Thermistor Assembly (NTC) that senses appliance temperature and sends readings to the control board so the unit can regulate cooling or heating cycles. Replacing a faulty thermistor helps restore accurate temperature control and reliable operation. What it does

• Provides NTC temperature feedback to the control board for temperature regulation.
• Can cause incorrect temperatures, extended run cycles, or temperature-related error codes when failing.
• Restores reliable temperature sensing when replacing a damaged or open thermistor.
• Typically used where the control system monitors interior air or evaporator temperatures.

• Always disconnect power before servicing the appliance to avoid shock or damage.
• Handle the sensor and lead wires gently; do not kink or sharply bend the thermistor element.
• Ensure the connector is fully seated and the harness is routed clear of moving parts or heat sources.

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

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 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

The PCB Display Assembly is an OEM replacement part for LG room air conditioners. This circuit board assembly powers and controls the key display functions located on the air conditioner unit.  

Causes of a bad PCB assembly can include water or moisture damage, fluctuations in power supply, or defective electronic components.

Symptoms of a bad PCB assembly include:

• The display panel is unresponsive or blank  
• Buttons do not function properly to control temperature settings and modes
• Error codes or diagnostic messages appear on the screen
• Intermittent or flickering display

The Discharge Grille is an OEM part for LG air conditioners. It is strategically placed at the air discharge point of the unit, facilitating the directional flow of cooled air into the room. This grille not only helps to evenly distribute air throughout the space but also protects the internal components of the air conditioner by preventing the ingress of large particles that could cause damage or impede performance.

Symptoms of a bad Discharge Grille include:

• Restricted air flow, leading to inefficient cooling,
• Excessive noise as air passes through cracks or breaks in the grille,
• Visual deformities or detachment from the air conditioner unit, affecting overall functionality.

Causes of discharge grille damage often involve physical impacts, prolonged exposure to environmental conditions that can degrade materials, or improper handling during maintenance or cleaning.

This OEM LG part is also compatible with Sears/Kenmore.

This axial fan assembly moves air through the appliance to help cool components and maintain proper airflow. Replaces a worn or failed blower fan to restore normal ventilation and reduce overheating or poor performance. What it does:

• Circulates air across condenser, evaporator or internal components to support cooling and airflow
• Helps prevent overheating by removing hot air from the appliance cabinet
• Designed as a direct-fit replacement to restore OEM airflow performance

• Disconnect power before beginning any repair to avoid shock or injury
• Handle the fan blades and motor carefully to avoid damage to the assembly
• Verify fan rotation and airflow direction during reassembly; ensure connectors are fully seated

This is a control panel that is used on air conditioners. The control panel is the mechanism on the air conditioner that allows the user to adjust the temperature and control the fan speed. Replacing the control panel is very easy and can be completed within about 15 minutes. Make sure to disconnect the air conditioner from the power source prior to performing any care or maintenance on the unit.A new control panel may be needed if any of the buttons are not working. The control panel is manufactured out of a white plastic material, and if it is physically cracked, broken, or damaged in any way, it will need to be replaced. This is a genuine LG part and is an OEM part sourced directly from the manufacturer. It is sold individually. This particular control panel is compatible with air conditioners that are manufactured by the LG brand.

This part is the escutcheon that is used on air conditioning units. The escutcheon is also known as the control panel overlay. This part covers the control panel and contains the buttons which the user will press in order to control the air conditioning unit, such as adjusting the temperature or the speed of the fan and turning the air conditioner on or off. Make sure to unplug the air conditioner from the power source prior to attempting to replace the escutcheon.A new escutcheon will be needed if the original is physically cracked, broken, or damaged in any way. If any of the buttons are not functioning properly, then it is likely that the escutcheon needs to be replaced. The words on the escutcheon could also become worn off, and the user may wish to replace them for this reason.This is a genuine LG part and is an OEM part sourced directly from the manufacturer. It is sold individually. This specific escutcheon is compatible with air conditioners that are manufactured by LG.
