Display shows Hi or 'High Temp' and grill overshoots set temperature

Safety first: If temperature is extremely high or there is a grease fire, turn the grill off, unplug it, and keep the lid closed until the fire subsides. Do not use water on grease fires.

• Clean grease: After cooling, thoroughly clean the drip tray, grease channels, and cook box to remove flammable grease buildup.
• Check pellet feed: Observe whether pellets continue to feed when the set temperature is reached. If the auger runs constantly, the control board or auger relay may be stuck.
• Inspect RTD probe: Clean the RTD probe and ensure it is properly mounted and not touching metal surfaces that could skew readings.
• Test with lower setpoint: Set a low temperature and monitor. If the grill still overshoots significantly, replace the RTD probe. If the issue persists, the control board may need replacement.
