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.
worked like it was supposed to.
Good service fast shipping good price
I used the AMP connector adapter to connect a new heater from SpaDepot. We had just refilled the tub, added chemicals and the old heater died. After ordering the new heater I had a few questions and the customer service was excellent with quick answers. To avoid draining and refilling the tub I clamped the hoses using a c-clamp and hardwood slats. It worked fine with very little water loss. The new heater works great and I'm a happy customer.
the customer service was helpful
Good description of part online. Fast service and the part installed easily in a Hot Spring/Watkins Heater (6 kW) and IQ2020 Control Board. Works as advertised!!
Changed it out and now have a working hot tub again!
