SOURCE: Our H Series pool heater is igniting but is not

This could be a bad thermostat or temp sensor, or it could be a water flow problem. Ether the by-pass in the heater or on the outside pipes. It could just be the filter is dirty expecally if it is a DE filter. These should be taken apart and cleaned at least once a year. I hope this helps.

Many things without more info, but if your new at this let's go with simple. Make sure your baskets are clean and your filter is clean. Without proper water flow the heater would overheat and boil the water inside. Because of this it has safty switches to stop it from running when things get dirty. Good luck and let me know how you do.

Yes this should be a warrenty part so long as no water is leaking in the heater and getting to it.

Just had our circuit board on H400FD Haywood pool heater replaced. Heater did fire up but wouldn't go past 65 degrees and went to standby.

It may be wired incorrectly, there are 3 terminals for the Hayward heater that connect it to automation.

1 spa
2 pool
3 comm

If they are not wired correctly this issue can happen.

Intex purespa displays current water temp but will not turn on or start filter/bubbles. Bought 1 mo ago: just set it up a week ago. Was working fine for 1 week. TrI'd unplug and reset. Any ideas??

is displayed temp less than 2 degrees than setpoint temperature ? its possible this situation will disallow the pump to go to high speed and the air infusers to work till spa heats back up , or can be a heater fault as well

Allheaters run off of a thermostat just like the heat to your house. It will shut off once heated to the selected temperature. Turn up the temperature, and monitor it for a couple days.

Pool heater runs but the air coming out of the unit is cold.

R3 is not one of the actual error codes, but is part of the computer system. What you can try to do is reset the computer in the heater. First you will need to turn the heater off, then turn off the circuit breaker for the heater. Wait about 15 to 20 minutes then reverse the order, the circut breaker then the heater. Try and start the heater and watch the display panel.

If they R3 reappears, then the problem is the control board for the heater and it will need to be replaced.

I shut off the gas to the unit and the power.i

No, that does not seem correct. If all you did was replace the heat exchanger, then tried to start it up, how could everything go wrong. Unless there was another issue with the heater. Not too many people change out the exchanger, unless corrosion has caused a leak there What you CAN try to do is reset the heater. To do this, turn off your heater first-at the toggle switch inside the right hand side door, then turn off the circuit breaker to the heater, wait about 5 to 10 minutes, then reverse the order. Circuit breaker then heater, if you have the digital display, you will see flashing codes, this is the computer resetting, then you should see the normal display. Try starting the heater again. If it still will not fire, let me know if you receive an error code. Also, check to see if the temp the heater is reading is close to that of the actual water temp.
