Parts for Frigidaire 21844A: 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 is a compressor used in several types of home appliances. The compressor is designed to take cold gas in the appliance and place it under pressure so the gas raises in temperature. It is then moved through the refrigerator system to ensure the unit stays cold throughout the appliance. This part can become damaged or malfunction, which may cause the motor to stop running, make the motor noisier, or cause the motor to never stop running.If this happens, the compressor will need to be replaced. A basic set of tools will be needed. A pair of work gloves can also be useful. First, locate the compressor as it may be in various locations depending on the appliance model. Unplug the appliance before removing the compressor. Install the new compressor using the original bolts and nuts before turning the power back on and resuming normal use.This part is sold on an individual basis. The compressor is made to be used with refrigerators, ranges, stoves, ovens, air conditioners, and freezers created by Gibson, Frigidaire, Kelvinator, Montgomery Wards, Westinghouse, Tappan, JCPenney, Universal, and Kenmore. It is an authentic OEM replacement part directly sourced from the manufacturer.

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

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 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
