When your Hayward H-Series heater fails to light, a worn or failed ignitor is often the culprit. The IDXIGN1930 is the correct OEM-spec replacement ignitor for the H100ID1 natural gas and H100IDP1 propane pool heaters -- restoring reliable ignition so your heater fires consistently every time.
Pool heater ignitors wear out over time through normal cycling, moisture exposure, and carbon buildup. If your H100ID1 or H100IDP1 clicks but won't light, produces a weak spark, or shows no ignition activity at all, the IDXIGN1930 is the direct replacement part to reach for first.
This is a genuine Hayward replacement component, engineered to match the original ignitor specifications for the H100 series. No adapters, no fabrication -- it installs in the same location as the original and connects with the existing wiring harness.
Engineered to the same spec as the original ignitor in Hayward H100-series heaters. No modifications required.
Works with both natural gas (H100ID1) and propane (H100IDP1) versions of the H100 heater.
Weighs just 0.05 lbs. Easy to handle during installation and won't stress surrounding mounting hardware.
Replaces a failed or degraded ignitor to bring your heater back to its normal auto-ignition operation.
The IDXIGN1930 is specifically listed for the following Hayward H-Series heater models:
If you own a different H-Series model (H150, H200, H250, H300, or H400 series), confirm your specific model number against Hayward's parts diagram before ordering, as ignitor part numbers vary by heater capacity and generation.
The ignitor is located inside the heater cabinet near the burner assembly. Before beginning any work:
The ignitor typically connects via a push-on or spade-style connector to the control wiring. Refer to your heater's existing wiring layout before disconnecting the old unit so reinstallation is straightforward.
Ignitors in pool and spa heaters are subject to repeated thermal cycling, outdoor humidity, and occasional water intrusion. Common signs of ignitor failure include:
