Hello, I have a Hot Springs Sovereign 110v that is not heating. I first replaced the heater relay board about 2 years ago (original fried). Worked fine for about a year until the main board went out so I replaced it and thermosistors. I powered it up and everything worked except the jets were pulsing. Did some research and realized I thought I had the jumpers correct (which I didn't) and I had fried the new main board. So I got another new main board and installed it (correctly this time) and now the "htr on" light is not on and not heating. Could the the jumper mistake have fried the heater relay board also or is there another piece (like the control head) that need replacing? Thanks for any help?
Also...one more thing I just noticed, the heater relay board has a 12v jumper and the main board has a 18v jumper...could this have fried the heater relay board? Thanks again
