Question about Microwave Ovens
When using microwave I felt something like a buzzing while pressing the button to open door. A fuse blew in main wall panel. Replaced blown fuse and micro worked a bit more and then same thing happened while pressing button to open door. This time micro is DEAD - not even a light working. My computer is on same circuit and is back up and running. I've been reading a number of other problems and solutions that seem similar and I wonder if there is a fuse in this model as well. Dunno if I should invest in repair or just buy new one. Won't be able to afford another combo with convection if I buy new so would rather get this one fixed if possible. Thanks in advance to all you fantastic techs that are willing to offer advice.
You are decribing a typical Door Safety Switch problem. The Door Safety Switches has Failed.The Door Safety Switch is designed to shut down the Micro in the event the Micro is still cooking when the door is being opened. The first "Click" of the switch cuts off the "Cook". If it does not cut off the "Cook", the second "Click" blows the power. Otherwise it would "Cook" with the door open, and I need not to tell you how DANGEROUS that could be. It first Tripped the Circuit Breaker which supplies power to the Microwave. After Re-Setting the Breaker the same thing happened except this time the Micro is DEAD- not even a light working. Yes, there is a line FUSE inside the Micro. You however need to address the Door Switch SHORT before replacing the fuse. If not, it will just Blow The Fuse Again, and Again, until the Short is corrected.
Call around, ask How much to replace a Door Safety Switch.
