How to Fix / Troubleshooting
Safety first: Unplug the opener before touching any internal electronics.
- Power reset: Disconnect power for at least 60 seconds, then plug back in. Sometimes a full reset clears transient faults.
- Check power source: Verify the outlet has correct voltage (typically 120 VAC in North America) using a meter or by plugging in another device.
- Inspect board visually: Remove the opener cover and inspect the logic board for burn marks, swollen capacitors, or corrosion. If present, the board is likely damaged.
- Surge protection: If the fault occurred after a storm or outage, install a surge protector on the opener circuit after replacing the board.
- Board replacement: Replace the logic/control board with the exact Wayne Dalton part number for your model. Transfer all wire connections one at a time to avoid miswiring.
