HydroQuip Sensor Assembly Set Replacement for Balboa 30337

Exact fit

The replacement part was an exact fit and the installation was simple

Temp sensor assembly

It worked fine and SpaDepot gave me the correct part number to order.

Never buy electronics from Amazon

I had purchased a sensor assembly from Amazon, It stated it was a Balboa. After I installed it my hot tub water was still not heating up. Since my hot tub is an 05 model I almost purchased a new circuit control panel for it. I instead decided to order another sensor from Spa Depot and it arrived quickly and after installation worked perfect. This could have been a very costly mistake and a royal pain trying to track down a hot tub issue that I had assumed had been repaired.
