How to Fix Error Code 14

  1. Turn off power and gas supply

    Always disconnect power and gas before servicing. Gas leaks can cause explosions or carbon monoxide poisoning.
  2. Check gas supply and connections

    If you smell gas or detect a leak, leave the area immediately and call your gas company.
  3. Inspect the flame sensor

    Handle the flame sensor carefully as it can be easily damaged or bent.
  4. Clean the igniter

    Do not touch the igniter with bare hands or use abrasive materials that could damage the ceramic surface.
  5. Check gas valve operation

    Do not attempt to adjust or repair the gas valve yourself as this requires professional expertise.
  6. Inspect the pressure switch

    Never bypass pressure switch safety devices as they prevent dangerous operating conditions.
  7. Reset the system

    Stay near the unit during the first ignition cycle to ensure proper operation and be ready to shut off gas if problems persist.
