Display shows P5 and grill overshoots set temperature and cycles between very hot and cooler periods.

Safety first: Make control adjustments with the lid closed and away from hot surfaces.

Steps to adjust:

• Lower P-setting: Decrease the P-value (or equivalent) one step at a time to reduce pellet feed during idle cycles.
• Check exhaust: Ensure the chimney cap is properly adjusted and exhaust ports are not blocked.
• Use consistent pellets: Stick to one brand and size of pellets to maintain predictable feed behavior.
• Verify with thermometer: Use an external probe to confirm that temperature swings narrow after adjustments.
