A repair would never be economical on parts alone, forget the labour.

Our microwave packed up last year and our first thoughts were to rush
out and grab another. But we've found we've coped pretty well without
one. Plus I never liked standing near the bloody thing when it was on.

It depends on the quality.
A 30 quid basic microwave you'd be insane to repair.

A 270 quid 40l convection oven/grill/microwave stainless one, possibly not.
I've at the moment got a 27 quid PCB for the oven arriving, to repair it.
ENSURE THAT YOU KNOW WHAT YOU ARE DOING BEFORE OPENING A MICROWAVE, THEY ARE
THE MOST LETHAL DOMESTIC APPLIANCE TO REPAIR.
