SOURCE: Pentair Minimax NT 400 heater. fan keeps coming
Sounds like the controller is the problem. This is the circuit board that has the display and controls on it. You can swing that panel open and try tapping on the white plastic cover the controller is under that. This might get the fan relay to release but you will have to replace the controller it will stick again

I had the same situation in FL. Rats ate the wiring harness. Take off the cover panel and visually inspect.

This is a fan falure code. It can mean the fan has problems (not likley if the fan goes and isn't labored) You have a sensor in your exaust (probally not this if you don't get a good start) The culperet is probally in the negetive pressure sensor. This is a 2-3 inch disc with wires going to the controls and a rubber tube going to the fan. Pull the tube from the fan and make sure the fan fitting is clear (poke with a tooth pic) Be sure their are no kinks in the hose. If the heater is 4 years old the diaprahm could be bad in the pressure sensor. Check the other things first but this is probally your problem. Good luck, hope this helped.

Probally the easyest convertion on the market. Where your gas line comes in the heater the line loops up over and down. There are two unions on this at the base of the loop. take these apart and their is a washer in one and you replace it with the Propane washer and put back together.
