This cover tube is a molded protective housing that shields internal components and wiring from wear, heat, and debris. It helps maintain safe operation and prevents rubbing or chafing that can lead to damage. What it does:

• Covers and protects internal wiring, hoses or assemblies from contact and abrasion
• Helps direct airflow and keeps debris away from sensitive parts
• Reduces noise caused by rubbing or loose components
• Preserves component alignment and prevents premature wear

• Disconnect power to the appliance before beginning any repair.
• Installation requires partial disassembly of the appliance; keep track of screws and clips.
• Use OEM replacement and follow the service manual for correct orientation and torque of fasteners.
• If you see damaged wiring or other compromised parts, replace or repair those items before reinstalling the cover tube.

Fix a too-cold fridge or freezing food with this air damper assembly. Controls airflow between compartments to restore proper temperature balance.

Center door hinge assembly for bottom-mount refrigerators. Supports the door weight and maintains proper alignment. Replace if cracked, worn, or broken.

Protective cover for your refrigerator's PTC and compressor start device assembly. Replace if cracked, melted, or missing to shield components from damage.

Secures panels, brackets, and trim components inside your refrigerator. Replace this fastener if it's stripped, lost, or damaged to restore alignment.

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

Secures internal components to prevent rattling and shifting. Replace if bracket is damaged, broken, or parts have become loose. Verify fit with model number.

Plastic trim cap that snaps over exposed fasteners and mounting posts on your refrigerator. Replace if cracked, broken, missing, or discolored.

Protective grille cover that shields the cooling fan and directs airflow in your refrigerator. Replace if cracked, broken, or missing to restore finish.

The Shutter Knob is an OEM part for LG refrigerators. This knob is used to adjust the position of the air shutter, controlling the flow of cold air into the refrigerator compartments. Proper adjustment of the air shutter ensures optimal temperature regulation, helping to keep food fresh.

Over time, the shutter knob can wear out or become damaged due to frequent use or accidental impact. If the knob is broken or malfunctioning, it can hinder the ability to control the internal temperature, leading to uneven cooling.

Symptoms of a bad shutter knob include:

• Difficulty in adjusting the temperature settings
• Loose or broken knob
• Uneven cooling within the refrigerator compartments
• Knob not staying in the set position

Causes of a bad shutter knob can include regular wear and tear, accidental impacts, or excessive force applied during adjustments.

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

This center hinge assembly supports and pivots the middle door section to keep doors aligned and operating smoothly. Replace a worn or damaged center hinge to restore proper door movement and help maintain a tight seal. What it does:

• Provides the pivot point and structural support for the center door section to open and close smoothly
• Helps maintain door alignment to prevent rubbing, scraping, or uneven gaps
• Reduces door sag that can interfere with sealing and cooling efficiency
• Prevents binding or sticking during door operation

• One center hinge assembly

• Disconnect power to the appliance before starting any repair
• Doors are heavy—have a second person assist to support doors while removing or installing the hinge
• Remove any trim or covers to access hinge screws; align doors fully before tightening fasteners
• Use manufacturer-recommended torque; do not overtighten screws or force parts into place

This is a rear end cap that attaches to the end of the refrigerator door handle. It provides a finished appearance and secures the handle in place. Replace this cap if it is cracked, broken, or missing, which can cause the handle to feel loose or look incomplete.
