i have an older LB spa and the control panel will cycle thru the turbo air button taking 3-4 times to show the blower off but the blower keeps running. the blower is nosey and really churns water
haven't found a way to cut it off besides unplugging wires from box. where do i start for prob?
thanks bunches

The Triac chip is blown. It's the little guy that enables the three speeds on the blower.
I always replace the entire main board (much to the consumer's dismay) however some
other post have suggested re-soldering a new triac on. Maybe some one else will follow
up with that please.
