My hot tub was working great a week ago, then it just quit heating. Its got power, to the top Control panel that works to adjust temp and all settings. All jets and lights work, it is cycling water like it is running fine. I got a Tiger River Spa, Model: Bengal w/ the IQ-2020 What I have troubleshooted already: - Tub has been drained and refilled through filter, to check for air bubbles/ air lock. - The Tub has proper power, and has been rebooted from the breaker box - The LED LIM light is on and solid green - The LED HTR light is not on; *but when you reboot the tub from the breaker box, the red HTR LED comes on for about 10secs, then turns off. *During that 10secs a multimeter shows power at the relay board to the heater, but loses power when the LED light goes off. - The LED Control Unplugged light is not on - The heater was replaced 3 years ago - I have pulled the relay board and the back looks good no sign of a blow out? Can anyone help me on this?
