Very greatful for this forum, and Pool Clown taking the time to help.
I have a Jandy 1400, 3 port, just under 2 years old for a fiberglass 10,000 gallon pool.
Getting the 172/186 error codes.
I've cleaned the sensor with the green pad, but not acid wash.. even re-seated the connector on the circuit card.
I'm a controls tech, so I'll run through the trouble shooting manual.
I guess what gets me is that the sensor doesn't have moving parts... If I buy a new one, I'll be taking the old one apart to see what is going on.
It'd be nice to have a home remedy to fix sensors..
