How to Fix Error Code 25

  1. Power Off the System

    Always disconnect power before working on HVAC equipment to avoid electric shock or injury.
  2. Inspect the Fan Blade

  3. Check the Fan Motor Wiring

    Capacitors can store dangerous voltage even after power is off. Discharge the capacitor before touching motor terminals.
  4. Test the Run Capacitor

    Capacitors can store a lethal charge. Wait 5 minutes after power-off and use a discharge tool or resistor to safely discharge it.
  5. Inspect the Fan Motor Reversing Relay (if applicable)

  6. Verify Control Board Signals

    Working on live circuits is dangerous. Only proceed if you are qualified; otherwise, call a professional.
