Unit not turning lights on. I found broken door switch causing issue. Removed and replaced door switch. All tests good.

"Removed and replaced capacitor, main control and harness. Tested unit. All tests good."

New construction. Unit not heating and making noise. I found that when unit was installed pieces of cabinet got into fan blade of blower and caused noise and fan to stop causing no heat. I removed blower and cleared fan. All tests good.

Resident is concerned with metal on metal sound when cycle is started and stops and when vent fan is turned on or off. Sound is coming from vent flap in building venting at top of microwave. When the magnetron comes on the fan motor starts which blows the metal flap open. When the blower turns off the flap falls from gravity. The sound is the metal flap opening and closing. There is no repair to stop sound as this is normal operation for this venting setup. Every house venting is different and can cause different levels of sound. If the unit was to not make the sound I would suspect the flap being stuck in vent which would cause issues for long cook cycles. Microwave is installed correctly. All tests good.

Removed and replaced compressor per service pointer. I vacuumed system down and charged with 48g R600. Tested unit. All tests good. Sealed system complete.
