for breadmaking. The wheels themselves appear a little greasy/grubby, could that be why? I am going to clean them and see if that helps.

I put a plate with gold edging in a microwave once. When I saw the sparks I realised what I'd done, won't do that again

New microwave? old? coating come off something?
If you can't put metal in a microwave, why are they made of metal inside?

So many questions...

Are there any 5g antenna nearby?

Have you tried putting a CD in there shiny side up and then turning the microwave on?

[Ribenapigeon]

Have you tried putting a little fat IT technician in?

Each CD can be played once in your microwave and it will only play for a few seconds.

A butter wrapper plays better than a CD. IMHO.

OP is your Google running in Lock-Down mode?

Either the wheels and plate support have some conductive material splodged over them or the track is worn through to bare metal.

The metal microwave ovens is made from is bent in shapes that don't collect the micro waves so do notnspark.
The mesh in the door window is a Far away Cage. Waves are dissipated.

Boring reply; microwaves rely on water content to heat things up; I imagine flour has a very low water content so maybe it struggles to deal with this? I find that if I use warm water my dough comes out at a good temperature even though our house is pretty chilly. If you’re really desperate could you warm flour in a saucepan over a very gentle heat and stir continuously? It wouldn’t burn and would warm through easily

Bare exposed metal will spark. As already mentioned, the wheels wear the paint off in a ring shape or their own paint off if metal, exposing bare metal, creating sparks.

I used to work as a chef years ago. I came in one morning to find the old lady who cooked the breakfasts, using the new £4000 industrial microwave to cook bacon on a metal tray! She’d never used a microwave before.

It was like a serious lightning storm going on in there.

Have you tried microwaving a single grape that is almost, but not completely cut in half then laid flat on the cut edges?

You can put metal in a microwave quite safely as long as it doesn't have any pointy bits or narrow edges. It's these that cause the problems as they act as antennae and cause standing waves that can cause the magnetron to overheat. Put a ball bearing in and nothing's going to happen.

Exposed screws shouldn't cause a problem either - the manufacturers put them in there after all. If you're worried just put a bit of paint over them - but let it dry before you fire it up again.

Virtually every microwave I've had has had something similar come with it.

That's my first combi one.

How does a microwave oven become 'metal friendly'. Are the microwaves different in some way? Purple rather than red?

Microwaves are outside the visible range of the EM spectrum, so no colour.

Much like 5G.....

[Nobby the Bastard]

So your refusal to accept that other people could possibly be right continues?

You really are a fucking twat!
