Genuine Balboa Temp/Hi-Limit Dual Sensor — 32016
The genuine Balboa Water Group dual-purpose temperature + hi-limit sensor for Balboa M7 systems with a dual-sensor heater — one sensor assembly handles both readings. 24″ cable, 1/4″ bulbs, 2-pin plug. Balboa part number 32016; also the correct replacement where Balboa 30382 was fitted.
If your BP-series spa pack is throwing temperature or sensor errors (like Sn codes) and the board checks out, this sensor is the usual fix — and it’s a simple unplug-and-swap.
Looking to save a few dollars? We also carry the HydroQuip-built equivalent of this sensor — same fit and function, aftermarket label.
