Display shows PrE or "Preheat" error and grill cannot reach set temperature during startup

Safety first: Ensure the grill is stable and on a level surface before troubleshooting.

• Confirm lid position: Always preheat with the lid closed. An open lid can prevent the grill from reaching preheat temperature.
• Check pellet quality and level: Use dry, hardwood pellets and ensure the hopper is at least half full.
• Inspect combustion fan: Listen for strong airflow during preheat. If airflow is weak, clean the fan and air passages and verify the fan is running at full speed.
• Clean fire pot and burn area: Excess ash can smother the flame. Vacuum the fire pot and surrounding area.
• Verify temperature sensor: If the grill is clearly hot but the display shows low temperature, inspect and test the RTD probe and replace if necessary.
