The Evaporator Fan Motor Bitron is an OEM part for GE refrigerators. This motor is responsible for circulating air over the evaporator coils and throughout the refrigerator, which helps maintain an even temperature and ensures that the refrigerator and freezer compartments stay cold. 

You should replace the evaporator fan motor if it becomes faulty or stops working. Causes of a bad evaporator fan motor can include regular wear and tear from frequent use, electrical issues, or buildup of ice or debris around the motor. These issues can cause the motor to fail or operate inefficiently.

Symptoms of a bad evaporator fan motor include:

• Refrigerator or freezer not cooling properly
• Unusual noises coming from the back of the refrigerator
• Motor not running or running inconsistently
• Frost buildup on the evaporator coils

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

The Set Screw is an OEM part for GE refrigerators. It is used to secure various components within the refrigerator, ensuring they remain firmly in place during operation. 

Over time, a set screw can become worn, stripped, or lost due to regular use or during repairs. A missing or damaged set screw can lead to loose components, which may cause operational issues or even damage other parts of the refrigerator.

Symptoms of a bad Set Screw include:

• Loose or rattling components inside the refrigerator
• Difficulty in keeping parts securely fastened
• Noise coming from the area where the screw is used
• Misalignment of parts, leading to improper functioning

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

This refrigerator crisper cover sits above the vegetable drawers, supporting the shelf surface and guiding the bins. Replace a cracked or sagging cover to restore sturdy support, smooth drawer movement, and organized storage in the fresh-food section. What it does

• Forms the shelf over the vegetable drawers and supports the glass insert
• Aligns and guides the crisper drawers for proper slide-in/slide-out
• Helps maintain correct spacing and airflow in the fresh-food compartment
• Replace when cracked, warped, or tabs are broken; if the shelf sags or drawers bind

• Includes: 1 refrigerator crisper cover

• Unplug the refrigerator and remove items from the crisper area
• If your model uses a separate glass insert, lift it out and set aside; remove the drawers
• Lift out the old cover and set the new cover flat on its supports
• Reinstall the glass and drawers; restore power and verify smooth operation

This thermostat assembly senses refrigerator temperature and signals the compressor and fans to maintain set cooling. Replacing a failed thermostat restores temperature regulation for more consistent cooling. What it does:

• Senses cabinet temperature and switches the compressor or evaporator fan on and off to regulate cooling.
• Helps maintain the user-set temperature range for food safety and efficiency.
• Commonly linked to symptoms such as the refrigerator running constantly, not cooling, or cycling frequently.
• Stop proper cooling when internal contacts wear or the sensor fails.

• Always unplug the appliance before servicing to avoid electrical shock.
• Handle the sensor/capillary carefully; avoid kinks or damage when routing.
• Match and secure all wiring connections and mounting points exactly as removed.

This DC freezer fan motor circulates cold air across the evaporator to help maintain even freezer temperatures and efficient cooling. Replacing a faulty motor restores airflow and can reduce frost build-up and temperature swings. What it does:

• Spins the evaporator/freezer fan to move cold air throughout the freezer compartment.
• Restores normal airflow when a worn motor causes weak or no air circulation.
• Helps prevent uneven cooling and excessive frost accumulation near the evaporator.
• Reduces unusual motor noises or buzzing associated with a failing fan motor.

• Disconnect power to the appliance before starting any repair.
• Access may require removing interior panels or the evaporator cover; handle evaporator fins carefully.
• Keep wiring orientation or connector positions noted to ensure correct reassembly.

This fixture heater is the heater assembly used to warm a targeted appliance component so the unit operates correctly and resists ice buildup. It restores heat where a small, localized heater is required. What it does

• Provides localized heat to a fixture or component to prevent freezing and help normal operation.
• Warms internal surfaces that can collect frost or condensation, reducing ice buildup.
• Restores heat when a failed heater causes intermittent or no warming at the fixture.
• Helps eliminate symptoms such as frost accumulation, poor component function, or temperature-related faults.

• One fixture heater assembly.

• Disconnect power to the appliance before starting any repair to avoid shock or injury.
• Handle terminals and wiring carefully; match wire connections and secure all fasteners.
• Use basic hand tools; for correct routing and placement.

This louver gasket seals the refrigerator/freezer louver to help direct airflow and keep the cabinet edge sealed from drafts and debris. It restores a proper seal to improve cooling consistency and reduce dust buildup around the louver opening. What it does:

• Replaces worn or torn louver sealing to restore a tight edge seal
• Helps maintain directed airflow through the lower louver/vent area
• Reduces drafts and keeps dust and debris from entering the cabinet gap
• Addresses visible gaps, flapping rubber, or airflow noise near the louver

• High-level replacement: typically removes and snaps into the louver channel or secures with retained clips; inspect alignment before final seating
• Use gentle, even pressure to avoid tearing the gasket; trim only if manufacturer specifies
• Disconnect power to the appliance or ensure the unit is powered down when working near electrical components
• If adhesive or fasteners are present, remove old residue and use only OEM-recommended adhesive or hardware
