Hot Spring Ace Posted December 13, 2011 Report Share Posted December 13, 2011 I am working currently on a hot spring vanguard.

With the power turned off at the breaker, inspect the small circuit board in the control box to see if there may be a burn mark under one of teeh relays. Based on your elimination of the other issues I wonder if the heater relay board could be your issue. Quote Link to comment Share on other sites More sharing options...
