Kenmore / Sears Defrost Thermostat, Sensor

This defrost thermostat monitors evaporator temperature and controls power to the defrost heater, helping prevent frost buildup and overheating. Replacing a failed thermostat restores proper automatic defrosting and more consistent refrigerator temperatures. What it does:

• Monitors evaporator-coil temperature to control the defrost heater circuit
• Terminates the defrost cycle when the coil warms to a safe temperature
• Failure can cause heavy frost behind the freezer panel and poor cooling
• May lead to longer-than-normal run times or a heater that won't energize

• 1 defrost thermostat

• Disconnect power before servicing; access is typically behind the freezer's rear panel
• Note wiring; transfer any existing mounting clip and clamp firmly to the same evaporator tube location
• Avoid damaging fins or refrigerant tubing; route wires clear of the fan and heater
• Thermostat must be cold to read closed continuity during testing

This thermostat is a temperature-sensing switch that opens or closes an electrical circuit at a specific temperature. Replacing a failed thermostat restores accurate temperature control or over-temperature protection so the appliance operates safely and reliably. What it does:

• Senses temperature and switches its contacts to control or limit a heating or cooling circuit
• Helps maintain proper operating temperature or interrupt power if a threshold is reached
• Common symptoms of a failed thermostat: inconsistent temperatures, no heat/cool, short cycling, continuous running, or no operation due to an open circuit
• Can be checked with a multimeter for continuity change as temperature changes

• 1 thermostat

• Disconnect power before servicing; allow hot components to cool
• Note/photograph wire positions and transfer leads to the same terminals
• Reinstall with original clip/bracket/insulation in the same position for correct sensing; do not overtighten
• After reassembly, restore power and verify proper operation

This temperature sensor is the thermistor that monitors compartment temperature and reports it to the control. Replacing a failed sensor helps restore accurate cooling and steady, reliable temperatures in your refrigerator.

• Detects refrigerator or freezer air temperature and sends a resistance signal to the control board
• Helps the control regulate compressor, evaporator fan, and air damper operation
• Also called a thermistor; critical for maintaining stable, set-point temperatures
• Failure symptoms can include sections that are too warm or too cold, erratic temperature swings, or frequent cycling

• Unplug the refrigerator before servicing
• Access location varies by model (often behind an interior cover or air duct); note routing and placement before removal
• Reinstall in the original position and route wiring in the factory path; ensure the connector is fully seated
• Restore power and allow up to 24 hours for temperatures to stabilize

This defrost thermostat monitors evaporator temperature and controls power to the defrost heater, shutting it off at the correct point in the cycle. Replacing a failed thermostat helps clear frost and restore stable cooling and airflow.

• Senses evaporator coil temperature in the freezer
• Closes when cold to allow the defrost heater to run; opens as the coil warms to terminate defrost
• Helps prevent excessive frost buildup and maintains proper airflow
• Typical failure signs: heavy frost on the evaporator/back wall, weak airflow, warm fresh-food section, unit runs constantly or never defrosts

• Disconnect power and wear appropriate safety gloves before servicing
• Access the evaporator behind the rear freezer panel; note wire routing and original mounting on the refrigerant tubing
• Install the new thermostat in the same location with firm thermal contact; do not damage coil fins or tubing
• If your model uses spliced leads, use approved connectors and secure all joints; replace all covers before restoring power

Ref Defrost Thermostat L70 Comes With Bracket

This defrost thermostat monitors the evaporator coil temperature and controls power to the defrost heater. Replacing a failed thermostat restores proper defrosting, reduces frost buildup, and helps keep fresh food and freezer compartments cooling as designed.

• Senses evaporator temperature to open/close the defrost heater circuit at the correct point in the cycle
• Protects against overheating during defrost by interrupting power when the set temperature is reached
• Helps prevent heavy frost/ice accumulation on the evaporator and loss of airflow
• Common signs it may be bad: ice behind the freezer rear panel, warm refrigerator section, unit never defrosts or refreezes soon after a manual defrost

• Disconnect power before servicing; wear cut-resistant gloves
• Remove the freezer's rear panel to access the evaporator; the thermostat is typically clamped to an evaporator tube
• Match wire positions and mount the new thermostat in the same location with firm contact to the tubing
• Route wires away from the fan and sharp edges; reassemble and verify normal defrost operation

Replacement thermostat kit restores accurate temperature sensing so the appliance can maintain correct operating temperatures. Use this kit when a failing thermostat causes inconsistent temps or frequent cycling. What it does:

• Senses internal temperature and signals the control to turn heating or cooling on and off.
• Helps the appliance maintain stable temperatures and proper cycle behavior.
• Commonly replaced for inconsistent temperatures, failure to reach set temperature, or excessive cycling.
• Matches OEM function for direct replacement of the original thermostat kit.

• Disconnect power (unplug or shut off circuit) before starting any repair.
• Follow the appliance's service manual for correct routing and secure mounting of the sensor or capillary.
• Handle the sensor/capillary gently to avoid kinks or damage.

This thermostat regulates appliance temperature to help maintain proper heating and cycling for safe, consistent operation. It replaces a failed thermostat to restore correct temperature control and reduce unexpected shutoffs or inconsistent heat. What it does:

• Senses and opens/closes the circuit to control heating elements or compressors
• Can stop heating when the set temperature is reached to prevent overheating
• Commonly used when the appliance won't reach or maintain the correct temperature
• Helps address intermittent heating, continuous running, or overheating symptoms

• Disconnect power before servicing to avoid shock or injury
• Handle thermostat terminals carefully; ensure secure, correct wiring connections

This temperature sensor (thermistor) detects internal appliance temperature and sends readings to the control board so the unit maintains proper cooling. Replacing a failing sensor restores accurate temperature monitoring and helps prevent spoilage. What it does:

• Measures internal temperature and provides a resistance-based signal to the control board
• Helps the control system regulate compressor and defrost cycles
• Commonly causes warm or fluctuating temperatures, prolonged cooling, or temperature-related error codes when failing
• Works as a direct-sensing temperature input — not a user control or switch

• One temperature sensor/thermistor (single part as shown)

• Unplug the appliance or switch off power at the breaker before servicing
• Handle the sensor and its thin leads carefully to avoid damage during removal and installation
• Route and secure wiring so it does not contact moving parts or sharp edges

This bimetal defrost thermostat controls the defrost cycle by sensing evaporator temperature to protect the fridge from overcooling during defrost. Replaces a failed thermostat to restore proper defrost operation and temperature control. What it does:

• Opens and closes the defrost circuit based on evaporator temperature to allow timed heater operation
• Prevents the defrost heater from running when the evaporator is already warm
• Commonly used when the freezer is frosting up or the compressor runs excessively during defrost
• Helps maintain consistent cooling by ensuring proper defrost cycles

• Disconnect power to the appliance before attempting any service
• Mount and wire in the original thermostat location; follow OEM wiring and routing for the capillary/sensor
