Ron for Model Number LMV2053SW A few days ago, the fan on our LG microwave suddenly started up continued to run and would not turn off even by pushing the switch. We had to unplug it before it would stop running. A few days later the unit would not heat. We unplugged it again and it worked OK again. Last night I heated up something in the unit and it seemed to work fine. Today however, the unit will not heat up, even water. Tried unplugging again but no success.
Answer Hello Ron, This is most likely a door switch. It is not recommended to replace only one since there are three and all of them will fail soon after the first one fails. You will either need one 3B73361E and two 3B73362F or you can replace the entire assembly as a unit by ordering part number 3501W1A019D. Read More...
