Help! My pool heater isn't turning on— here are some tips to get it working again.
Why is my Hayward gas pool heater not heating?
Here's a helpful overview of some common reasons your Hayward H Series pool heater might not be working properly. Hopefully, this helps you troubleshoot easily!
If your heater attempts to start but doesn't, or if you see an "IF" (Ignition Failure) code, don't worry—sometimes it's something simple, like the gas supply valve being turned off. It could also be caused by cobwebs blocking the orifices or issues with the flame sensor, igniter, or gas valve. Remember, these are common problems, and we’ll find solutions to get everything working smoothly again!
If your heater displays a “LO” error code, it usually means there's a low water pressure issue. You might want to start by cleaning the filter and checking that the pump is working properly, making sure water is flowing smoothly. If these steps don't resolve the problem, it could be related to the pressure or limit switch. Our friendly, certified gas technicians are here to help you anytime.
If your heater isn’t starting at all and shows a "CE" code or no display, it might be a communication issue between the main control board and the keypad. This could be caused by moisture behind the keypad, but unfortunately, it could also be related to an electrical issue or a faulty control board. Luckily, we carry common Hayward replacement parts to help get your heater back up and running quickly!

Why is my Jandy JXI gas pool heater not heating?
Here's a helpful overview of common reasons why your Jandy pool heater might not be working. Hopefully, this simplifies the troubleshooting process!
If your Jandy heater displays a “FAULT CHECK IGN STEPS” ignition failure error code, don’t worry—this is a common issue that our experienced gas heater technicians often encounter. Usually, it points to a problem with the igniter, air pressure switch, a dirty flame sensor or improper gas supply. Since you're dealing with electrical components and gas, it's safest to let us take care of this for you, ensuring your family's safety and peace of mind.
If you see a “FAULT –HIGH LIMIT” error code on your Jandy heater, it likely means the water temperature has gotten too high, or there’s a problem with the high-limit switch. Our friendly technicians know just what to do—whether it’s checking the high-limit switches, tightening loose connections, or replacing them if needed. They’ll also check the temperature rise inside the heater and find the cause of any overheating, so your heater can get back to working smoothly.
If your Jandy heater shows a “NO FLOW” error, it usually means water pressure is low. Try cleaning the filter and make sure the pump is working well so water can flow smoothly. If the problem continues, it could be related to the pressure switch. Our friendly, certified gas technicians are always here to help you out whenever you need it.

Why is my Raypak gas swimming pool heater not heating?
Here's a helpful guide to some common reasons why your Raypak pool heater might be acting up. It clarifies what Raypak's fault codes mean and offers simple solutions to get things back on track. Hopefully, this makes understanding error codes feel more approachable and less stressful for you!
If your Raypak heater shows a “Rollout Sw Open” error, don’t worry—this is a common problem that our friendly Raypak gas heater technicians often see. It means the flame is rolling out of the heat chamber near the burners. Usually, it’s caused by a blocked or sooted heat exchanger, venting issues, or windy weather. A clogged burner tube or orifice can also lead to this error. Since you're working with electrical parts and gas, it's best to let us handle it for you—keeping your family safe and giving you peace of mind.
If you see a “High Limit 2 Fault” error code on your Raypak heater, it likely means the water temperature inside the heat exchanger has gotten too high, or there’s a problem with the unitherm governor, and or the internal bypass Our friendly technicians know just what to do—whether it’s checking the these devices, or replacing them if needed. They’ll also check scale build up inside the heat exchanger tubes and find the cause of any overheating, so your heater can get back to working smoothly.
If your Raypak heater shows a “Water Sw Open” error, don't worry — in most cases, it’s not a heater problem at all! It usually means that water pressure is a bit low. Try giving the filter a good clean and ensure your pump is running smoothly so water can flow without any hiccups. If the issue persists, it might be related to the pressure switch. Remember, our friendly, certified gas technicians are always here to help you out with your Raypak heater whenever you need a hand.
