We have a 20 year old Aqua Spa Pak 240A-20-B Ser 36606 2hp 5.5kw 100gpm.
The switch that drives the heater will often click multi times before the heater lite will stay on and we often find the water temp is not consistent. We are in the middle of a lake on an island 250 mi from Wpg. What can I do to solve the problem.
