Lg Refrigerator Defrost Thermostat, Sensor

The Refrigerator Temperature Sensor is an OEM part for LG refrigerators. This sensor monitors the temperature inside the refrigerator and communicates with the control board to maintain the optimal cooling environment.

Common causes of failure include wear and tear over time, electrical issues, or exposure to moisture. A malfunctioning sensor can lead to inaccurate temperature readings, resulting in improper cooling or freezing.

Symptoms of a bad refrigerator temperature sensor include:

• Inconsistent refrigerator or freezer temperatures
• Food spoiling faster than usual
• Refrigerator running continuously or not running at all
• Error codes displayed on the control panel

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

The Defrost Sensor Assembly is an OEM part for LG refrigerators. This integral component plays a key role in monitoring the temperature within the refrigerator's freezer section, particularly during the defrost cycle. It ensures that the defrost system activates and deactivates at appropriate temperatures to maintain efficient operation and prevent frost buildup. 

Symptoms of a faulty defrost sensor assembly include:

• Excessive frost or ice accumulation in the freezer
• Refrigerator or freezer section experiencing temperature fluctuations
• Defrost cycle not running or running too frequently

Causes of defrost sensor failure often involve damage from moisture or ice, electrical faults, or degradation over time, which can lead to inaccurate temperature readings and improper defrost cycle regulation.

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

The Temperature Sensor is an OEM part for LG refrigerators. Also known as a thermistor, is responsible for sensing the temperature changes and providing the necessary feedback to the refrigerator's control board. It helps maintain accurate and consistent temperature levels, ensuring optimal food preservation and efficient cooling.

Causes of a faulty temperature sensor can include wear and tear over time, damage due to electrical issues or exposure to extreme temperatures, or sensor calibration issues. These factors can result in temperature inconsistencies, inaccurate readings, or improper cooling performance of the refrigerator.

Symptoms of a bad temperature sensor may include:

• Incorrect temperature readings on the control panel
• Temperature fluctuations inside the refrigerator
• Overcooling or inadequate cooling of food items

This OEM LG part can also be used on Kenmore/Sears appliances. 

The Defrost Sensor Assembly is an OEM part for LG refrigerators. It plays a critical role in the defrost system by monitoring the temperature of the evaporator coil to ensure that it remains at the optimal temperature to prevent frost buildup. The sensor sends signals to the control board, triggering the defrost cycle when necessary.

Over time, the defrost sensor assembly can fail due to wear and tear, electrical issues, or exposure to moisture and temperature fluctuations. When the defrost sensor malfunctions, it can cause improper defrost cycles, leading to excessive frost buildup, reduced cooling efficiency, or the refrigerator not defrosting at all.

Symptoms of a bad defrost sensor assembly include:

• Excessive frost buildup on the evaporator coils
• Refrigerator or freezer not maintaining the correct temperature
• Increased energy consumption
• Refrigerator not defrosting properly

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

The Freezer Temperature Sensor is an OEM part for LG refrigerators. This sensor monitors the temperature within the freezer compartment, sending readings to the refrigerator’s control board to maintain optimal temperature levels. It plays a crucial role in ensuring that the freezer operates efficiently and keeps food items properly frozen.

Over time, the temperature sensor can fail due to regular wear and tear, electrical issues, or exposure to extreme temperatures. A faulty sensor can lead to inaccurate temperature readings, affecting the freezer's performance.

Symptoms of a bad freezer temperature sensor include:

• Inconsistent freezer temperatures
• The freezer running continuously or not running at all
• Frost buildup in the freezer compartment
• The control board displaying error codes related to temperature

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

THERMISTOR ASSEMBLY,PTC

This replacement temperature sensor measures the compartment temperature and reports it to the control board, helping your refrigerator maintain consistent cooling. Replace a failing sensor to restore accurate temperature readings and dependable performance.

• Monitors refrigerator/freezer temperature and relays data to the control
• Helps the system regulate compressor and fan operation for steady cooling
• A failing sensor can cause temperatures that are too warm or too cold
• May lead to extended run times, short cycling, or erratic cooling

• Disconnect power before servicing; wear cut-resistant gloves.
• Location varies by model; commonly clipped to the evaporator or mounted in an air duct/liner.
• Match the connector, route wiring along the factory path, and secure the probe in its original position.
• Restore power and allow up to 24 hours for temperatures to stabilize.

This temperature sensor is the thermistor that monitors compartment temperature and reports it to the control. Replacing a failed sensor helps restore accurate cooling and steady, reliable temperatures in your refrigerator.

• Detects refrigerator or freezer air temperature and sends a resistance signal to the control board
• Helps the control regulate compressor, evaporator fan, and air damper operation
• Also called a thermistor; critical for maintaining stable, set-point temperatures
• Failure symptoms can include sections that are too warm or too cold, erratic temperature swings, or frequent cycling

• Unplug the refrigerator before servicing
• Access location varies by model (often behind an interior cover or air duct); note routing and placement before removal
• Reinstall in the original position and route wiring in the factory path; ensure the connector is fully seated
• Restore power and allow up to 24 hours for temperatures to stabilize

This temperature sensor (thermistor) detects internal appliance temperature and sends readings to the control board so the unit maintains proper cooling. Replacing a failing sensor restores accurate temperature monitoring and helps prevent spoilage. What it does:

• Measures internal temperature and provides a resistance-based signal to the control board
• Helps the control system regulate compressor and defrost cycles
• Commonly causes warm or fluctuating temperatures, prolonged cooling, or temperature-related error codes when failing
• Works as a direct-sensing temperature input — not a user control or switch

• One temperature sensor/thermistor (single part as shown)

• Unplug the appliance or switch off power at the breaker before servicing
• Handle the sensor and its thin leads carefully to avoid damage during removal and installation
• Route and secure wiring so it does not contact moving parts or sharp edges

This controller assembly is the electronic control board that manages appliance functions and user commands, restoring reliable cycle control and display operation when the original board fails. It replaces a faulty control to help return normal machine operation. What it does:

• Receives and processes user inputs from the control panel and touchpad
• Controls timing, cycle selection, and power distribution to motors, valves, and sensors
• Can stop appliance operation or cause error codes when it malfunctions
• Common symptoms: unresponsive controls, incorrect cycles, flashing/error display, or no power to controlled components

• One controller assembly

• Disconnect power before starting; verify power is off to avoid shock
• Handle the board by edges and avoid static discharge; wear an ESD strap if available
• Inspect connectors and harnesses for damage and ensure firm, correct connections
• After installation, restore power and run a test cycle to proper operation
