Possible Causes
Overcurrent on one of the outputs (auger, fan, igniter), Internal control board sensor fault, Shorted wiring harness, Intermittent connection on control board
How to Fix / Troubleshooting
Safety first: Disconnect power and allow the grill to cool before inspection.
- Inspect wiring harness: Open the service panel and visually inspect all harnesses from the control board to the auger motor, igniter, and fans. Look for melted insulation, pinched wires, or exposed conductors.
- Check each load: Disconnect one component at a time (igniter, auger motor, combustion fan) and attempt to start the grill to see if Er9 disappears. This can help identify which circuit is causing the fault.
- Replace faulty component: If the error clears when a specific component is unplugged, that component is likely shorted or drawing excessive current and should be replaced.
- Secure connections: Reseat all connectors on the control board to ensure good contact.
- Control board replacement: If no single component is at fault and wiring is intact, the main control board may have an internal defect and should be replaced.
