Display shows “HEr” (High Error) and grill shuts down during cook.

Safety first: Treat this as a potential grease fire. Turn the grill OFF, unplug it, and keep the lid closed until flames are out. Never use water on a grease fire.

• 1. After cool-down, deep clean:
  • Remove grates, drip tray, and heat baffle.
  • Scrape and remove all heavy grease from the drip tray and barrel.
  • Vacuum ash from the firepot and bottom of the grill.
• 2. Inspect auger feed:
  • Check that pellets are not overflowing the firepot.
  • If the firepot is heaped with pellets, the auger may be overfeeding due to a stuck relay or controller fault.
• 3. Check RTD and controller:
  • Clean the RTD probe of soot and grease.
  • If HEr occurs at normal cooking temps, test/replace the RTD.
  • If a new RTD does not fix it, replace the controller.
• 4. Prevent recurrence:
  • Empty the grease bucket regularly.
  • Line the drip tray with foil and clean it frequently to prevent grease buildup.
