Broken microwave - most likely needs a new magnetron

Hi,

Has anyone ever gotten a microwave repaired - specifically for a broken magnetron? The microwave appears to be working but doesn't actually heat anything up which is why I think it's the magnetron. Would it be as cheap to buy a new one?

afaik it's not economical

Thanks for the reply. Yeah considering there are decent-ish looking ones for about €50-70 in power city I might just get a new one.

it is more likely to be a faulty diode or even a fuse

I would doubt that the magnetron is gone - they are fairly robust - far more likely it's the circuit which drives it. For the kind of money you are looking at for a new one (€50-70), it's not really worth the time and parts trying to repair it IMHO.

Might be just a spade terminal!
I had one where the connection to the Magnetron was bad, one wire
had loosened = no power.

Just had to remake the connection & all was OK again.

While the price of a new one can make the cost of repair seem uneconomical, I'm sorry I ever replaced my old one. There was a dial to vary the wattage, (marked by wattage, not %, or high/med/low)so it was easy to follow any cooking instructions, whether the package said 3 minutes at 800 watts or 4 minutes at 750 watts, I could set it directly without guess work or getting the calculator out.
So if you were happy with the old one, it might be worth the cost of repair.
