Thermostat failure can occur due to wear and tear, electrical issues, or damage. If the thermostat fails, it can result in temperature inconsistencies, such as the oven not reaching the desired temperature or overheating. This can lead to uneven cooking, undercooking, or burning of food. Before beginning this repair, disconnect the oven from the power source to avoid electrical hazards Locate the thermostat and carefully disconnect the wires connected to it. It is advisable to take a picture or label the wires to ensure proper reconnection later. Gently pull out the thermostat from its housing and position the new thermostat in place. Reattach the wires to the corresponding terminals on the new thermostat.

Part #4681W1N002B
This convection fan motor is designed for use within various models of ranges/ovens and is a genuine OEM part. It heats the inside of the appliance through the use of a fan and the airflow it creates. This fan motor comes as an individual part without the attaching fan or hardware to secure it. If you hear scraping and scratching noises coming from the fan assembly at the rear of the range, or if the fan is not rotating, this motor is likely damaged or worn-out and in need of replacement. Failure to do so will result in poor heating throughout your range and generally poor performance throughout. To replace this fan motor, you will need a screwdriver and wrench and will need to first disconnect your range from power. Then you can pull the range out from the wall and remove its rear panel. Disconnect the wires connected to the fan motor terminals and remove the securing hardware for the fan motor, which can now be replaced with the new fan motor. Reassemble the rest of the rear panel and connect your range back to power and test the fan motor.

Initial failure of over range microwave Aug 3rd. Control Panel worked but no heat. Took to local LG authoriaed local repair place. They fixed it quickly and we re-installed it. Worked fine for 2 months then had similar failure again. Agaim took to same authorized repairer. They kept unit for 3 months but finally concluded theu could not fix it and suggested we contact LG for a partial refund. When they tested the unit during re-assembly in my presence, there was a blue flash and the fuse blew. Since we had built a custom tile mural back splash around this unit, I brought it home, ordered a number of time delay fuses new capacitor and two new high voltage diodes. However, using my Fluke DMM, I checked the existing capacitor and high voltage diode and they checked OK so I just replaced the time delay fuse. The high voltage transformer leads had 2 possible ways to connect to capacitor and diode. Tried one way, plugged unit in and turned it on, and immediatly blew the fuse. Replaced the fuse and reversed the high voltage transformer connections,amd turned unit pn, and it worked perfectly. Since we had experienced several power failures during the time of the original failure, the repairer concluded that power spikes might be at fault, so I also purchased a TrippLite ISOBAR4ULTRA 3300 Joule surge protector between wall outlet and microwave, and re-installed over range. It has worked perfectly since.

We had made this determination with the help of a repairman on the phone. I ordered the part and waited for it. It was stuck in West Virginia. After several days after it was expected a repairman fixed my range to the tune of $168. It should have cost $30 (the cost of the part and shipping).
Unfortunately I probably won't order from PartSelect again.
