What causes a gas heater to not stay lit?
What causes a gas heater to not stay lit?
Some common causes include issues with the thermocouple and pilot tube. The thermocouple detects the pilot light via sensors. A dirty pilot tube can also prevent the pilot from staying lit. If the pilot tube is dirty, let the furnace cool down and turn off the gas.
How do I reset my Hayward H series pool heater?
The heater can be manually reset using the keypad by cycling the MODE button through “STANDBY” and back to the original operating mode (“POOL” or “SPA”).
How long should a gas pool heater last?
With proper installation and maintenance, gas pool heaters typically last five or more years.
Why is my Hayward H250 pool heater not starting?
For example, the heater should not startup unless the pump is running and water is flowing through the heater. If you are doing this test with the pump off, you can jump across the flow sensor and the heater may start, but the flow sensor is correctly detecting the lack of flow.
What should I do if my Hayward gas heater won’t light?
Fyi, I DID leak-test before attempting to light anything after re-assembly, and can confidently say there were no leaks. You should remove the tubing starting from the gas valve and then once off the heater blow it out with a little compressed air. If you still have a weak lazy flame, replace the entire assembly.
Is the Hayward pool heater made of gas?
The components of a Hayward pool heater are also very similar to gas heaters made by other manufacturers. To troubleshoot a gas-fired appliance, you have to think like a “combustioneer”.
What should the pilot be on a Hayward heater?
Ideally a thermopile should be putting out 750 mv. Most heaters will work down as low as the 350-400mv range. 2) The pilot is a bright orange flame, like a candle, not blue as I suspect it should be.

Why does the pilot light on my Hayward heater not stay lit?
I have a Hayward H250 millivolt heater (natural gas), and the pilot won’t stay lit when the button is released. 1) The thermopile seems to be putting out very little voltage – when first lit it starts around 8mv, and after 2 minutes only reaches 18mv. 2) The pilot is a bright orange flame, like a candle, not blue as I suspect it should be.
