Possible Causes

Momentary loss of AC power, Loose power cord connection, Tripped breaker or GFCI, Internal control board brownout detection

How to Fix / Troubleshooting

Safety first: Ensure the grill is stable and cool before troubleshooting.

  • 1. Check household power:
    • Verify the outlet has steady power and the breaker/GFCI is not tripping repeatedly.
  • 2. Inspect power cord:
    • Ensure the cord is fully inserted into the outlet and grill.
    • Replace the cord if there are visible cuts or burns.
  • 3. Restart safely:
    • After a power failure, follow Masterbuilt's restart procedure: remove excess pellets from the fire pot, ensure no unburned fuel overload, then restart on SMOKE/LOW.
  • 4. If PF recurs frequently:
    • Try a different outlet or circuit.
    • If only the grill is affected, the control board may be overly sensitive and require replacement.
