72166993011 Kenmore Microwave - Instructions

Ordered the switches from Partselect, arrive in two days. Had trouble removing the plastic connectors from the old switch terminals, one of the plastic protectors broke, but was able to reuse it. It took a little figuring out how to remove the existing switches. Must push in a tab and rotate the switch on a little pin, then remove. Must be careful not to break the plastic tabs holding the switches in place. Replaced all (3) switches at the same time. All in all it was pretty easy.

Problem was due to a faulty door switch. Replaced with a new switch and the microwave now works fine! Only thing that was tricky was that LG uses the hex screws with a peg in the middle to keep the microwave cover on. Had to use a small screwdriver and pliers (on the screwdriver) to unscrew the screws.

I had previously replaced the turntable motor, which helped for a small while. When the problem occurred again I examined the turntable assembly (small wheels which support the glass tray as it turns). The wheels were all flat on two sides. It may have been a defect from the beginning or a result of our placing food off-center because this model has a terrible cold spot in the middle of the microwave pattern................ The repair was as simple as taking out the glass tray, pulling the assembly (plastic arms with wheels on the end) off, dropping the new assembly on, and replacing the glass tray.............. This is surely worth a first look before replacing the turntable motor.

Partselect sent me the right thing in two days! The whole process was easy as pie.

unplug the unit then pull down , lot of screws are on top. open the cover . you could see the parts that need to replace on the right hand side (heavy side). disconnect wires then test the parts that need to replace by a tester to make sure that it's really broke .then unscrew part and replace .
