My pentair minimax 100 isn't firing up. The control knob (mechanical) does click when it reaches the point where the heater should be kicking on. I don't see any blinking LEDs, it appears there is nothing happening beyond the mechanical thermostat knob clicking when it should be turning on. In my mind it appears the control knob has power and is working properly, but beyond that nothing is working. No LEDs blinking, nothing. I did find that the main board had a loose ground, pushed that on tightly, no difference. Any ideas?
PS -- Will take pics if that helps encourage responses
