Parts for Lg LP121HEM: Package Unit Parts

A box-style film capacitor used in appliance control and motor circuits to stabilize voltage and filter electrical noise. Replaces a worn or damaged capacitor to help restore reliable operation and reduce electrical interference. What it does:

• Smooths and filters voltage peaks to protect controls and electronics
• Helps reduce electrical noise that can cause erratic motor or control behavior
• Supports stable operation of motors and control boards in the circuit
• Commonly replaced when capacitor is cracked, bulging, or electrically failed

• Disconnect power to the appliance before servicing to avoid shock hazard
• Discharge the capacitor before handling; capacitors can hold a charge after power is removed
• Match polarity and terminal layout to the original part; install only in the intended circuit location

This replacement cover protects internal components and restores the appliance's finished appearance. It's a direct-fit exterior panel that shields wiring and parts from dirt, moisture and accidental contact. What it does

• Covers and protects exposed internal components to reduce risk of damage or shorting
• Restores the appliance's finished look if the original panel is cracked, warped or missing
• Helps reduce dust buildup around controls and connections
• Can stop minor rattles caused by a loose or missing panel

• One replacement cover

• Disconnect power (unplug or switch off breaker) before starting any repair
• Remove access screws or clips holding the old cover, then lift or slide out the panel; reinstall the new cover in reverse order
• Use basic hand tools; avoid overtightening fasteners which can crack the cover
• If mounting tabs or clips are broken, replace them before finishing the install to ensure a secure fit

This replacement air filter helps reduce common refrigerator odors and maintain fresher-smelling interior air. It installs in the dedicated filter compartment to help keep stored food smelling neutral and reduce lingering smells. What it does

• Absorbs and neutralizes food and cooking odors inside the refrigerator
• Helps reduce stale or sour smells that can develop over time
• Supports overall freshness of stored food by filtering internal air
• Common symptom: persistent or recurring refrigerator odors despite cleaning

• One air filter designed for the refrigerator's filter compartment

• Locate the filter compartment per your owner's manual and remove the old filter before installing the new one
• Install new filter until it seats securely; follow any filter-reset steps if your model requires them
• Dispose of used filter following local regulations
• If odors persist after replacement, check for spoiled food, spills, or blocked vents

This air filter screens dust and lint at the intake to protect internal components and keep airflow steady. Replacing a clogged or damaged filter helps maintain performance and reduces strain on the system.

• Traps dust and lint before they reach the evaporator and blower
• Helps maintain proper airflow and overall cooling performance
• Reduces debris buildup on coils and helps protect the fan
• Common signs of a dirty or damaged filter: weak airflow, reduced cooling, longer run times, visible dirt or tears

• Disconnect power to the appliance before servicing
• Access the filter per your model's instructions; many units slide it out from behind the front grille
• Install the new filter in the same orientation; ensure it sits flat and fully seated
• Do not operate the unit without the filter in place

This linear transformer supplies low-voltage control power to the appliance, enabling timers, relays and control circuits to operate reliably. It restores proper control voltage when the original transformer has failed. What it does:

• Converts incoming mains to the appliance's required low-voltage control supply for timers and relays.
• Restores correct control-circuit operation when symptoms include no display, non-responsive controls, or intermittent cycle starts.
• Prevents erratic control behavior caused by a weak or failed transformer.
• Used wherever the control board requires a dedicated low-voltage feed.

• One linear control transformer.

• Disconnect power at the breaker or unplug the appliance before servicing to avoid shock.
• Verify wiring color/terminal locations and note connections before removing the old transformer.
• Handle with care; secure transformer and wiring to prevent strain or contact with hot surfaces.

This thermistor is the temperature-sensing component that lets the control monitor and regulate heat/cooling. Replacing a faulty sensor helps restore accurate temperatures, consistent cycles, and prevents temperature-related issues or errors.

• Detects temperature changes and sends a resistance signal to the control
• Helps the system start/stop heating or cooling to maintain set temperature
• Symptoms of failure: inaccurate temps, overheating/undercooling, short or extended cycles, temperature-related error codes
• Open/shorted sensor can cause the unit to stop heating/cooling or shut down

• Disconnect power before servicing; allow hot components to cool
• Access the sensor at its mounting point; note original routing and clip/bracket positions
• Transfer and reuse any mounting clips/brackets from the old sensor if needed
• Seat connectors fully and keep wires away from hot or moving parts

This NTC thermistor assembly is the temperature-sensing probe and harness the control uses to read actual temperatures and regulate operation. Replacing a failed sensor restores accurate temperature feedback for consistent performance and proper cycling. What it does:

• Senses temperature via a negative temperature coefficient element; resistance decreases as temperature rises
• Sends the signal to the control board to manage operation and cycle timing as designed
• Typical symptoms include inaccurate temperatures, not maintaining set temperature, extended run times or short cycling, and sensor-related error codes
• Often reads out of range when tested at known temperatures

• One NTC thermistor assembly

• Disconnect power to the appliance before servicing; turn off water supply if applicable
• Note original sensor placement, routing, clips, and insulation before removal
• Install the new assembly; route wiring away from sharp edges, heat, and moving parts; secure any clips/insulation as found
• Restore power and run a diagnostic or allow the unit to stabilize, then verify operation

The Blower Wheel Bearing is an OEM part for LG air conditioners. This bearing supports the blower wheel, ensuring smooth rotation and efficient airflow throughout the unit. 

Causes of a bad blower wheel bearing can include wear and tear from regular use, lack of lubrication, or damage from debris or impact. 

Symptoms of a bad blower wheel bearing include:

• Unusual grinding or squealing noises from the blower area
• Reduced airflow or diminished cooling efficiency
• The blower wheel wobbling or vibrating excessively
• The fan motor struggling to start or run smoothly

This OEM LG part is also compatible with some Kenmore models.

The Air Conditioner Fan Assembly Cross Flow is an OEM part for LG air conditioning units. This fan circulates air through the system, ensuring efficient cooling and proper airflow distribution.
