tym2ride Posted July 21, 2018 Report Share Posted July 21, 2018 I have a 2012 Hot Spring Limelight bolt. It always worked fine. The other day I went to clean it and the display was blank. I checked all the power to it and there is 220v and 110v connected to the relay board in the IQ2020 box. I removed the small relay board in the box and there are NO burned looking areas. There are 3 jumper wires going from the relay board to the main board (Red White Black) and they are supplying 110v to the main board. There are no led lights lit on the main board and the power terminals to the circulator pump have no power. I am trying to comfirm if it is the circuit boards in the IQ2020 box or the top mounted control. Anyone have any ideas? Thanks Quote Link to comment Share on other sites More sharing options...
castletonia Posted July 22, 2018 Report Share Posted July 22, 2018 If the relay board has burn marks, it’s fried. There could be other issues, but until you replace the relay board, you won’t know. Quote Link to comment Share on other sites More sharing options...
