Thanks for all the great info Well when I tried to get my hot tub back it and going after last winter I notice the the water was no heating after 3 days the water was only 82 83ish so after looking around online and doing some checks with my multi meter I verified the resistance of the heater was in range so figured I check voltage and was only getting 110v at the heater on a 220v system so I'm assuming one of the relays on the board went or probably bad Sodier joint and with my circuit board experience be limited I came to the conclusion a new board would be what I need
