SsllZdq Temp Monitor Control Kit 637360 for Norcold RV Refrigerators — Overheat Sensor Replacement, Plug-and-Play

The SsllZdq Temp Monitor Control Kit 637360 is a direct replacement sensor and control assembly that monitors boiler temperature and cuts power if the RV refrigerator overheats.

This plug-and-play kit is built to work with Norcold refrigerator series 2118, 1200, 1201, 1210, and 1211. It replaces the original temperature/overheat monitor so the gas-electric fridge can automatically shut down if the boiler gets dangerously hot. The unit ships as a single, ready-to-install assembly and is intended to restore the safety function found on factory systems.

How does this kit protect my RV refrigerator from overheating?

The monitor watches boiler temperature and interrupts power if readings exceed safe limits, preventing prolonged overheating. It doesn’t change cooling performance — it only protects the system by cutting power before heat can cause a fire hazard. The control is wired into the refrigerator’s existing safety circuit so it acts automatically without user intervention.

• Monitors boiler or flue temperatures continuously.
• Triggers automatic shutoff when thresholds are met.
• Integrates with the fridge’s original safety wiring.
• Prevents extended operation under unsafe thermal conditions.

Compatibility covers the common layouts and connector types used in those model families, offering a straightforward swap-in replacement. Always compare connectors and mounting points before purchase if your unit has been modified.

How simple is installation for someone with basic RV maintenance skills?

Installation is plug-and-play: unplug the old control wires and connect them to the new kit using the same terminals. No soldering or advanced electronics skills are required, but basic safety — disconnect power and propane before beginning — is essential. The kit arrives ready to mount in the same location as the original monitor.
