Parts for Kenmore 253.77125412 (25377125412, 253 77125412): Unit Parts

This evaporator fan blade circulates cold air inside the refrigerator compartment to help even cooling and proper frost management. A worn or damaged blade can reduce airflow, cause uneven temperatures, or create noise. What it does

• Moves air across the evaporator coil for consistent cooling and defrost performance
• Restores proper airflow if cracked, chipped, or unbalanced blades reduce fan efficiency
• Helps eliminate unusual rattling or vibration caused by damaged blades
• Works with the evaporator fan motor to maintain refrigerator temperature stability

• One fan blade

• Always disconnect power before servicing the appliance to avoid electrical shock
• Access typically requires removing interior panels or the freezer evaporator cover; follow your model's service instructions
• Align the blade on the motor shaft and seat it fully—do not force or bend the blades
• Inspect the motor shaft and mounting for wear; replace the motor if the blade won't seat securely

The Heater is an OEM part for Frigidaire air conditioners. Designed to provide supplemental heating, this heater extends the usability of your air conditioning unit into the colder months, enabling both cooling and heating from a single appliance. 

Causes of a bad heater can include electrical faults like short circuits or failing elements, accumulation of dust or debris that impedes functionality, and general wear and tear that deteriorates its components over time.

Symptoms of a bad heater include:

• Reduced heating efficiency, failing to adequately warm the space
• Circuit breaker trips when the heater is turned on
• Unusual or loud noises during operation
• Smell of burning when the heater is active

This OEM Frigidaire part is also compatible with Electrolux, Gibson, Kelvinator and some Kenmore models.

This defrost drain pan collects and channels water from the refrigerator's defrost cycle to prevent leaks and pooling under the cabinet. It restores proper drain flow and helps keep the area beneath the unit dry. What it does:

• Catches and routes melted frost and defrost water to the drain system or evaporator area
• Prevents water from pooling under the refrigerator that can cause odors or floor damage
• Works with the evaporator and defrost components to maintain normal condensation management
• Commonly replaced when cracked, warped, or leaking during defrost cycles

• One defrost drain pan / evaporator tray

• Turn off power to the appliance before servicing to avoid electrical shock
• Access typically requires removing lower kick plate or internal shelves; follow your model's service instructions
• Inspect surrounding seals, drain tube, and mounting tabs; replace any damaged components to ensure a proper seal

The Thermistor is an OEM replacement part for Frigidaire room air conditioners. Located within the air conditioner unit, the thermistor accurately monitors and regulates the equipment's internal air temperature. Precisely calibrated at the factory, the thermistor allows the unit to continuously achieve and maintain the preset cooling level preferred by the user. 

Symptoms of a bad thermistor include:  

• Inconsistent or fluctuating room temperatures
• Difficulty reaching or maintaining desired temperatures  
• The control panel shows abnormal temperature readings

Causes can be age-related deterioration of sensing components, moisture exposure damaging circuitry, or loose wiring connections preventing exact temperature measurement over time. This OEM thermistor restores precise temperature control.

Replacing a faulty thermistor prevents improper compressor cycling which wastes energy. Compatible with Electrolux, Gibson, Kelvinator, and Kenmore models.

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 power cord restores electrical supply to your appliance so it can run safely and reliably. Designed to match the original cord's fit and function for straightforward replacement. What it does:

• Provides the main AC connection to restore power when the cord is damaged or fails
• Replaces cords with cracked insulation, exposed wiring, or loose connections
• Helps stop intermittent power, arcing, or loss of power caused by a faulty cord
• Matches original wiring configuration for proper fit and connection

• Turn off power at the breaker and unplug the appliance before servicing.
• Use proper tools and secure all wire terminals; avoid pinching or crushing the cord.

This capacitor supplies the temporary electrical boost motor compressors need to start and run smoothly. Replacing a failed capacitor can restore reliable startup and help the refrigerator maintain proper cooling performance. What it does:

• Provides a momentary voltage boost to the compressor motor during startup
• Helps the compressor run more efficiently and prevents hard-starting
• Commonly linked to symptoms like a humming compressor, repeated clicking, or no-start condition
• Prevents excessive stress on start relays and other starting components when functioning properly

• Disconnect power to the appliance before starting any work
• Capacitors can hold charge—discharge safely with insulated tools
• Handle terminals carefully and match polarity/terminals to the original part

This replacement rail is a single pull-out drawer slide that restores smooth movement and proper alignment for refrigerator drawers and bins. It helps stop sticking, slipping, or uneven drawer travel so trays open and close reliably. What it does

• Replaces a worn or damaged drawer slide to restore smooth, even drawer movement.
• Supports proper alignment and prevents drawers from binding or falling off their tracks.
• Commonly used when drawers feel loose, catch, or do not fully extend or retract.
• Fits as a single rail—use with the matching opposite side if replacing both rails.

• One rail (drawer slide), sold individually.

• High-level: remove the drawer or bin to access the rail; compare orientation before removing old part.
• Use basic hand tools; keep screws and fasteners for reassembly if the new rail does not include them.
• For safety, unplug or disconnect power to the appliance if working near electrical components.

This base is the lower cabinet support that mounts under the refrigerator to protect internal components and provide a finished appearance. It restores proper support and keeps wiring and components enclosed for safer operation. What it does:

• Forms the refrigerator's lower cabinet support and helps secure internal components.
• Protects compressor lines, wiring, and other serviceable parts from debris.
• Restores proper fit and finish where a cracked or missing base causes gaps or exposure.
• Helps reduce drafts under the cabinet that can allow dust and pests inside.

• Disconnect power to the appliance and move the unit away from the wall before starting.
• Support the cabinet while removing or installing the base to avoid stressing brackets or wiring.
• Keep fasteners and clips organized; replace any damaged mounting hardware.
