Product details

The Hayward IDXLFLS1930 is the genuine flame sensor for the Universal H-Series Low NOx heaters, models H150FD through H400FD, and for the earlier H-Series Low NOx 250 and 400.

What it does

Once the ignitor lights the burner, the flame sensor confirms to the control board that a flame is present. Without that signal the board closes the gas valve within seconds. A heater that lights, runs briefly and drops out, then retries, is the classic sign.

Clean before you replace

A coated sensor rod gives the same symptom as a failed one, so it is worth cleaning the rod first. If the fault continues, fit this sensor. The ignitor is a separate part.

Questions and answers

What people ask about this product, answered by our pool techs.

Which Hayward heaters use this flame sensor?
The Universal H-Series Low NOx models H150FD, H200FD, H250FD, H300FD, H350FD and H400FD, and the earlier H-Series Low NOx 250 and 400.
What does a failing flame sensor look like?
The heater ignites, runs for a few seconds and shuts down, then retries. The board is not seeing proof of flame. Try cleaning the sensor rod first; if the fault continues, replace it.
Is this the same as the ignitor?
No. The ignitor lights the burner and the flame sensor confirms it is lit. They are separate parts, and the H-Series ignitor kit is sold separately.
Is this a genuine Hayward part?
Yes. It is Hayward part IDXLFLS1930.
