Hi Jeremy H,
Thanks for your response. good advice on the heat sensor. The reason that I am confused about the status of the circulation pump in my spa is that I thought it was working. Although I couldn't feel much vibration in it, I had the large pump off and took off the outflow hose and the pump seemed to be moving water....but come to think of it, maybe I was duped but the water pressure just moving water through the pump without the pump doing anything.....is that possible? If not, then I'm not sure that it is the circulation pump. Any additional thoughts?
It's 9F outside, so I haven't hustled out there this morning to check on the circulation pump....but, it is original to the unit....that I do know without looking. Probably is the culprit. Any suggestions on what brand to get?
Best,
David
