Controller displays LERR or LOW TEMP and cannot reach set temperature

Safety first: Use heat-resistant gloves when adjusting vents or inspecting the cook chamber during operation.

• Check pellet quality and level: Ensure the hopper is at least half full with dry, high-quality pellets. Remove fines and dust from the hopper bottom.
• Inspect firepot: With the grill cool, clean ash and clinkers from the firepot to ensure good combustion.
• Verify fan performance: Start the grill and listen for strong, steady airflow from the combustion fan. Replace the fan if it is weak or intermittent.
• Reduce heat loss: In very cold or windy conditions, use a Yoder thermal jacket if available and position the grill out of direct wind. Avoid frequent lid openings.
• Check RTD probe: Inspect and clean the RTD probe. Heavy buildup can insulate it and cause incorrect readings. Replace if damaged.
