Navien Ignition Transformer 30011323A

The Navien 30011323A is an ignition transformer used in Navien NPE-AWE and NPE-SWE series boilers. It generates the high-voltage supply that produces the spark at the ignition electrode during a call for heat. The transformer sits within the boiler's ignition circuit and works alongside the electrode and its leads to light the burner.

• The boiler attempts to fire but there is no spark at the ignition electrode
• Repeated ignition lockouts on start-up, with the fan and gas valve operating normally
• Intermittent ignition, where the burner lights on some attempts but not others
• No audible sparking or a weak, irregular spark when the ignition sequence runs
• Ignition faults that persist after the electrode and its leads have been checked

• Confirm your boiler model against the fit list above
• Check the serial number of your appliance, as fitment is listed against specific serial numbers
• Verify the existing transformer's part number before removing it
• Inspect the ignition electrode and leads for damage or contamination, as these can cause similar symptoms
