Pentair Minimax NT power light of, Pressure SW on

[Rashidy_chem]

Very nice forum!

My Minimax NT power light is off. LED is blank. Only pressure SW light turns on when the pumps is running. All other lights are not turning on.

Transformer is working fine. I have 26VAC on orange/white.

Any ideas what could be wrong?

Thanks

Is this connected into any automation system?

No... Its just the timer. (Intermatic time swithc). When switch us on the Pressure SW light turns on and still power light is off!

Well it is possible that the board is bad. Other than swapping it out, no real way to test it.

Have you checked all of the wiring inside to make sure nothing has been chewed or became disconnected?

Yes I checked... All good.
When I bypass the board the heater start working...
I ordered a new board ( refundable ) to test. Expensive!
