Genuine Balboa Stick-On Temp/Hi-Limit Dual Sensor — 30674
The genuine Balboa Water Group M7 peel-and-stick external sensor — one assembly handles both the temperature and hi-limit readings. 12″ cable, black connector, adhesive stick-on mount that attaches to the outside of the heater tube — no wet-well, no draining the spa to replace it. Balboa part number 30674.
If your Balboa M7 system uses the external stick-on style sensor and is throwing temperature or sensor errors, this is the usual fix — peel, stick, plug in.
Need the in-heater style instead? See the Balboa 32016 dual sensor (24″, 1/4″ bulbs).

Balboa M7 systems that use the external peel-and-stick dual sensor mounted on the heater tube. If your sensor instead sits in a well inside the heater with a 1/4″ bulb, you need the 32016-style sensor — send us a photo and we’ll match it.
Look at your heater tube: the stick-on style (this part) is taped/adhered to the OUTSIDE of the stainless tube with a flat pad. The in-heater style disappears INTO the heater through a fitting. Match what you have — they are not interchangeable.
