66993 (CSSESEA) LG Microwave - Instructions

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 .

I UNPLUGGED the microwave and removed the cover, using a phillips and a Torx screwdriver for the machine screws. I set these screws aside, so as not to confuse them with the later encountered screws. I photographed the magnetron to assure proper placement of the 6 phillips machine screws involved in reassembly (marking the the locations on the old magnetron would do as well. I marked the old magnetron "old", to avoid later confusion. I removed the two screws holding the shields to the magnetron. I removed 3 of the 4 screws holding the magnetron to the microwave, leaving one of the top screws. I held the magnetron securely and removed the last screw, pulling out a the part of the magnetron that penetrated the microwave. I installed the new magnetron in reverse order. One problem I encountered was locating one of the six screws, which had been pulled into the old magnetron by magnetism.

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.
