Make sure the pipes are full of water. Check the thermostat to see if it is calling for heat. Make sure the thermostat is set to a temperature higher than the current temp of the water. If all those things are Ok then the unit may have gone off on high limit the last time you used it or the gas valve coils may have to be replaced. If there is a reset button for high limit press it. If not then the safety sensor for high limit may have to be replaced. If the unit fires up but does not stay on then the gas valve coils may need to be replaced.

Pool Heater. Hayward H100ID Starts fine and heats for about 5 minutes. Then heat stops. You can feel the blower its just cold air.

It sounds like your pool heater is not firing. I would check several things: the burner might be blocked and clogged, the gas valve might need to be replaced, the direct spark module might be malfunctioning, or the combustion blower might be cleaned. One of these is probably the issue. A service man can repair all of these problems.
