About this sensor

The Robertshaw Single Pole Hi-Limit Sensor 275-2662-00 is an essential safety component designed for spa heating systems that require precise temperature monitoring and overheat protection. This OEM-quality sensor features a 12-inch capillary tube with a 1/4-inch sensing bulb, providing reliable temperature detection to prevent dangerous overheating conditions in your spa's heating circuit.

Built to Robertshaw's exacting standards, this hi-limit sensor effectively resolves common spa issues including HH (high heat) error codes, ICE mode activation, and OH (overheat) conditions. At Bubbles Supply, we guarantee an exact fit for your spa system and back every sensor with our comprehensive 1-year warranty. Most orders ship the same day for minimal downtime. Ensure proper capillary tube routing during installation and verify electrical connections match your spa's wiring diagram before energizing the system.
