We have a Kenmore Microwave (Over the Range) #790-80322310, after its 1st use we were ready to take it back due to the constant repeating of its 'buzzer' signaling when the cook cycle was finished... Our question, can this buzzer be modified or simply disconnected without causing any problems elsewhere. I am a very familiar & qualified repair tech with many yrs. in industry maintenance. Thanks in advance for any solutions that will quiet the mind-of-its-own buzzer!
