There is no "unusual" buzzing sound to suggest that. Is there a chance that there's a bad wire contact?
IF IT WERE the magnetron, would it have that BURNT RUBBER smell?--do magnetrons EVEN HAVE wires that could burn?--I would like to know this BEFORE I upen it up.--If the magnetron has ANY wires that burn when it's NO LONGER working, this will give me THE BEST clues.
You've been great so far, I just don't get the why the BURNT RUBBER SMELL if it were the magnetron.
OK. if you somehow determined that it may be something else (due to the burnt rubber/wire smell), please let me know. my email address is XXXXX@XXXXXX.XXX.
I personally think it's something else as you may have noticed but will still "accept answer" to close the file and will proceeds to look for other suggestions.
Thank you and happy new year.
