Pentair MasterTemp 250 Control Board unresponsive

Postby vonitsa » Wed 25 Oct, 2017 18:50

I have a Pentair MasterTemp 250 which had a fried fan and didn't want to start.
I shorted pins 1 and 2 of the control board and the heater started (of course I had to replace the fan motor).
It works fine now, heats and all the goodies but all the buttons are unresponsive. I have to turn the heater on and off from the breaker on the wall, all lights work fine except one thing: The Spa ON light stays On instead of the Pool ON light (heater works fine on this setting)
Do I need a new control board (since it has been shorted) or a Switch Membrane? Is there a way to reset the board?
Please help...

Not my topic unfortunately Vonista, I bet you have already answered your own question and its the more expensive answer.

Hi Vonista
Have you tried asking the manufacturers
