Hot Tub Sensor Spa Parts Replacement for Balboa Spa M7 System,24" Temp/Hi Limit,1/4" Diameter,fit for Balboa Hot Tub Temp Sensor 32016 30344 30042 30382, 2 Pack

So I had a Temp A and B disagree message for my hot tub. Did some research and found these were a replacement for the sensors in my heating unit, so I gave it a shot. Install was easy, even with the hot tub full. Of course, I turned off the power and removed the cover to access the heater. Next I took some cling wrap to prevent water from contacting the circuit board. The plan was to pull the old one out and immediately insert the new one. That plan worked perfectly as the water that came out was like a drinking water fountain from school. I was actually impressed with the results as I was 0 for 4 in my last 4 projects. Just get them, immediate fix and very easy install.

These heat sensors replaced my dream maker spa original sensors . My jacuzzi wasn’t shutting off and had a code reading heat sensors out of balance . This solved the problem. Without the cost of a service call

Good fit and works good on my swim spa. No complaints.

They work unfortunately this was step 1 in diagnosing my swim spa overheating issues. Looks like I'm in for a board replacement.

Our hot tub suddenly started to intermittently heat to 105, despite its setting being on 102. We called the dealer and they said it needed the main printed circuit board. But the board received the input from this sensor, which was far cheaper than the board. It was worth trying, given the cost of the board. We installed it and have not had a problem since.

Worked perfectly to fix my "SnS" code. They fit super snug so took a little umph to get in, but you want it water tight. Cheap fix and easy to do. Thanks!

Only used one sensor and it has worked. It has only been installed for a week.

J ai installé les 2 et mon spa va très bien
