firedude Posted May 29, 2022 Report Share Posted May 29, 2022 My 15 y.o. Lazboy Limited runs but the blower is constant on, creating noise and steam constantly. It's a old spa but I figure the malfunction is likely caused by the topside controlle which, by now, the LCD is gone and the buttons don't do much. My Gecko controller is labelled K600-DG with options GF-KDG-SP-NO and, as far as I can, the current models need "reprogramming" to function with the older spa. Is there a direct replacement for this controller? And does the blower constantly running sound like its a problem with the control panel? Thanks for any time you take to help me!

Couch67 Posted May 30, 2022 Report Share Posted May 30, 2022 could be, but its more likely a stuck relay in the spa pack and not the topside. You could try to unplug the topside from the spa pack and power cycle the spa to see if the blower turns off. What kind of spa pack do you have?
