Icemaker Thermistor Parts

Freezer not cooling or frosting over? This defrost thermostat monitors temperature and controls the defrost cycle to prevent ice buildup and restore airflow.

Frost buildup in your freezer? This defrost thermostat monitors evaporator temperature and controls the defrost heater to prevent ice accumulation.

Refrigerator not cooling properly or freezing food? A faulty temperature sensor causes inconsistent temps. Simple DIY fix restores accurate cooling.

The NTC thermistor is a temperature sensor located near the microwave's magnetron that monitors internal temperature for proper cooking control. Replace when food cooks unevenly, the microwave overheats, shuts off unexpectedly, or displays temperature-related error codes.

This 250V, 1A fuse protects your washer's control circuit from overcurrent. Replacing it can restore control power once the root cause is corrected.

• Opens to protect electronics when current exceeds its 1A rating
• Check this part if the washer has no power, the control panel is dead, or it won't start
• A blown fuse will test open for continuity
• Repeated failure points to an underlying short or component fault that must be fixed

• Disconnect power before servicing
• Access the fuse at the control board or fuse holder
• Replace only with the same rating: 1A, 250V
• Inspect wiring/components and correct any short before restoring power

Fix ice buildup in freezer or warm refrigerator temps. This defrost thermostat clips onto the evaporator. Moderate DIY repair, 1-2 hours with thawing.

This humidity sensor detects moisture levels inside the microwave cavity during cooking, allowing the control board to automatically adjust cook time and power. It is typically mounted inside the cooking compartment or vent area. Replace this sensor if your microwave's auto-cook or sensor-cook modes no longer work correctly, food is consistently overcooked or undercooked, or the unit displays a sensor error code.

These moisture sensor rods detect how damp the load is and signal the control, helping the dryer stop at the right time. Replacing worn or coated rods restores accurate Auto Dry performance and reduces damp loads or overdrying.

• Measures moisture by sensing conductivity across the rods as clothes tumble
• Sends feedback to the timer/control to adjust cycle length on Sensor/Auto Dry
• Safe symptom matches: cycles end too soon or run too long, clothes remain damp, Auto Dry doesn't advance reliably
• Residue from dryer sheets/fabric softener can insulate the rods and affect readings

• Disconnect power (and shut off gas supply for gas models) before servicing
• Access the rods at the front bulkhead/lint filter housing; panel removal may be required on some models
• Remove mounting fasteners, transfer wiring in the same orientation, and secure the new rods
• Ensure the sensing surfaces are clean and unobstructed; test on an Auto Dry cycle

AC not cooling consistently or won't turn on? This thermostat senses temperature and cycles the compressor. Simple continuity test diagnoses failures.

This is a high-limit thermostat that monitors the temperature of the heater element in a window or room air conditioner equipped with supplemental heat. It acts as a safety device by cutting power to the heater if temperatures exceed safe levels, preventing overheating and potential fire hazards. Replace this thermostat if the heater shuts off prematurely, fails to turn on, or if the unit is tripping due to overheating.

Fix a refrigerator that won't cool or has frost buildup with this defrost thermostat. Located on the evaporator coils in the freezer compartment.

Fix a refrigerator that stopped making ice, won't harvest cubes, or leaks from the mold. This ice maker kit restores automatic ice production. Moderate DIY.

This thermodisc temperature switch senses refrigerator evaporator temperature and helps control defrost and cooling cycles to prevent overcooling or prolonged defrost runs. It's a compact replacement part for temperature regulation systems. What it does:

• Opens or closes an electrical circuit based on temperature to signal defrost or compressor control
• Helps stop defrost heater when the evaporator reaches target temperature
• Can prevent extended cooling cycles when the sensed temperature indicates the system has reached desired cold
• Restores normal cycling when a failed thermostat causes continuous run or no cooling

• Disconnect power before servicing to avoid shock or injury
• Confirm location and orientation with the appliance wiring diagram before removal
• Handle the sensor element carefully; avoid bending or damaging the capillary/sensing tip
• After installation, observe normal defrost and cooling cycles

If your dryer won't heat or shuts off early, the thermal limiter may have failed. This safety device cuts power when temperatures exceed safe limits.

This is the ice level sensing arm that detects when the ice bin is full and signals the ice maker to stop producing ice. It pivots up as ice accumulates in the bin, triggering the shut-off mechanism. Replace this arm if your ice maker won't stop making ice, stops producing ice prematurely, or if the arm is broken, bent, or not moving freely.

Fix a refrigerator that won't cool or has frost buildup with this defrost thermostat. Opens the defrost cycle at the right temperature. DIY repair.
