Question about Pentair Minimax NT Heater
I would say the problem is the thermistor. The board will light up, the SW switch is green, but you get a display that flashes dashed lines and then what looks like 888. That is a start up code. The thermistor is located on the side where the water enters the heater. There are two screws at the top of the side panel. Undo the screws and lift the panel off. The thermistor is a probe with 2 small wires coming out and lead to the control panel. It is a very simple fix and is usually the problem if you have not experienced any other issues. The part runs between 30 and 45 dollars. Most pool stores would carry this.
thanks let me know if that fixed the problem
