Defrost Thermostat, Sensor

This temperature sensor monitors interior temperatures so the refrigerator can maintain proper cooling. It connects to the control board and provides the temperature readings the appliance needs to regulate compressor and fan operation. What it does:

• Detects air temperature in the refrigerator/freezer compartment for accurate control signals
• Helps the control board decide when to run cooling cycles
• Commonly replaced when interior temps are incorrect or fluctuate unexpectedly
• Can address symptoms like the fridge running constantly, not cooling properly, or erratic temperature behavior

• One temperature sensor (thermistor) with connector

• Disconnect power before attempting any service to avoid electrical shock
• Handle the sensor and lead gently; avoid kinking or sharply bending the probe
• Mount and route the wiring per original placement so the sensor reads ambient compartment temperature

This bi-metal defrost thermostat senses evaporator temperature and stops the defrost heater when the coil reaches the correct temperature, helping prevent overheating and ensuring proper defrost cycles. Fits refrigerators that use a bi-metal style defrost control. What it does:

• Opens/closes electrical circuit to the defrost heater based on coil temperature
• Stops the heater when the evaporator gets warm to prevent over-defrosting
• Can help resolve excessive frost build-up or failed defrost cycles when faulty
• Works as part of the defrost system to protect compressor and cooling performance

• One bi-metal defrost thermostat

• Disconnect power to the appliance before servicing to avoid shock
• Replace with the exact style and rating; handle terminals and wiring gently
• Mount at the same location and orientation as the original sensor; secure per OEM instructions

This external temperature thermistor senses refrigerator compartment temperature and helps the control board maintain stable cooling. Replaces a failed or inaccurate sensor to restore correct temperature readings and cycling. What it does

• Monitors air temperature in the fridge/freezer compartment so the control board can regulate cooling
• Can cause incorrect temperatures or excessive run time when the sensor reads inaccurately
• Useful when you see temperature fluctuations, weak cooling, or inconsistent compressor cycling
• Works as the sensor input for automatic defrost and temperature-control routines

• One external temperature thermistor (sensor)

• Disconnect power to the appliance before starting any repair
• Access may require removing interior liners, shelves, or an access panel; keep track of fasteners
• Handle the sensor lead and sensing element carefully to avoid damage

This mechanical refrigerator thermostat regulates interior temperature, letting the compressor cycle on and off to maintain your set cooling level. It's a direct replacement for worn or unresponsive temperature controls to restore consistent cooling. What it does:

• Senses cabinet temperature and signals the compressor to run or stop to maintain setpoint
• Replaces a thermostat that won't hold temperature, causes continuous running, or prevents cooling
• Works with manual temperature-control knobs (mechanical sensing and switching)
• Typical failure symptoms: refrigerator too warm, too cold, or compressor that runs constantly or not at all

• Disconnect power before attempting any service to avoid shock or damage
• Access may require removing control panels or shelves; keep track of mounting screws and orientation
• Confirm wiring and terminal placement match the old thermostat before final connection
