Parts for Frigidaire FFRE18L3S21: Unit Parts

This replacement air filter screens airborne particles before they enter the appliance. Installing a clean, intact filter helps maintain proper airflow and protect internal components so the unit can operate as designed. What it does:

• Traps dust and lint before they reach the fan and internal parts
• Helps maintain smooth, unobstructed airflow
• A clogged or torn filter can cause weak airflow or unusual noise
• Replace when the filter is missing, damaged, or will not stay seated

• 1 air filter

• Disconnect power before servicing
• Open the filter access or grille and remove the old filter
• Insert the new filter in the same orientation; ensure tabs/slots fully engage
• Do not operate the appliance without a filter installed

Electronic control board that manages a refrigerator's cooling, defrost and user-interface functions, restoring responsive controls and proper cycling when a failed system control causes erratic operation. What it does

• Regulates compressor, fans and relay switching to manage cooling cycles — failure can cause warm interior or continuous running.
• Controls defrost timing and heater operation to prevent frost buildup and excessive ice.
• Powers and communicates with the display and user controls — faults can cause blank or unresponsive controls.
• Monitors sensor inputs and coordinates system responses to maintain set temperatures.

• Disconnect power to the appliance before servicing to avoid shock or equipment damage.
• Handle the board by its edges and avoid static discharge — use anti-static precautions if available.
• Secure all connectors and mounting hardware, then power up and confirm normal operation and proper temperature cycling.

This replacement wire provides a single insulated conductor used to reconnect or repair electrical connections inside the appliance, restoring reliable signal or power flow to the affected component. What it does

• Re-establishes an electrical connection between components when an original wire is damaged or disconnected
• Helps resolve symptoms such as intermittent operation, no power to a circuit, or a loose connection in the appliance
• Prevents arcing and poor contact when a worn or frayed wire is replaced
• Used as a direct inline conductor where the OEM wiring is faulty

• One replacement insulated wire

• Disconnect power to the appliance before starting any repair to avoid shock or injury
• Match wire routing and terminal orientation to the original; secure with existing clips or ties to prevent chafing
• Ensure proper connector seating and no exposed conductor is left exposed after installation
• If multiple wires or a full harness are damaged, replace the entire harness per manufacturer guidance

Handheld remote control that restores convenient, wireless operation of your Frigidaire appliance. Use it to send commands for functions, settings and timers when the original remote is lost or no longer responding. What it does:

• Sends infrared/remote commands to the appliance so you can change settings from a distance.
• Lets you start, stop or adjust modes and timers without using the appliance control panel.
• Replaces a lost, cracked or unresponsive original remote to restore remote operation.
• Requires pairing/programming with the appliance per the owner's manual.

• Remove power or unplug the appliance before accessing internal components; handle electronics carefully.
• Use fresh batteries and insert them following polarity markings; follow local rules for battery disposal.

This temperature sensor (thermistor) monitors fresh food/freezer temperatures and sends readings to the refrigerator control board so the appliance maintains consistent cooling. Replaces a failed or intermittent sensor to restore accurate temperature control. What it does:

• Senses interior temperature and reports it to the control board
• Helps the compressor, fans and defrost system run at the correct times
• Common symptom: fridge or freezer temperatures are too warm or fluctuate
• Common symptom: unit runs constantly or cycles erratically
• Common symptom: inconsistent cooling between compartments

• One temperature sensor (thermistor)

• Disconnect power to the appliance before attempting any repairs
• Handle the sensor and wiring gently; avoid kinking or stretching the lead
• Verify connector pins align and seat fully; some models use a simple plug-in connector

This oven temperature sensor detects the internal temperature and sends readings to the range control so the oven can maintain accurate cooking temperatures. Replaces a failed or intermittent sensor to restore reliable temperature control. What it does:

• Senses oven cavity temperature and provides temperature data to the control board
• Helps the control maintain set bake/roast temperatures
• Common symptom: oven temperature is incorrect or fluctuates during cooking
• Common symptom: cook cycles take too long or oven does not reach set temperature
• Common symptom: oven displays a temperature sensor or sensor fault code

• One oven temperature sensor (1 each)

• Disconnect electrical power to the appliance before removing or installing the sensor
• Handle the sensor carefully to avoid damaging the probe or wiring and ensure proper connector seating
• Inspect wiring and connector for damage; replace if frayed or corroded

This start/run capacitor helps the compressor motor begin and run more reliably, restoring proper cooling performance when the original capacitor has failed. It provides a direct replacement that fits into the compressor electrical assembly. What it does:

• Stores and releases electrical energy to help the compressor motor start and maintain running speed
• Common symptom: refrigerator not cooling and the compressor or fan hums but won't start
• Helps reduce repeated hard-starting that can stress the compressor and relays
• Works with the compressor's start circuitry to stabilize motor operation

• Disconnect all power before accessing electrical components to avoid shock
• Verify the capacitor's terminal configuration and ratings match the original unit before installing
• Discharge the capacitor safely before removal; use insulated tools and follow safety procedures

This product is a Frigidaire air conditioner fan motor. The air conditioner fan motor is one of the most vital components in the cooling and air circulation processes of the appliance. If an air conditioner's compressor is engaging but the appliance is not circulating air, the problem could lie with the fan motor. The fan circulates air through the room when the appliance is turned on. This part also powers the fan to circulate air onto the condenser coils. The fan is responsible for cooling the room and helping the appliance to not overheat. Whenever making any repairs or installing components, be sure to unplug the appliance from its power source.This part is a genuine OEM replacement product sourced directly from Frigidaire. This is only available individually and does not include any other parts. This product is compatible with Frigidaire appliances.

This replacement blade fan moves cold air across the evaporator to help maintain even temperatures inside the compartment. It restores proper airflow for more consistent cooling and helps reduce frost buildup when working with a good motor. What it does:

• Circulates air across the evaporator to distribute cold air through the compartment
• Restores airflow when a cracked, warped, or missing blade reduces cooling efficiency
• Helps reduce uneven temperatures and localized warm spots caused by poor airflow
• Can reduce abnormal noises caused by damaged or unbalanced blades

• One replacement blade fan

• Disconnect power to the appliance before starting any repair
• Remove the evaporator cover/panel to access the fan assembly per your model's service instructions
• Handle the replacement blade carefully to avoid bending the blades or contaminating the evaporator
• If the fan motor or mounting hardware is damaged, replace those parts as well for reliable operation

This screw kit is a replacement hardware pack used to restore secure fastening of appliance panels and components. It provides the standard mounting screws needed when original fasteners are missing, damaged, or worn. What it does:

• Replaces missing or stripped screws that hold panels, trim, or small assemblies in place
• Restores secure fit to reduce rattling, vibration, or loose parts
• Helps correct minor alignment issues caused by lost fasteners
• Useful when preparing for panel removal/reinstallation during service

• Disconnect power to the appliance before servicing.
• Use the correct screwdriver or driver bit to avoid stripping screw heads.
