Kenmore Refrigerator Sensor & Thermistor Parts

Kenmore Refrigerator Temperature Sensor and Thermistor Parts

A faulty temperature sensor (thermistor) in your Kenmore refrigerator causes incorrect cooling — the fridge runs constantly, doesn't cool enough, or cycles erratically. The thermistor reads the temperature inside the fridge or freezer and signals the control board when to run the compressor. When it fails, your food spoils or freezes solid. OEM Kenmore thermistor sensors are the reliable fix, and they're model-specific because Kenmore refrigerators are built by different manufacturers (Whirlpool, LG, Frigidaire, and others depending on the model series). Find the exact Kenmore thermistor for your model by entering your model number below.

• Fridge runs constantly but doesn't cool: Faulty thermistor signals "always too warm" to the control board
• Fridge too cold, food freezes: Thermistor reads low, compressor never shuts off
• Temperature erratic, cycling on/off frequently: Thermistor resistance is unstable or intermittent
• No cooling despite running compressor: Thermistor failure prevents proper cycle control
• Ice buildup in fridge section: Evaporator cycles wrong because thermistor isn't reading correctly

Kenmore Refrigerator Thermistor FAQs

Why does Kenmore have so many different thermistor models?

Kenmore is a Sears house brand built by multiple manufacturers — Whirlpool, LG, Frigidaire, and others. Your model number prefix (110, 253, 795) tells you the OEM builder, and each builder uses different thermistor sensors. That's why entering your exact model number is critical. The Repair Clinic lookup tool confirms which thermistor you need based on your specific Kenmore refrigerator.

How do I know if it's the thermistor and not the compressor?

If your fridge is running but temperatures are wrong, the thermistor is the prime suspect — it costs $15 to $40 and is far cheaper than compressor diagnosis. Listen for the compressor cycling (clicking on and off). If it's cycling constantly or never cycling, the thermistor is usually the issue. If the compressor is completely silent and the fridge is warm, then you're looking at a compressor or sealed system problem.

Can I clean a thermistor instead of replacing it?

No. Thermistors are sealed sensors — cleaning won't restore them. Once the resistance drifts or the sensor fails, you'll need to replace it. OEM Kenmore thermistor sensors are inexpensive replacements and come with exact model-specific calibration.

What's the difference between a fridge thermistor and a freezer thermistor?

Most Kenmore refrigerators have separate thermistors for the fridge and freezer sections. The fridge thermistor typically mounts in the air duct or evaporator compartment. If only one section is cold, check which thermistor is failing — your model number lookup will show you both and their locations.

Kenmore Refrigerator Model Number: Where to Look

Kenmore typically places the refrigerator model number on a label inside the fresh food compartment, often along the side wall or behind the crisper drawer. Check the ceiling of the compartment as well, especially if the first locations are empty. The model number identifies your entire refrigerator, not just its sensors or another individual part. Enter that number in the Repair Clinic search bar to narrow the full catalog to parts that fit your specific Kenmore model. Include every letter, number, and punctuation mark exactly as shown on the label. This gives you a fast, accurate match and helps prevent ordering a part made for a different refrigerator.
