Controller display shows ER-7 and grill shuts down or will not maintain temperature; fan may not run.

Safety first: Unplug the grill and allow it to cool completely. The fan area may have sharp edges; wear gloves.

Steps to troubleshoot ER-7:

• Listen for fan operation: During startup (before unplugging), note whether you hear the combustion fan running. A silent fan with ER-7 indicates a likely fan or power issue.
• Access the fan: Remove the side or bottom access panel to locate the combustion fan assembly. Inspect the fan blades for grease buildup, debris, or foreign objects that could block rotation.
• Spin test: With power disconnected, gently spin the fan blade by hand. It should rotate freely without grinding. If it is stiff or seized, the motor is likely failed.
• Check wiring: Trace the fan wires back to the controller. Ensure the connector is fully seated and that there are no burned or melted sections of wire.
• Replace fan if needed: If the fan is seized or the motor shows signs of overheating, remove the mounting screws and install a new Recteq-compatible combustion fan assembly. Ensure correct orientation for airflow.
• Re-test: Reassemble panels, plug in the grill, and start a cook cycle. Confirm that the fan runs continuously during ignition and that ER-7 clears.

Note: If a known-good fan does not run and ER-7 persists, the controller's fan output circuit may be defective and the controller should be replaced.
