Gecko S-Class air turns on by itself every couple days randomly

[jimiamoore]

It's not the jets or any sort of timed cleaning cycle. It's the air. It just randomly turns on. I have a keypad with it. What should I do to troubleshoot?

Welcome to TFP!!!

Sorry you have not gotten any help, but this is a weird one

So this tub has a separate pump/fan just for the air? Many hot tubs just draw in air using the jet water flow through a venturi.

Does it still happen if you disconnect the control-panel from the pack?
You probably have a faulty panel or board.
One thing to try though would be a clean of the board as it looks to be absolutely filthy. A short in the right place would absolutely be able to turn on the blower, but one in the wrong place could cause the board to be fried or even a fire.
