Display shows HEr and grill temperature spikes well above the setpoint or shuts down due to overheat.

Safety first: If you suspect a grease fire, keep the lid closed, unplug the grill, and use a Class B or K fire extinguisher if needed. Do not open the lid until flames subside.

• Step 1 – Allow full cool-down: Wait until the grill is completely cool before inspecting.
• Step 2 – Deep clean grease system: Remove grates, drip tray, and heat baffle. Scrape and clean all grease from the drip tray, barrel, and grease channel. Ensure the grease drain and bucket are clear.
• Step 3 – Inspect RTD probe: Clean heavy soot from the RTD temperature probe. Replace the RTD temperature probe if it is bent, cracked, or heavily corroded.
• Step 4 – Check auger control: During a test run on low temperature, observe pellet feed. If the auger runs continuously even when temperature is above setpoint, the main control board may have a stuck relay and should be replaced.
• Step 5 – Avoid high-grease cooks without cleaning: After repair, clean more frequently when cooking fatty meats to prevent recurrence.
