Description

Product Overview

The 636658 Thermistor Assembly is engineered specifically for Norcold RV refrigerators, delivering reliable temperature regulation for models 1200, 1210, and N1095. Constructed from high‑grade engineering plastic, the thermistor offers excellent wear resistance, heat tolerance, and a long service life even under the demanding conditions of mobile living. Its compact 7 × 6 × 2 inch form factor and lightweight 0.53 oz design allow seamless integration into the existing refrigeration system without requiring any modifications to the housing or wiring harness.

Each unit includes a four‑pin connector that mates directly with the refrigerator’s control board, simplifying the replacement process to a single plug‑in action. The thermistor’s precise resistance curve is calibrated to match the original OEM specifications, ensuring that the cooling cycle initiates at the correct temperature thresholds. This accuracy helps prevent both over‑cooling and under‑cooling, protecting perishable foods and extending the lifespan of the compressor.

The assembly is ideal for owners who have experienced temperature drift, frequent compressor cycling, or frost buildup in the radiator. By installing the new thermistor, users can quickly restore the refrigerator to its original efficiency, reducing energy consumption and preventing food spoilage. The part is also suitable for technicians and service centers that require a dependable, OEM‑compatible component for warranty repairs or routine maintenance.
