Thermistor Parts

Dryer not heating or overheating? This thermal limit thermostat regulates temperature and prevents damage. Common DIY fix in about 15 minutes.

This temperature thermistor is the sensor that lets the control board monitor and regulate appliance temperature for reliable cooling performance. Replacing a failing thermistor can restore proper temperature control and cycling. What it does:

• Senses internal temperature and sends readings to the control board
• Helps the compressor, fans, and defrost system run at the right times
• Commonly linked to symptoms like incorrect temperatures, overcooling, or frequent on/off cycling
• A faulty thermistor can cause improper defrost timing or erratic cooling behavior

• Disconnect power before inspecting or replacing the sensor to avoid shock
• Handle the sensor and wiring connector gently to avoid damage
• Mount the sensor in the original location and secure wiring per OEM routing

This is a thermostat that monitors the temperature in the ice maker to signal when ice has fully frozen and is ready to be harvested. It acts as a thermal cutoff device to regulate the ice-making cycle. Replace this thermostat if the ice maker stops producing ice, runs continuously without cycling, or fails to eject ice at the proper time.

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 rinse aid sensor detects the presence/level of rinse aid and signals the dishwasher control so the dispenser and cycle logic respond correctly. Replaces a failed sensor to restore proper rinse-aid detection. What it does

• Acts as a reed-style sensor that notifies the control when rinse aid is present
• Helps the dispenser and control board make rinse-aid–related decisions
• Commonly replaced when rinse-aid indicators fail or rinse-aid detection errors occur
• Small, low-voltage sensing device used in the dishwasher dispenser area

• One rinse aid sensor (reed switch)

• Disconnect power to the appliance before starting any service
• Access may require removing the door inner panel or dispenser assembly; follow the service manual
• Handle gently and avoid bending the sensor leads; ensure secure electrical connections

Dryer not heating or leaving clothes damp? This thermostat with sensing cable regulates temperature and prevents overheating. Easy DIY repair part.

This sensor detects moisture levels inside the microwave cavity during cooking and communicates with the control board to adjust cook times automatically. It is a key component for auto-cook and sensor-reheat functions. Replace this sensor if the microwave fails to properly detect doneness, overcooks or undercooks food on sensor settings, or displays a sensor error code.

Washer not heating or cooling properly? This thermistor temperature sensor assembly measures internal temps and sends readings to the control board.

If your air conditioner won't start or shuts down unexpectedly, a failed compressor overload protector is often the cause. This simple swap restores starts.

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

• Measures internal refrigerator/freezer temperature and sends readings to the control board
• Helps the control board adjust compressor and fan operation for stable temperatures
• Can cause incorrect temperature display or uneven cooling when it fails
• Linked to excessive running, frequent defrost cycles, or poor cooling performance

• Disconnect power to the appliance before servicing to avoid shock or damage
• Handle the sensor and wiring harness carefully; avoid kinking or damaging the lead
• Ensure the connector is fully seated and any mounting clip or bracket is secured
• Some panel removal may be required; follow for access and reassembly

Fix a dryer that won't heat properly or overheats. This cycle thermostat regulates temperature during heating cycles. Easy DIY repair in under an hour.

This flow meter measures the volume of water passing through the refrigerator's water dispensing system. It sends signals to the control board to accurately track water usage and control dispenser operation. Replace this part if your water dispenser delivers inconsistent amounts of water, fails to shut off properly, or if the dispenser display shows inaccurate readings.

A 15 amp cartridge fuse that protects appliance electrical circuits from overcurrent, helping prevent damage to controls and components. Fits into inline fuse holders or boards where that specific fuse rating is required. What it does

• Interrupts circuit power when current exceeds 15 amps to protect wiring and electronics
• Commonly linked to symptoms like no power to controls, unresponsive display, or appliances that won't start
• Designed to be replaced when visibly blown or when continuity test fails
• Works as the exact rated safety fuse specified for compatible appliances

• One 15 amp cartridge fuse

• Disconnect all power to the appliance before accessing or replacing the fuse
• Replace with the identical fuse type and 15 amp rating only; do not substitute different ratings
• Handle carefully and mount fully seated in its holder or on the PCB as designed
• If the new fuse fails again immediately, stop — repeated failures indicate underlying electrical faults

Dishwasher not heating or shutting off mid-cycle? This thermostat regulates water temperature. Direct replacement part with moderate difficulty install.
