SOURCE: Pool heater will not heat
Im no pro, but I know there is an air sensor behind the main board. If the fan is running you probably have a problem with that sensor. If your lucky the air hose could have just popped off.

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.

If the fan was seized, it is likely bad, even if you freed it. If it doesn't sound the same, or is not as loud as it used to be, it is also most likely bad. If it doesn't move enough air to close the air pressure switch, then you will get an 04 fault, which is an air flow fault. HTH

For most pool heaters, if they will not start up in the spring, the problem is corrosion in the wiring somewhere... I would remove and clean all wiring connections and then try. The amount of current is very small and so any bit of corrosion can cause the unit not to work.
It all so could the t-stat again, but you would need to check that with an OHM meter. No continuity when the heater should be on will confirm that the t-stat is bad...
