Display shows L1 and grill struggles to reach or maintain low temperatures; may extinguish at low settings.

Safety first: Allow the grill to cool before internal inspection.

Steps to improve low-temp performance:

• Use high-quality pellets: Fill the hopper with dry, food-grade hardwood pellets. Avoid pellets that are dusty or crumbly.
• Clean fire pot and burn area: Remove ash and clinker buildup from the fire pot to ensure consistent ignition and burn.
• Check fan operation: Verify the combustion fan is not running at full speed constantly at low settings. If it is, the control board may be misdriving the fan.
• Inspect RTD placement: Ensure the RTD probe is not directly in the path of incoming cold air or touching metal surfaces that could skew readings.
• Controller calibration (if available): Some Royal Gourmet models allow temperature offset adjustment. Follow the user manual to calibrate the displayed temperature to match an external thermometer.
