How to Fix / Troubleshooting
Safety first: Turn OFF and unplug the grill before opening any control housings.
Steps to troubleshoot ERR COMM:
- 1. Power cycle: Unplug the grill for 5 minutes, then plug back in and power on. Temporary glitches can clear with a reset.
- 2. Inspect control connections: Remove the front control panel bezel as needed to access the display and main board. Check that ribbon cables and harness connectors are fully seated and free of corrosion.
- 3. Look for moisture: Signs of condensation or water inside the control housing can cause intermittent communication errors. Dry the area thoroughly and correct any gasket or seal issues.
- 4. Check for physical damage: Cracked display boards or burned components on the main board indicate the need for replacement.
- 5. Replace the affected board: If reseating cables does not resolve the error, replace the display module or main control board with Twin Eagles-approved parts. Label and transfer each connector one at a time to avoid miswiring.
