Parts for Kenmore 253.77110512 (25377110512, 253 77110512): Unit Parts

This electronic control is the user interface and control board that manages oven functions, timers and temperature regulation to restore responsive controls and proper cooking cycles. Fits as the direct replacement control assembly. What it does:

• Replaces a faulty oven control board to restore display, keypad and timed functions.
• Manages temperature setpoints, bake/broil cycles and timed cooking operations.
• Commonly used when the display is blank, buttons are unresponsive, or oven fails to heat properly.
• Interfaces with sensors, switches and relays to coordinate heating elements and fans.

• Disconnect power to the appliance before servicing to avoid shock risk.
• Handle the board by its edges; avoid touching components and connectors to prevent ESD damage.
• Verify connector orientation and secure all fasteners; ensure wiring harnesses are fully seated.

This thermistor is the refrigerator temperature sensor that helps the control board monitor and regulate cooling. Replacing a failed thermistor restores accurate temperature readings for more consistent fridge and freezer performance. What it does:

• Senses internal air temperature and sends that information to the control board
• Helps the defrost and compressor cycles run at the correct times
• Commonly linked to symptoms like inconsistent temperatures, error codes, or a unit that runs constantly
• Does not control cooling directly but provides the temperature feedback the system needs

• Always disconnect power to the appliance before beginning service
• Typically located in the fresh food or freezer compartment near the evaporator
• Handle the sensor and wiring gently; avoid pulling on the wires or bending the probe sharply
• If troubleshooting, verify wiring and sensor resistance per the manufacturer's service instructions before replacement

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

A replacement start/run capacitor that helps the refrigerator's motor(s) get up to speed for reliable cooling and circulation. Restores proper motor starting when the original capacitor has failed. What it does:

• Provides the electrical boost needed for compressor and fan motors to start and run smoothly
• Commonly replaced when motors hum, fail to start, or fridge cooling is inconsistent
• Helps prevent motor overloads and repeated hard-start cycling when functioning correctly
• Matches the original part's role in the appliance's electrical starting circuit

• Disconnect power to the appliance at the breaker before servicing
• Discharge the capacitor before touching terminals to avoid shock; use insulated tools
• Verify terminal orientation and secure wire connections; do not force fit

This dryer drive motor turns the drum and blower assembly so laundry tumbles and dries evenly. A reliable replacement that restores drum rotation and normal dryer operation. What it does

• Spins the drum and powers the blower to move air through the dryer
• Can cause burning smell or smoke if motor bearings seize
• Restores mechanical rotation when worn or failed

• Disconnect power before starting any repair
• Installation typically requires removing the dryer cabinet or access panels and unplugging electrical connectors
• Verify mounting hardware and blower wheel alignment during installation; retain or replace fasteners as needed
• If you smell burning or see smoke, stop use and replace the motor; check surrounding components for damage

Replacement evaporator fan blade that moves cold air across the evaporator coil and through the refrigerator compartments to help maintain even temperatures. Restores airflow to reduce warm spots and improve overall cooling consistency. What it does:

• Spins on the evaporator fan motor to circulate cold air through the freezer and fresh-food sections.
• Restores proper airflow when the original blade is cracked, warped, or broken.
• Common symptoms prompting replacement: reduced or uneven cooling, rattling/scraping noises from the freezer, or visible blade damage.
• Helps prevent excessive frost buildup by maintaining steady airflow over the evaporator.

• Disconnect power to the appliance before beginning any service.
• Handle the blade carefully; edges and broken pieces can be sharp.
• Ensure the blade is fully seated on the motor shaft and any retaining hardware is reinstalled per the OEM's guidance.

This printed wiring diagram shows the appliance's electrical schematic and component connections to help identify circuits and troubleshoot electrical issues. Handy reference for service techs and experienced DIYers. What it does:

• Displays component locations, wiring color codes and connector IDs for the appliance's control and power circuits
• Helps trace power to motors, compressors, lights, switches and electronic controls when diagnosing loss of power or intermittent operation
• Clarifies circuit paths for replacement of damaged harnesses, switches or control boards
• Useful for confirming correct wire routing during reassembly after repairs

• One printed wiring diagram sheet

• Disconnect power to the appliance before performing any diagnostics or repairs
• Use the diagram as a reference only; verify wire continuity and voltages with proper test equipment
• Handle the printed diagram carefully to avoid creasing or damage; store with the appliance service information
