pMak26 Posted September 21, 2017 Report Share Posted September 21, 2017 Hey guys, looking for some technical support. I'm retrofitting a new S-class Gecko spa pack to my 2001 Gulf Coast spa. Once installed, the display screen backlight turns on, but the display does not show anything. Further, the buttons on the panel do not control the indicated items. For example, hitting a button such as the light button turns the blower motor on. Hitting the arrow down button turns pump 1 on. None of the functions are correct. So, I tried a brand new panel, same issue. I have tried changing the jumper position with no change. The display continues to not work. So, I tried to replace the brand new S-class Gecko spa pack with another one, same issue persists. The old control pack is no longer available. Here are my tub specs: 240v - line 1, neutral, ground, line2 2 pumps Blower Ozone Does another have a clue as to what could be going on? I'm desperate for some help!

Tperk Posted September 23, 2017 Report Share Posted September 23, 2017 Does new board have DIP switches? May be a DIP switch setting or a jumper that needs to be set correctly. Quote Link to comment Share on other sites More sharing options...
