Exact fit, easy to replace and got my hot tub working like new! These folks are the best at answering questions and helping to find the problem the first time!
Old one was popping my circuit randomly. I reused the temp probe and put the new one in place. Very easy. Had some trouble getting the circuit board to hold the new wires so I soldered them into the little silver discs below the slot. My old one leaked a tiny bit which causes the mineral buildup which was shorting it out, but I also noticed better water circulation in the filter and mineral cartridge since there was no air leakage in the system! Win win. All good now! Well worth it.
Arrived saturday and installed sunday. Turned on and water heated up as it should. Thanks for the quick turnaround.
