How to Fix / Troubleshooting
Safety first: Unplug the grill before inspection. Do not work on the controller while it is connected to mains power.
- 1. Disconnect accessories:
- Unplug any meat probes, WiFIRE antenna modules, or accessory harnesses from the controller.
- Plug the grill back in and power ON. If ERR disappears, reconnect accessories one at a time to find the faulty item.
- 2. Visual inspection of controller:
- Remove the controller from the hopper housing.
- Look for burn marks, bulging capacitors, or melted areas on the circuit board.
- If visible damage is present, the controller must be replaced.
- 3. Check wiring harness:
- Inspect the main harness from controller to auger motor, induction fan, and hot rod.
- Look for pinched, melted, or chewed wires that could be shorting.
- Repair or replace damaged harness sections.
- 4. Replace controller:
- If ERR persists with all loads disconnected and wiring intact, install a new OEM Traeger controller compatible with your model.
- Label each connector before removal to ensure correct reinstallation.
