Product Description
The Balboa M7 Sensor 30382 (24″) is a genuine dual‑purpose temperature and high‑limit sensor designed for Balboa M7 spa heating systems, including those used in Colossus and Viper spa configurations. This sensor plays a critical role in monitoring water temperature and providing over‑temperature protection to ensure safe and reliable spa operation.
Featuring a 24‑inch (610 mm) cable, 1/4″ diameter metal probe, and 2‑pin connector, the sensor installs directly into the heater manifold and connects securely to the control system circuit board. In M7 systems, two identical sensors are typically used—one acting as the temperature sensor and the other as the hi‑limit sensor—allowing the control system to analyze water flow and heat rise for safe operation.
This sensor is commonly used to resolve M7‑related fault codes such as SN1, SN3, or overheating faults when a sensor failure is detected. It is a direct replacement for several equivalent Balboa M7 sensor part numbers.
