thanks a lot, sprayed with silocone spray, worked back with screwdriver and it worked, keped working switch high low high low a alot of times works good thanks again, I just got this hot tub about a week ago got no manual with it ,it a great lakes model huron 1996, I dont know how the timer works, it has little fingers on the out side, and a cloucklike hand on the in side, was woundering how to set it, any help would be helpfull. thanks .

the fingers push toward the center for the "on" setting. Adjusting is a personal preference. It's there to save money, so you don't have the filter/heat cycle all the time. I would set a minimum amount of time required to keep the tub at usable temp. Break up the time throughout the day.
