The customer reported that their refrigerator wasn't cooling properly. We identified a defrost system malfunction that was preventing the unit from maintaining temperature. Job complete. The technician inspected the defrost heater and sensors, determining that the defrost cycle was not operating correctly, which was restricting proper airflow and cooling function throughout the unit.

The customer's ice maker wasn't producing ice because it had been turned off. We turned it back on, verified there were no error codes in the system, and cycled the ice maker to confirm it was calling for water and operating properly. Job complete. Technician cycled the ice maker and verified normal operation with water inlet valve response. No fault codes were present in the system diagnostics.

The customer reported that their LG microwave wasn't heating food. We tested the unit and found that the magnetron and high-voltage diode had failed. We replaced both components and verified the microwave is now heating properly. Job complete. Technician diagnosed a failed magnetron and high-voltage diode (OEM part 6851W1A002E) by measuring amperage draw at 6 amps and performing standard microwave heating circuit diagnostics. Both components were replaced to restore proper operation.

The customer reported their refrigerator beeping and the fresh food section not maintaining a consistent temperature. We diagnosed a freezer fan feedback error and found moisture corrosion on the ice paddle affecting the display control board. We replaced the user interface to restore proper temperature control and stop the beeping. Job complete. Technician connected to the appliance's network diagnostic interface and retrieved a freezer fan missing feedback error code. We tested fan control and feedback signal response, inspected the ice paddle for moisture corrosion, and replaced the WR55X35746 control board (touch pad assembly) to resolve the display beeping and temperature inconsistency.

The customer reported ice buildup in the freezer's ice maker. We diagnosed ice chunks stuck in the mold and tested the ice maker thermistors, motor function, and water valve—all operating normally. We replaced the ice maker assembly to resolve the issue. Job complete. Technician performed diagnostic testing on ice maker thermistors and verified full revolution operation and water valve cycling. Ice maker was replaced and customer was advised to allow 24 hours for ice production resumption.
