Kenmore / Sears Fuse Or Sensor

If your microwave shuts off mid-cycle or won't heat, the thermostat may have failed. This safety control monitors temperature and protects components.

This is a thermal fuse designed to protect the microwave's electrical circuit from overheating or power surges. It is a one-time-use safety device that blows to cut power when unsafe conditions are detected. Replace this fuse if the microwave is completely dead and will not power on at all.

Oven won't heat or stops heating during cleaning cycle? The high-limit safety switch cuts power when temperatures exceed safe limits. Moderate DIY fix.

Oven not heating to set temperature or heating too slowly? This thermostat controls oven temperature cycling. Test for continuity to diagnose the issue.

Microwave won't turn on or has no power? This fuse and holder assembly restores overcurrent protection when a blown fuse interrupts operation.

Thermistor is a temperature-sensing replacement that monitors refrigerator and freezer temperatures so the control board can regulate cooling. Replacing a faulty thermistor restores accurate temperature readings and helps stabilize cooling performance. What it does:

• Senses interior/evaporator temperature and sends a signal to the control board for temperature regulation.
• Helps prevent erratic cooling, long run-times, or inconsistent compartment temperatures when operating correctly.
• Faulty thermistors can contribute to excessive frost, failed defrost cycles, or compressor cycling issues.
• Use when the existing sensor fails to report correct temperatures or the part number matches.

• Always disconnect power to the appliance before servicing to avoid shock or damage.
• The sensor is typically mounted on or near the evaporator or inside a cabinet wall; access may require removing panels or covers.
• Handle the sensor and wiring harness gently; avoid pulling on wires or bending the sensor element.

This is a normally open cooling fan thermostat that activates the oven's cooling fan when internal temperatures reach a set threshold. It helps regulate airflow to protect surrounding cabinetry and electronic controls from excessive heat. Replace this thermostat if the cooling fan fails to turn on during or after oven use, or if the fan runs continuously without shutting off.

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 thermostat controls oven/dryer temperature by opening or closing its contacts as the appliance reaches set temperatures, helping maintain safe and consistent operation. Replaces a worn or failed thermostat to restore proper temperature regulation. What it does:

• Senses temperature and interrupts heating when limits are reached to prevent overheating
• Re-establishes heating when temperature falls, maintaining normal cycle performance
• Commonly installed when an appliance won't heat, overheats, or cycles erratically
• Works as a direct replacement for the OEM thermostat designed for compatible LG units

• One thermostat

• Disconnect power to the appliance before starting any repair to avoid shock or injury
• Note wire locations or take a photo before removing wiring; reconnect wires to the same terminals
• Use a multimeter to verify thermostat continuity and correct operation before and after replacement

This thermostat controls refrigerator temperature by opening and closing the cooling circuit as needed to maintain set temperatures. Replaces a failed or intermittent temperature control to help restore consistent cooling and food safety. What it does:

• Senses cabinet temperature and signals the cooling system to cycle on or off
• Stops continuous running when thermostat fails closed or restores cooling when stuck open
• Commonly used to address inconsistent temperatures, warm spots, or compressor short-cycling
• Passive electromechanical component—no programming required

• Disconnect power to the appliance before starting any repair
• Handle terminals and sensor capillary carefully to avoid bending or damage
• Confirm wire connections match the old thermostat and secure spade terminals firmly

Microwave won't power up or shuts off after seconds? Failed thermostats cause intermittent operation. Test for continuity—straightforward repair.

This thermal fuse is a safety device that cuts power to the dryer's heating element if the internal temperature exceeds a safe limit. It is a one-time-use component that cannot be reset once tripped. Replace this part if the dryer runs but produces no heat, or if the dryer does not start at all.

This thermostat controls refrigerator temperature to help maintain proper cooling and prevent spoilage. It replaces a failed or inaccurate temperature control to restore consistent operation. What it does:

• Senses internal temperature and signals the compressor to cycle on/off
• Helps keep food at steady, safe temperatures when functioning correctly
• Commonly replaces thermostats that cause warm temperatures or inconsistent cooling
• Works as a direct replacement when matching the OEM part number

• Always disconnect power to the appliance before servicing to avoid shock or injury
• Handle the sensor and terminals carefully; avoid bending or damaging components
• Basic hand tools are typically required; follow your model's service manual for exact instructions

Microwave won't power on or display anything? A failed thermostat is often the cause. This part regulates temperature to prevent overheating. DIY fix.
