Pentair Minimax NT problem

Posted by katshot (My Page) on

My heater is approx. 7 years old. Was working fine but, when I went to turn it on yesterday, nothing. Green power light is on but, when I click the switch to either pool or spa, nothing happens. No fan, no nothing.
What should I check first?
Also, I have read some posts concerning these heaters that suggests that they have a digital readout that can provide diagnostic trouble codes. Mine has no such feature that I'm aware of.

Have you backwased your filter?

Recently? No. Why would that matter? Pressure and flow are fine.

If you open the heater door you will see a little black box called a Fenwall there is a light on it that may be flashing count the flashes and in the door there should be a code listing telling you the problem based on the number of flashes.
