Parts for Lg GR-131CN: Evaporator / Comp. Base / Drier Parts

This thermistor assembly is a temperature-sensing component that provides accurate feedback to the appliance control system so temperature and defrost cycles are regulated properly, helping maintain consistent cooling performance. What it does:

• Senses evaporator/compartment temperature and sends a signal to the control board
• Helps the control system time defrost cycles and manage compressor run cycles
• Commonly linked to symptoms such as frost build-up on the evaporator, irregular temperatures, or defrost-related fault codes
• Passive component — will not operate correctly if connector, wiring, or control board is faulty

• Disconnect power to the appliance before servicing to avoid shock or damage
• Handle the sensor tip and wiring gently; avoid bending or stressing the sensing element
• Ensure the connector is fully seated and wiring is routed the same way as the original
• For exact location and replacement steps

This PTC cover protects the refrigerator's PTC/compressor start device from dirt, moisture and accidental contact, helping the start device operate reliably. It's a simple replacement that restores the protective enclosure for the start assembly. What it does:

• Shields the PTC/compressor start relay and wiring from debris and moisture that can cause malfunctions
• Helps prevent accidental shorting or contact with terminals during operation or service
• Can resolve symptoms where the start device is exposed or the compressor area shows visible wear or damage
• Maintains correct positioning and protection of the start components for consistent compressor starting

• One PTC cover (protective enclosure) as shown

• Disconnect power to the appliance before starting any repair
• Replace only when the start device or cover is exposed and you can access compressor/start assembly safely
• Avoid bending or stressing terminals and wiring when removing or installing the cover

The Drier Assembly is an OEM part for LG refrigerators. This part removes moisture and contaminants from the refrigerant, ensuring the system operates efficiently and effectively. The drier assembly helps maintain the proper function of the compressor and other cooling components, contributing to the longevity and performance of the refrigerator.

Causes of a bad drier assembly can include clogs from debris, wear and tear over time, or contamination from moisture or refrigerant leaks.  

Symptoms of a bad drier assembly include:

• The refrigerator not cooling properly
• Frost or ice buildup on the evaporator coils
• Increased noise from the compressor
• Reduced efficiency and higher energy consumption
• You should replace the drier assembly if it becomes faulty or damaged.

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