How to Fix / Troubleshooting

Safety First: Disconnect power before accessing internal components.

  • Power cycle: Unplug the dryer for at least 10 minutes to allow the control to fully discharge. Restore power and attempt to start a cycle.
  • Check power quality: Verify the outlet voltage is stable and within specification using a multimeter. Avoid using long extension cords or power strips.
  • Inspect control board: Remove the top panel and inspect the main control board for obvious damage, burnt components, or corrosion.
  • Connector check: Reseat all harness connectors to the main control board to ensure good contact.
  • Replacement: If F03 returns consistently, the main control board is typically replaced. Use the exact Whirlpool replacement part and transfer any jumpers or settings as specified in the service sheet.
  • Test: After replacement, run a diagnostic cycle (if available) and a normal drying cycle to confirm proper operation.
