Hi Gerald!

Any suggestions appreciated as I hate the idea of tossing such a GO> large item to the trash escpecially when it could be something simple to GO> fix.
Well, as (one of the) Mark Ransley said, snipping the wire to the 'beeper' would certainly stop the beeping! May be easier to put a piece of Scotch tape over the beeper - I did this when I was working on a computer with the cover off and had to reboot it numerous times to find the problem. Amazing how a piece of tape over speaker cuts the volume!
Anyway, back to what's causing the microwave to beep. How old is the unit? I'm thinking if it's 12-15 years old a capacitor could be leaking causing a staticly signal to be created which the logic circuits interpret as "time to beep!".
Could also be some noise on the AC line causing the same thing. Any X-10-type devices or other devices using the AC lines for carrier? May be outside of your home ==> adjacent neighbours on the same power feed as your home.
There used to be "AC filters" available; not sure if they still are. I have an old two-prong one which Dad bought ages ago because of noise on the stereo (RF interference).
