Re: Pentair minimax ch Heater Problem.
same problem, same heater; haven't had anyone out to look at it yet; I cleaned off the terminals of the pressure switch after reading this post, and tried to fire it up...no luck. Frustrated, so, like in the movie Armageddon (the cosmonaut, remember) I wacked the pressure switch with the handle of the screw driver and abracadabra, the thing fires up! I came back a couple of hours later, and it was not working. Gently tapped the pressure switch, and it fires on again. Does it sound like my problem and I should replace?
