Parts for Lg LSU122CE: Room A / C Parts

This electric appliance capacitor helps the motor start and run smoothly by storing and releasing energy when needed. Replacing a failing capacitor restores reliable motor operation and can stop intermittent starts or motor humming. What it does:

• Provides the electrical boost motors need to start and maintain normal operation
• Commonly used on compressor or drive motors in household appliances
• Symptoms of a failing capacitor: humming motors, slow or no start, intermittent operation, or frequent tripping
• Matches OEM function and mounting for direct replacement when the part number aligns

• One electric appliance capacitor

• Always disconnect power at the breaker or unplug the appliance before servicing
• Capacitors can hold charge—discharge safely and use insulated tools
• Verify replacement part number and terminal orientation before installation

Replacement electric motor used in select LG appliances to restore motor-driven functions. Replaces failed or noisy motors to help return normal operation, reduce unusual noise, and restore rotation or airflow where applicable. What it does:

• Provides rotational power to drive appliance components such as drums, impellers or agitators.
• Common symptom indicators: appliance won't rotate, motor hums but won't start, excessive grinding/vibration, or noticeably reduced airflow.
• Re-establishes mechanical motion when the original motor has failed or developed bearing/windings issues.
• Connects to the existing wiring harness and mounts in the original motor bracket.

• Disconnect power before servicing; verify the appliance is fully de-energized.
• Label or photograph wiring and harness connectors before disconnecting to ensure correct re-assembly.
• Use appropriate tools and secure all fasteners; inspect related components (belts, mounts, ducting) during replacement.

This isolator routes microwave energy between the magnetron and waveguide to help protect components and maintain consistent heating performance. Replacing a failed isolator can restore reliable cooking and help prevent further high-voltage damage. What it does:

• Directs RF energy from the magnetron into the waveguide/cavity
• Helps protect the magnetron by reducing reflected energy
• Aids in preventing arcing or burn damage in the waveguide area
• Common symptoms of failure: no heat or uneven heating, loud humming/buzzing, visible arcing/burn marks near the waveguide

• 1 isolator

• Disconnect power and discharge the high-voltage capacitor before servicing; risk of electric shock
• Handle waveguide components carefully; avoid contaminating RF surfaces and note exact orientation
• Take photos of the original setup to match positioning and fastener locations

This fan propeller assembly circulates cold air inside the refrigerator to help maintain even temperatures and proper airflow. Replacing a worn or broken propeller restores circulation and can stop abnormal noises. What it does:

• Moves air across the evaporator and throughout the fresh-food compartment for consistent cooling
• Restores airflow reduced by cracked or missing blades
• Stops scraping, rattling, or high-pitched fan noises caused by damaged propeller blades
• Helps prevent uneven cooling and localized warm spots when operating correctly

• One fan propeller assembly

• Unplug the appliance before starting any repair to avoid electrical shock
• Handle blades carefully to avoid bending or cracking; a damaged blade will cause vibration
• Verify mounting orientation and secure fasteners; check that the motor shaft and hub seat properly

This thermistor assembly is the refrigerator/freezer temperature sensor that monitors internal air temperature so the control board can maintain proper cooling. Replaces a faulty sensor to help restore accurate temperature regulation. What it does:

• Senses cabinet temperature and sends a variable resistance signal to the control board
• Allows the control system to adjust compressor and damper operation for consistent cooling
• Commonly linked to erratic temperatures, freezer icing, or fridge not cooling properly
• Used wherever the control requires a thermistor input for temperature feedback

• One thermistor assembly

• Disconnect power before starting any repair to avoid electric shock
• Handle the sensor and wiring gently; avoid crushing or kinking the thermistor lead
• Route and secure the harness as removed to prevent interference with moving parts
