Display shows ERR LO or low temperature alarm; grill cannot reach or maintain the set temperature and may shut down.

Safety first: Turn OFF and unplug the grill before cleaning or accessing internal components. Allow it to cool.

Steps to address ERR LO:

• 1. Check pellet supply: Ensure the hopper is at least half full with dry, premium hardwood pellets. Replace any pellets that appear swollen or crumbly.
• 2. Inspect the fire pot: Remove grates and diffuser, vacuum ash from the fire pot and surrounding area. A heavily ashed pot can smother the flame.
• 3. Verify auger feed: During startup, observe whether pellets are dropping into the fire pot at regular intervals. If feed is weak or intermittent, inspect the auger for partial jams.
• 4. Check combustion fan performance: Listen for a strong, steady fan sound. If airflow seems weak, clean intake vents and consider inspecting the fan for obstructions or failure.
• 5. Shield from wind: Strong wind can strip heat from the cook chamber. Position the grill in a more sheltered location and avoid opening the lid frequently in cold weather.

If ERR LO continues despite good pellets, a clean fire pot, and proper airflow, the auger motor or control board may require professional diagnosis.
