Grill temperature swings widely above and below the setpoint

Safety first: Avoid touching hot surfaces while the grill is running.

• Clean RTD probe: With the grill cool, gently clean the temperature probe with a non-abrasive pad to remove grease and soot.
• Use quality pellets: Switch to a reputable brand of hardwood pellets with consistent size and low dust.
• Adjust P-setting: If your controller supports it, fine-tune the P-setting to better match ambient conditions (slightly higher in cold, lower in warm weather).
• Seal leaks: Inspect the lid and body seams for gaps. Install high-temperature gasket material where needed to reduce drafts.
