Assy-Case Sensor Parts

This is a cycling thermostat that monitors the temperature inside the dryer drum and signals the heating element to turn on and off to maintain the selected drying temperature. It is typically mounted on the blower housing or exhaust duct. Replace this part if your dryer is not heating, overheating, running too hot or too cool, or if clothes are taking too long to dry.

Replacement thermostat that senses and controls the appliance heating system to restore accurate heating and stable temperature cycles, helping the appliance reach and maintain the set temperature. What it does:

• Senses temperature and signals the heating element or valve to turn on/off to maintain set temperature.
• Commonly linked to symptoms such as failure to reach set temperature, temperature fluctuating or cycling erratically, or continuous heating.
• Works as the temperature-regulation component in the appliance's control pathway to stabilize performance.
• Matches the OEM function for temperature control; use when thermostat diagnostics indicate a failed or inaccurate sensor.

• Disconnect power to the appliance before attempting removal or installation to avoid shock or ignition hazards.
• Handle the sensing element and terminals carefully to avoid damage; ensure secure electrical connections and proper routing of any capillary or sensor lead.
• After installation, test the appliance through a full heat cycle to confirm correct operation.

Fix frost buildup and poor cooling in your refrigerator. This defrost thermostat prevents ice accumulation on the evaporator. Moderate DIY repair.

Range hood won't start or shuts off unexpectedly? A failed thermal cutoff fuse interrupts power when temperatures exceed safe limits. Simple repair.

Solid-state triac that switches AC power under command of the appliance's electronic control board. Replacing a failed triac restores proper power control to heating elements or motors and resolves intermittent or no-power symptoms. What it does:

• Acts as a solid-state switch on the control board to regulate AC power to heating elements or motors
• Enables the electronic control to modulate output for temperature or speed control
• Failure can cause no heat, intermittent heating, or loss of motor control
• Designed to match the original control circuit; check board mounting and connections before replacing

• Always disconnect all power at the breaker or unplug the appliance before servicing — risk of electric shock
• This part mounts to the control board; handle the board and connectors carefully to avoid damage
• Use anti-static precautions when handling electronic components;
• Verify the part number on the original board before installation

Freezer working but fridge not cooling? Coils frozen solid? Replace your defrost thermostat. Mounts on evaporator to control defrost heater cycle.

If your range meat probe gives inaccurate readings or doesn't work, this temperature sensor monitors internal cooking temps. Easy 15-minute DIY fix.

Dryer won't heat or overheats? This high limit thermostat cuts power when temperatures get too high. Common fix for no-heat issues. Easy install.

This 20-amp circuit breaker restores overcurrent protection to the appliance's electrical circuit, helping prevent damage from short circuits or overloads. It replaces a worn or tripped breaker so the appliance can receive proper power. What it does:

• Acts as an overcurrent safety device that trips when current exceeds safe limits
• Protects wiring and components from damage caused by overloads or short circuits
• Common symptom: appliance won't power on or stops powering intermittently
• Common symptom: breaker repeatedly trips during normal operation

• Disconnect power at the house breaker before inspecting or replacing the part
• Handle terminals carefully; ensure connectors are fully seated and tight
• Replace with the exact part number for fit and proper electrical rating

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

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 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

If your range won't reach set temperature or displays incorrect readings, the temperature sensor likely failed. This probe-style RTD sensor restores accuracy.

This time delay fuse protects the appliance from overheating by opening the circuit when temperatures exceed safe limits. It's a direct-replacement electrical safety fuse used in heating circuits to help prevent damage and fire risk. What it does:

• Opens the circuit when the detected temperature rises above safe operating limits to stop the heating element
• Helps prevent overheating-related damage to internal components and wiring
• Can cause intermittent or no heating when failed
• Commonly associated with symptoms such as no heat, reduced or inconsistent heating, or a unit that stops running during heating cycles

• Disconnect power to the appliance before accessing or replacing the fuse to avoid electrical shock
• Locate the fuse according to your appliance's service manual or diagram and replace with the exact part number
• If the fuse is blown, inspect heating element, thermostat/thermal cutouts, and venting for underlying faults before reinstalling

This oven temperature probe is the internal sensor that monitors cooking cavity temperature so the oven control can regulate heat for accurate cooking and bake results. It's a direct-replacement sensing probe for compatible Bosch ovens. What it does:

• Measures internal oven temperature and sends readings to the control board
• Allows the oven to maintain set temperatures for consistent cooking
• Common symptoms of a failing probe: inaccurate oven temps, oven not reaching set temperature, or temperature-related error codes
• Works with the oven's control system to help cycle heating elements or gas valve

• Disconnect power to the appliance before servicing to avoid shock hazard
• Handle the probe and its wiring gently; avoid sharp bends or pulling on connectors
• Verify connector orientation and secure connections to the control board per OEM diagram

This noise filter reduces electromagnetic interference generated by the microwave's electronics, preventing it from affecting other nearby appliances or electronic devices. It is typically located near the power input inside the microwave cabinet. Replace this filter if the microwave causes static on radios or TVs, trips breakers intermittently, or if the filter shows visible signs of burning or damage.
