Our microwave tripped the household fuse box, and after checking and replacing the microwave plug fuse as a precaution, the microwave works but does not heat. Everything else works fine including the grill. Is this an economical repair? Many thanks
See the informaton with carefully and use the common sense:
God bless you
When
the microwave sounds okay, but there's no heat, one of the internal
door switches, the high voltage circuitry, or the circuit board may have
a problem.

That would be a UK model. No wonder I had so much trouble finding it.

SOURCE: Microwave runs when door open
This is probably a a bad door switch or door switch mount. Chances are only the fan and light are running when you open it, but better safe than sorry. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure but not the only one. I have a text file called "doorsw.txt" which helps in diagnosing and repairing door switch problems, and a file called "safety.txt" which is of vital importance. You can find these files by searching at Yahoo.com (not Google) for this: microwave display safety.txt If you still have a problem, please write back with more detail. Be safe!
SOURCE: microwave blows fuse in microwave mode grill function ok
It is most likely the capacitor has shorted or the rectifier has shorted. Check with ohmeter, but make sure it is discharged first by shorting the capacitor with a wire.
SOURCE: Can you tell me where
Because I do not know the exact Model number of your Microwave Go Here and enter your model number to get the Owners Manual.
