Kenmore Refrigerator Fuse, Thermal Fuse & Breaker Parts

Kenmore Refrigerator Thermal Fuse and Breaker Parts

Thermal fuses and overload protectors are critical safety devices in Kenmore refrigerators. When a thermal fuse blows, it cuts power to the compressor as a safeguard against dangerous overheating. Unlike a standard fuse, a thermal fuse is a one-time-use part — once it melts, it must be replaced. The overload protector (also called a start relay or thermal overload) monitors motor temperature and shuts down the compressor if things get too hot.

A blown thermal fuse or tripped overload is often a symptom of a deeper problem: a clogged condenser, a failed start relay, or a dying compressor. Before replacing these parts, confirm that the condenser coils are clean and airflow is normal. If the fuse blows again immediately after replacement, the compressor itself may be failing.

• Thermal fuse blows repeatedly: compressor may be weak or condenser clogged
• Refrigerator runs but doesn't cool: check thermal fuse continuity first
• Compressor clicks on and off: overload protector or start relay failing
• Fridge completely dead, no power: thermal fuse or breaker may be tripped
• Humming but no compressor startup: start relay or overload protector needs replacement

Kenmore Refrigerator Thermal Fuse and Overload Questions

Why did my Kenmore refrigerator thermal fuse blow?

A thermal fuse blows when the compressor or sealed system overheats — usually from a clogged condenser coil, a failed start relay, or a weak compressor trying to run too hard. Before replacing the fuse, vacuum the condenser coils at the back or bottom of the fridge. If the fuse blows again within a few days, the compressor may be failing and replacement of the entire refrigerator may be more cost-effective than a sealed-system repair.

What's the difference between a thermal fuse and an overload protector?

A thermal fuse is a one-time safety device that melts at a set temperature — once blown, it must be replaced. An overload protector (thermal overload relay) is a reusable safety switch that trips when the compressor motor gets too hot, then resets once it cools. If your Kenmore compressor clicks on and off repeatedly, the overload protector may have tripped. Let it cool for 30 minutes, then try again. If it trips again, replace the overload protector or investigate why the compressor is overheating.

How do I know which thermal fuse or breaker my Kenmore refrigerator needs?

Kenmore refrigerators are built by Whirlpool, LG, or Frigidaire depending on the model series. The model number prefix tells you the OEM builder: 110.xxxxx = Whirlpool-built; 253.xxxxx = Frigidaire-built; 795.xxxxx = LG-built. Each OEM uses different part numbers for thermal fuses and overload protectors. Enter your full Kenmore model number into the Repair Clinic parts finder to confirm the exact thermal fuse, breaker, or start relay your model needs.

Can I reset a thermal fuse instead of replacing it?

No — thermal fuses are one-time-use parts. Once the internal element melts, it cannot be reset or reused. You'll need to replace it with an OEM part. However, if you have an overload protector (thermal overload relay), that device may reset on its own once the compressor cools. Always verify which part your Kenmore model has by checking your manual or using your model number.

Kenmore Refrigerator Model Number: Where to Look

On Kenmore refrigerators, look for the model number on a label inside the fresh food compartment, along the side wall, or behind the crisper drawer. Some models place the label on the ceiling of the compartment, so check these areas before moving the appliance. Record the complete model number, including any periods, letters, or extra digits. Type it into our model number lookup and the catalog narrows to parts made for your unit. The model number filters the full Kenmore refrigerator parts selection, not just fuses or thermal protectors, so every associated part is matched to the correct refrigerator. This saves time when comparing options and helps prevent ordering a part that does not fit.
