Micrwave oven

I have a Samsung M1714 Microwave that has stopped working. It appears to operate ok but there is no heating. Although I have been involved with electronics all my life, I know very little about microwave ovens but I decided to have a quick check. I found a glass fuse - contained within a plastic holder - that is open circuit - 11/4 inch, 0.75 Amp and rated at

5kV. In series with this is a diode - HVR 1X 3 - that reads short circuit. Would replacing these be likely to solve the problem, or is it probable that there is something else - anyone got any any ideas/advice?

Replacing the HV diode and fuse may fix it unless something else caused the diode to short. It's worth trying.

But, realize that microwave ovens are the MOST DANGEROUS home appilance to service so make sure you read and understand the SAFETY info at the site below.

Many thanks, yes I am aware of the inherent dangers of microwave ovens - and I am treating the thing with due respect! Does that HV diode need to be an exact replacement?

Generally, no. A 15 kV generic microwave oven diode should be fine assuming it's the typical half wave doubler circuit.

Go ahead and replace them, the diodes are only about 6 bucks, it'll probably work after that.
