No. 10 grounding

Includes service line.

This defrost heater melts frost and ice on the evaporator so your refrigerator can maintain proper airflow and cooling. It's the heating element used during the appliance's automatic defrost cycle. What it does

• Warms the evaporator coil to remove frost and ice buildup
• Restores normal airflow through the evaporator for consistent cooling
• Helps stop frost-related symptoms like reduced cooling or ice-covered coils
• Works as part of the defrost system along with the thermostat and control timer/board

• One defrost heater

• Disconnect power to the appliance before servicing to avoid shock
• Handle the heater carefully; avoid bending or damaging the element
• Inspect and, if necessary, test the defrost thermostat/bi-metal and wiring when replacing the heater

This aluminum strap secures the defrost heater firmly against the evaporator coil to maintain proper contact during defrost. Correct contact improves heat transfer so frost melts evenly and helps prevent recurring ice buildup on the evaporator.

• Secures the defrost heater to the evaporator for proper contact and heat transfer
• Promotes complete, even defrosting across the evaporator coil
• Helps reduce repeat frost/ice accumulation caused by a shifted or loose heater
• Typical clues include a loose heater, uneven frost pattern, or rattling near the evaporator

• Disconnect power and allow ice to melt before accessing the evaporator
• Use care around sharp fins and fragile refrigerant tubing; do not puncture or deform the coil
• Position the heater per your model's parts diagram and tighten the strap for firm, even contact
• Verify wiring is routed clear of the fan and moving parts before reassembly

The Defrost Thermostat is an OEM part for Frigidaire refrigerators. It monitors the temperature of the evaporator coils and activates the defrost heater when necessary. This process prevents frost buildup on the coils, ensuring the refrigerator maintains optimal cooling efficiency.

You should replace the defrost thermostat if it becomes faulty or damaged. Common causes of a bad defrost thermostat include electrical failures, regular wear and tear, or temperature fluctuations that can degrade the component over time.

Symptoms of a bad defrost thermostat include:

• Excessive frost buildup on the evaporator coils
• Refrigerator not cooling properly
• The defrost cycle not activating
• Increased energy consumption

This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore models.

Hex washer head ,10-32 x 0.375. Ground

This rubber compressor mounting grommet cushions and isolates the compressor to reduce vibration and noise that can transfer to the cabinet. It helps maintain stable compressor positioning for quieter, smoother operation. What it does:

• Absorbs compressor vibration to lower noise and rattling
• Dampens movement that can cause abrasion or wear on mounting hardware
• Helps maintain proper alignment of the compressor assembly
• Common symptom: excessive buzzing, vibration, or rattling from the back of the appliance

• Always disconnect power to the appliance before servicing.
• Support the compressor before removing mounts to prevent shifting or damage.
• Inspect surrounding mounts and hardware; replace any worn or damaged pieces.

This compressor kit is made to be used with freezers and refrigerators by several manufacturers. It includes the compressor as well as all small parts associated with it. The compressor is a component that helps move the refrigerant throughout the appliance's system. Temperature sensors indicate when the compressor should run. If the compressor is damaged, it may make strange noises, no longer cool properly, or could begin to overheat.If any of these issues are present, the compressor should be replaced. First, make sure the refrigerator is not connected to a power source. Remove perishable items from the appliance and place them in an icebox, cooler with ice, or another refrigerator. Locate the compressor on the back of the appliance by removing the metal guard. Remove the wire between the compressor and the capacitor before taking off the compressor. Replace this part with the new one by connecting it to the wire and reassembling the appliance.This is a compressor kit for use with refrigerators and freezers made by Crosley, Electrolux, Westinghouse, Frigidaire, Kelvinator, Tappan, and Gibson. It is sourced directly from the manufacturer and sold as a single part. This is a genuine OEM replacement part.

Galvanized Steel

This is a factory-style replacement screw used to secure appliance components. It restores proper fastening where the original screw is missing, stripped, or damaged so panels and assemblies stay firmly attached. What it does:

• Fastens panels, brackets, or components to the appliance frame or assemblies
• Replaces missing or damaged mounting hardware that can cause rattles or loose parts
• Provides the correct fit and thread engagement for a secure connection
• Helps maintain appliance alignment and safe operation

• Use the matching screwdriver or bit to avoid stripping the head
• Tighten until snug; do not over-torque to prevent thread or part damage
• Turn off power and remove any access panels before working on electrical components

The Compressor Run Capacitor is an OEM replacement part for Frigidaire refrigerators. This electrical component is essential for providing the necessary torque to start and maintain the operation of the compressor motor, which is responsible for cooling the refrigerator.

Symptoms of a failing compressor run capacitor include:

• The refrigerator not running or cooling properly
• The compressor failing to start or running intermittently
• Humming or buzzing noises coming from the compressor area

Causes of needing to replace the compressor run capacitor can include normal wear over time, exposure to high temperatures or electrical surges, or physical damage to the capacitor itself.

This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore refrigerator models.
