This high limit switch was exactly what I needed for my older hot tub. I was so happy that it worked! Thanks Spa Depot for still carrying this !
replacing these parts resolved my heating problem,
Easy to order, good price and easy to install.
Hot tub was probably 99 degrees or so but the digital display said it was maxed out at 109.... i replaced both sensors and now it appears to be fixed.... set at 104 and feels like 104.... very fast shipping. Will use again if needed in the future.
These folks are always so helpful and save me expensive repair costs.
