Possible Causes

Defective gas valve modulating coil, Broken wiring to gas valve, Faulty control board gas driver, Incorrect gas valve calibration

How to Fix / Troubleshooting

Safety: Gas components must only be serviced by qualified personnel. Turn off gas and power before any work.

  • 1. Reset and test: If A14 appears immediately on demand, the control cannot modulate the gas valve.
  • 2. Visual wiring check: Inspect the gas valve connector and wiring harness for damage or loose pins.
  • 3. Technician diagnostics: A professional should measure coil resistance, verify supply voltage during operation, and check gas pressures.
  • 4. Replace gas valve if faulty: If the valve does not respond to modulation signals or is out of calibration, it must be replaced and adjusted using a flue gas analyzer.
