  1. Hi, I have a 2006 Thermospa Concord hot tub. Recently I replaced the complete spa pack after discussing with Thermospa technical support that the unit would not power up at all. After doing that I noticed the circ pump would run for 3-4 minutes then shut off, which would then cause the heater to trip on overheat because of no flow, and after 10 minutes the circ pump would come back on. So I assumed the motor on the circ pump was overheating causing the shut off (since the pump was original). I ordered a replacement pump and installed it but now the pump will not come on at all. When I measure voltage across hot to neutral on the pump leads I get nothing, but when I measure hot to ground I get 120 and when I measure neutral to ground I get 120. Also just noticed that the blower motor will not operate when turned on. Did I get a defective circuit board or is there something I'm missing here? I know the pump works because I can wire it directly to 120 bypassing the circuit board and it runs with no problem.
