The circuit boards in the M-Class controllers from Gecko can be replaced instead of replacing the whole controller. The Gecko M-Class controller is the largest most robust controller Gecko made for spas and swims spas.


The M-Class was used some hot tub manufactures in larger spas and swim spas, some of the hot tub brands that used the M-Class in some of there larger spa models are Older Coast Spas, some larger Arctic Spas pre-2005.


The Gecko replacement circuit boards for these units are very specific and replacement must be selected by the part and chip number to ensure proper function.
