Assy-Case Sensor Parts

This refrigerator temperature sensor detects fresh-food compartment temperature and provides the thermostat/control board with the readings needed for proper cooling management. Replacing a failed sensor restores accurate temperature feedback to the control system. What it does:

• Measures internal fresh-food compartment temperature for the control board
• Helps the fridge regulate run cycles to maintain set temperatures
• Faulty sensor can cause incorrect temperature display or inconsistent cooling

• Always unplug the appliance before attempting any repair.
• Handle the sensing tip and wiring harness gently to avoid damage.
• Use basic hand tools; follow the wiring diagram for location and routing.

This thermostat controls refrigerator cooling by sensing temperature and signaling the compressor to cycle on and off, helping maintain steady food temperatures and restore proper cooling when the original control fails. What it does:

• Senses cabinet temperature and completes/disconnects the compressor circuit to regulate cooling
• Restores cycling when a failed thermostat causes warm temperatures or inconsistent cooling
• Works with the control panel and compressor to maintain set temperatures
• Common replacement when the fridge runs constantly, not enough, or cycles erratically

• Disconnect power to the appliance before attempting any service
• Handle the sensing bulb/tube gently; avoid kinks or sharp bends
• Basic hand tools typically required; model-specific service instructions recommended

 The Thermostat is an OEM part for Whirlpool microwaves. It is a temperature-sensitive component that monitors heat levels inside the oven cavity during operation.

Causes may include damage from exposure to moisture or debris over time that disrupts accurate readings.

Symptoms of a faulty thermostat include:

• Incomplete or inconsistent heating with uneven hot/cold spots
• Food not reaching expected doneness after preset times
• Overheating errors or cycle interruptions

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

The Moisture Sensor is an OEM component specifically designed for Whirlpool washing machines. The sensor monitors moisture levels to determine when the appropriate moisture point has been reached, signaling the appliance to advance to the next step in the cycle.

Symptoms of a bad moisture sensor include: 

• Inability to advance through entire wash cycle  
• Immediate ending of cycle after short period of time
• Sensor may show moisture levels incorrectly
• LED lights indicating error codes related to moisture detection

Causes of a bad moisture sensor can be due to cracks, corrosion, or damage to its sensitive electronic components from impact or overuse. Regular cleaning and maintenance helps extend the life of the moisture sensor. 

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

This thermistor is a refrigerator temperature sensor that helps the control board monitor and regulate cooling for consistent food temperatures. It replaces a failed sensor to restore accurate temperature readings and stable cooling cycles. What it does:

• Senses internal temperature and sends a signal to the control board for proper compressor and damper control
• Helps the refrigerator maintain set temperatures and prevents overcooling or warming
• Can cause temperature fluctuations, long run times, or incorrect defrost cycles when failing
• Works with the control system to enable accurate temperature-based operations

• One thermistor temperature sensor

• Disconnect power to the appliance before beginning any repair
• Handle sensor and wiring gently; avoid pulling on wires or bending the probe sharply
• Install in the same location and orientation as the original sensor for correct readings

This thermal cut-out is a temperature-sensing safety device that helps protect the refrigerator's defrost/heater circuit by opening the circuit when temperatures exceed safe levels. It prevents overheating and helps maintain normal defrost cycles. What it does:

• Senses temperature in the defrost/heater area and opens the circuit to stop heating if temperatures get too high
• Prevents overheating of defrost heater or related components
• Can cause defrost failure symptoms when faulty, such as excessive frost buildup or poor cooling
• May also contribute to long run-times or irregular defrost cycles when not operating correctly

• Disconnect power to the appliance before servicing to avoid electrical shock
• Handle the part and wiring gently; ensure correct orientation and secure connections per service manual
• Use the exact replacement part number for compatibility

This thermistor is a temperature-sensing probe used by the refrigerator control board to monitor compartment temperature and help maintain proper cooling. Installing a correct thermistor restores accurate temperature feedback for efficient operation. What it does:

• Reads air temperature at its mounting location and sends that signal to the control board
• Helps control compressor, evaporator fan, and defrost cycles by providing accurate temperature feedback
• Common symptoms of a failing thermistor: improper or fluctuating temperatures, compressor cycling on/off, or temperature-related error codes
• Works as a direct replacement when the original thermistor fails or the wiring/connector is damaged

• Disconnect power to the appliance before starting any repair to avoid shock or injury
• Replace with the same type and mount in the original location to ensure correct temperature sensing
• Handle the sensor and wiring gently; avoid bending or stressing the probe or leads

The thermal cutoff is an OEM part for Whirlpool dryers. This thermal cutoff plays an important safety role by automatically shutting off power to the dryer's heating element in the event of excessive temperatures.

The thermal cutoff is responsible for monitoring air temperatures inside the dryer drum and air ducts. As temperatures rise past safe levels, the thermal cutoff triggers, cutting power to prevent damage and possible fire hazards.

Causes of a bad thermal cutoff can include overheating from issues such as a clogged or blocked vent hose, venting into an unvented space, an accumulation of lint, or a failing vent switch.

Symptoms of a bad thermal cutoff include:

• The dryer not heating up or heating unevenly
• Repeatedly tripping the circuit breaker during operation
• Scorching or burning odors detected from the dryer drum or vent

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.
