Parts for Frigidaire RT19F9DU3D: 03 - Cooling System Parts

Includes service line.

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 mounting plate secures the compressor to the refrigerator chassis, helping maintain proper alignment and reduce vibration for quieter operation. Durable stamped metal designed to fit the factory mounting points. What it does:

• Secures the compressor assembly to the appliance frame to prevent movement
• Dampens and distributes compressor vibration to reduce noise
• Maintains compressor alignment for reliable operation
• Helps keep mounting hardware and rubber isolators in correct position

• Disconnect power to the appliance before service to avoid electrical shock
• Basic hand tools required; support the compressor when removing or installing mounting hardware
• Follow the OEM service manual for torque specs and detailed installation steps

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.

This part has been discontinued by the manufacturer and is no longer available.

The defrost heater mounts at the evaporator to melt accumulated frost during the automatic defrost cycle. Replacing a failed heater restores airflow and temperature stability, preventing ice buildup that blocks vents and reduces cooling performance. What it does:

• Heats the evaporator coil to clear frost during the defrost cycle
• Maintains airflow across the coil for consistent cooling
• Common symptoms: heavy frost on the back wall or coils
• Weak/no airflow or fan hitting ice; warmer temperatures; long run times

• One defrost heater

• Disconnect power before servicing
• Access the evaporator and allow heavy ice to thaw—do not force ice off the fins
• Transfer any mounting clips and route wires like the original, away from sharp edges
• Handle the element carefully; reinstall the evaporator cover before restoring power
