Generic Temp Monitor Control Kit for Norcold RV Refrigerators — 2118/1200/1210 Series, Overheat Protection

Generic 637360 Temp Monitor Control Kit is a plug-and-play replacement assembly that monitors and protects RV Norcold refrigerator cooling units from overheating and abnormal pressure conditions.

This control kit is built to restore temperature safety and automatic protection to Norcold 2118, 1200, 1201, 1210 and 1211 series RV refrigerators. It combines a relay board, durable steel sensor, and a reliable control chip for long-term performance. The unit replaces OEM parts 634677/634678 and is designed for straightforward installation with snap-fit connectors and improved surge and moisture protection.

How does the kit prevent my RV refrigerator from overheating?

The control board continuously monitors temperature and pressure signals and will trigger protective shutdowns when values exceed safe thresholds. It uses a macro-relay for durable switching and a steel-sheathed sensor for stable readings. This reduces risk of prolonged high-heat operation and potential damage to the cooling system.

• Built-in automatic detection of low/high pressure and high temperature
• Macro-hair relay for reliable switching under load
• Steel sensor sheath for accurate, long-term temperature sensing
• Protective shutdown to avoid overheating events

Will this replace my Norcold 2118 or 1210 controller directly?

Yes — the 637360 Temp Monitor Control Kit is engineered for compatibility with a wide range of Norcold units including 2118, 1200, 1201, 1210 and 1211 series. Connectors use snap-fit locking to match the original wiring harness layout, so physical and electrical fitment is straightforward in most installations.
