Parts for Kenmore 253.77120611 (25377120611, 253 77120611): 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

This scroll is the compressor's internal spiral element that helps circulate refrigerant so your refrigerator can cool. Replacing a damaged scroll restores proper compression and helps the cooling system run more reliably. What it does:

• Compresses refrigerant by mating spiral elements to raise pressure for the refrigeration cycle
• Restores proper system compression when a worn or damaged scroll causes poor cooling
• Can reduce abnormal compressor noise caused by internal wear or damage
• Works as a direct replacement component when the compressor is serviced or rebuilt

• Requires qualified HVAC/refrigeration service; compressor work involves refrigerant handling and brazing
• System must be evacuated and charged per manufacturer specifications after installation
• Inspect and replace associated gaskets, seals, or oils per OEM guidance during service
• Disconnect power and follow proper lockout/tagout before starting work

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

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
