Often that is because of a bad or dirty flame sensor...The flame passes a current through the flame and theat proves that there is flame... if the flame is not hitting the sensor or it is dirty it will not pass the current through... also check that the burner ground is not corroded or loose...

These can be a bugger to fix...
and sometimes it turns out to be a bad sensor or a bad ignition module...

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.

My pool heater wont start the pilot light is on the red light is blinking and the fuel tank is full the temp. Is on high .the burners came on for asecond and then shut off?????what should i try to do now??

With these pool heaters, there are a couple things that you can check yourself before you call a pro for this problem. Try cycling the ignition sequence until all air is out of the gas line. Also, check your gas valve. If it is manfunctioning, it will need to be replaced.

Have pilot but burner will not start. Gas line is

There is an internal pressure switch for this unit that must sense water pressure before the gas valve solenoid is energized so that burner will light. If the air line to the pressure switch is leaking or has failed or is blocked it will not light at all. Additionally if you have had mice or smaller rats get into the unit, check the wiring to the pressure switch for any signs of damage. They can cause havoc! (Personal experience)

If you need further assistance please include your exact model number of your pool heater in your response.

Thanks for using FixYa.

Make sure your pool filter is clean. Low water flow through the heater will be detected by water pressure switch

Heater won't stay lit

On your main gas manifold you have orfaces that screw into it at each burner. Remove these and see if their are small spider webs in them. They will look like little lint balls. They can keep your main burner from getting gas and in turn keep the heater from sensing flame. The pilot lights and the heater starts but no flame at the main will shut it rite down. See if this helps.
