No heat
display, turn table, fan, light all working.
when running it makes louder than normal sound
In this case I would suspect a bad high-voltage recitifer diode or magnetron (due to the louder sound) but...
Generally, the most common causes of a failure to heat are:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part
