Thermal Fuse Parts

Oven won't heat or shuts off during use? This thermal fuse cuts power when temperature exceeds safe limits. Moderate DIY repair with multimeter testing.

Dryer not heating or overheating? This high-limit thermostat cuts power when temperatures exceed safe levels. Common fix for no heat issues.

Dishwasher won't power on? This inline fuse protects your dishwasher's wiring harness from electrical overload. Restores circuit protection quickly.

If your ice maker stops cooling or the compressor won't run, the overload protector may have failed. This component shields the compressor from damage.

Primary limit switch that interrupts the heating circuit when temperatures exceed safe limits to prevent overheating. Replacing this switch restores the appliance's temperature safety control and helps return normal heating behavior. What it does:

• Monitors temperature and breaks power to the heating element when the preset limit is reached.
• Acts as a safety cutoff to help prevent overheating and related damage.
• A failed-open switch commonly causes no heat or intermittent heating.
• A failed-closed switch can allow excessive heat or repeated thermal trips.

• Disconnect power before servicing to avoid shock or injury.
• Note terminal locations and wiring before removal; reconnect each wire to its original terminal.
• Handle the part and terminals carefully to avoid damage; secure fasteners firmly but do not overtighten.

Microwave won't heat or shows sensor error? The cavity thermostat regulates temperature for proper heating. Straightforward DIY repair with multimeter testing.

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.

This internal-bias thermostat senses oven temperature and helps the control board maintain the set heat level. Replacing a failing thermostat restores more consistent temperature control and more reliable cooking results. What it does:

• Senses cavity temperature and signals the control to cycle the heating element or burner
• Regulates heating cycles so the oven reaches and holds the set temperature
• Common symptoms: oven takes too long to heat, temperature fluctuates or runs too hot, or the oven cycles on/off erratically

• Disconnect power (unplug or shut off circuit breaker) before servicing to avoid shock
• Access location varies by model—part is typically mounted near the control or inside the oven cavity housing
• Handle the sensor element and terminals carefully to avoid damage; reuse of mounting hardware depends on your model

This limit switch is a small position-sensing microswitch used in the oven door lock system. It tells the control when the latch is open or closed so the door can lock/unlock correctly and self-clean can run safely.

• Detects the oven door latch position and sends an on/off signal to the control
• Helps prevent self-clean from starting unless the latch is in the correct position
• Common symptoms: door won't lock or unlock, self-clean won't start or cancels, "lock door"/F9-style lock errors
• Restores proper latch feedback so the control knows when the door is locked

• Disconnect power at the breaker before servicing
• Access the door lock/latch assembly; note wire positions and orientation of the old switch
• Transfer wires one at a time and mount the new switch in the same orientation so the actuator engages the latch cam
• After reassembly, verify latch operation before starting a self-clean cycle

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

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.

Dryer won't heat or stops when hot? A faulty cycling thermostat disrupts temperature regulation. Testing with a multimeter confirms the issue.

Microwave suddenly lost power or won't heat? A faulty thermostat cavity can cause total failure. This housing secures the sensor for proper alignment.

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

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
