Parts for Frigidaire FFRH18L2R21: 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

This electronic control is the appliance's main control board that manages cycles, user inputs and timed functions, restoring proper electronic operation and interface response. Replaces a failed or unresponsive control module to return normal control to the appliance. What it does:

• Interprets user inputs and runs the appliance's programmed cycles and timing
• Switches power to motors, heaters and valves according to selected settings
• Monitors sensors and timing to coordinate cycle progress
• Common symptom fixes: unresponsive control panel, no cycles starting, erratic or incorrect cycle behavior, or display/control errors

• Disconnect power to the appliance before accessing or replacing the control to avoid shock.
• Handle the board by its edges and avoid touching components; take electrostatic discharge (ESD) precautions.
• Verify connector locations and orientation before unplugging; match all wiring exactly when reconnecting.

A direct-replacement power cord that restores electrical connection to compatible Frigidaire appliances. Simple swap-in part to replace a damaged or worn cord so your appliance can receive power safely. What it does:

• Provides the electrical connection between the appliance and the wall outlet.
• Replaces frayed, cut, or damaged cords that cause intermittent power or unsafe operation.
• Helps restore normal appliance operation when a failed cord is the source of a power issue.
• Designed to match the OEM fit and connections for the specified part number.

• One replacement power cord.

• Disconnect power at the breaker or unplug the appliance before beginning any work.
• Follow the manufacturer's wiring diagram when connecting.
• Use only compatible screws/connectors and route the cord as the original to avoid pinch or abrasion.

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 replacement capacitor stores and releases electrical energy to support proper operation of the appliance's circuit. Replacing a weakened or failed capacitor restores reliable startup and smooth performance in the affected component.

• Stores electrical energy and delivers a brief boost during startup as designed by the circuit
• Helps stabilize operation, reducing humming, stalling, or overheating from a weak capacitor
• Common signs include motors that hum but won't start, intermittent operation, breaker trips
• Visual clues of failure: swollen case, leaking oil, or burnt odor

• Disconnect power and verify no voltage is present before servicing
• Properly discharge the old capacitor using safe, approved procedures
• Note wire positions or take a photo; transfer leads to the matching terminals securely
• Mount securely in the existing bracket/strap; keep terminals clear of contact and test operation

A replacement dryer heater assembly that supplies the hot air needed to dry clothes. Restores normal drying performance when the original heater element fails or stops producing heat. What it does

• Heats air passing through the dryer drum so laundry dries efficiently.
• Commonly replaces a failed or open heating element causing no heat or long drying times.
• Works with the dryer's blower and thermostats to maintain operating temperature.
• Helps resolve symptoms like clothes remaining damp or extended cycle times.

• One heater assembly as shown.

• Disconnect power to the dryer before servicing to avoid shock or injury.
• Access typically requires removing the dryer rear or front panel; follow the model's service manual.
• Inspect related parts when replacing the heater.

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.
• Tighten screws until snug; avoid overtightening to prevent damage.
• Follow OEM service instructions.
