Question about Microwave Ovens
Everything works bar the microwave function. you set time and it sounds like its working but there is no heat transfer and it terminates the function short of the set time
Sounds like the microwave unit (magnatron) has failed. This will happen if the microwave has ever been used without anything in there to absorb the energy. It basically cooks itself.
Unless you are particularly fond of this unit, it is usually cheaper to buy a replacement than order parts and repair.
You could phone a few local repair centres and ask for a quote , but weigh this against the next thing likely to fail.
Worth repairing industrial models, not really worth repair to domestic models.
Hope this helps you.

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.
