Constant beeping ...Kitchen aid microwave/convection?

I know I am not the only one to have this happen...it happened already once about a year ago and the service tech didn't really have a clue as to what was causing it. He did however replace the electronic pad assembly...$589 (thankfully under warranty) but here we go again...beep beep beep beep and randomly changes display readings. Sometimes it actually works though...briefly. then...beep beep beep
what the hell is going??? DO i NEED AN EXORCIST??? This microwave sucks TV dinners in Hell//
Any ideas? Kitchen aid doesn't seem to have any... and this appears to be a common problem.
