Balboa Water GroupSensor, M7, 12" Temp/Hi Limit, 1/4" Diameter, 2-pin

We had an "SN" code and the tub would not heat pas 80 degrees. Looked up a bunch of possible solutions and landed on one video that said just replace both sensors and voila! It's fixed. Did it myself - it was quick and easy. JUST SHUT OFF THE POWER FIRST :)

I was getting Sn fault. Then HH fault so I bought one new sensor.. I plugged in to one side no difference...then plugged my senor back in for that side and plugged new sensor in other side ....yes it worked so I changed it out ...now running 🏃‍♂️

Under control n work great

Fit my master spa perfect easy to install

I have been using this for about a week now.No problem with either of the two ordered. I installed this product myself. There is not much to it guys. They work our they don't. I'll give an update somewhere down the line should anything change.
