Possible Causes

Failed hot surface ignitor, Broken ignitor wiring harness, Faulty relay on Thermo Pride control board, Low line voltage

How to Fix / Troubleshooting

Safety First: Turn off power before handling the ignitor. The ignitor is fragile and can break easily.

  • Visual inspection: Remove burner access panel and locate the ignitor. Look for cracks or breaks in the ceramic or element.
  • Continuity test: Disconnect the ignitor plug and test for continuity with a multimeter. An open circuit indicates a failed ignitor.
  • Replace ignitor: Install a Thermo Pride-approved replacement ignitor, avoiding contact with the element. Use the original bracket and maintain the same position.
  • Check wiring: Inspect the harness from the board to the ignitor for burns or loose connections.
