P5
Display shows P5 and grill runs hotter than expected in smoke mode with less visible smoke.
Smoke / P‑Setting Too High (Short Off Time Between Auger Cycles)
Symptom
Auger does not turn; no pellets feed into fire pot even though grill is on and calling for heat.
Auger Motor Not Running
Symptom
Auger makes loud grinding or squealing noises during operation.
Auger Bearing Wear / Pellet Dust Contamination
Symptom
Combustion fan runs loudly, rattles, or vibrates excessively.
Combustion Fan Imbalance or Bearing Wear
Symptom
Excessive ash blowing around inside the cook chamber and onto food.
High Airflow/Ash Carryover.
Symptom
Grease dripping from front or sides of grill instead of into grease bucket.
Grease Management System Blocked or Misaligned
Symptom
Grease fire in cook chamber; large flames under food.
Grease Ignition / Fire Pot Flare‑Up
Symptom
Grill leaks heavy smoke from around the lid, hopper lid, or seams.
Smoke Leakage / Poor Sealing
Symptom
Grill powers on, but will not ignite; pellets feed into fire pot but never light.
Hot Rod Igniter Failure
Symptom
Grill produces very little smoke even at low temperatures.
Low Smoke Production
Symptom
Grill starts but then shuts down mid‑cook; display goes blank.
Intermittent Power Loss
Symptom
Grill struggles to reach set temperature and stays 50–100°F below target.
Low Temperature / Insufficient Heat Output
Symptom
Grill temperature is much higher than the setpoint; food cooks too fast and may burn.
Runaway Temperature / Overheating
Symptom
Grill temperature swings widely (±50–75°F) during a cook.
Unstable Temperature Control
Symptom
Grill will not power on; no lights or display when plugged in.
No AC Power to Control Board
Symptom
Pellets in the hopper swell, crumble, or form clumps; the auger jams frequently.
Moisture‑Contaminated Pellets.
Symptom
Rust forming on grates, drip tray, or inside cook chamber.
Corrosion of Steel Components
Symptom
Strong chemical or plastic smell during first use or after storage.
Burn‑Off of Manufacturing Oils or Contaminants
Symptom
The display is very dim or unreadable, but the grill still heats.
Display Backlight or LCD Failure.
Symptom
The display shows temperature, but buttons do not respond or respond intermittently.
Keypad/Button Contact Failure.
Symptom
The frame or legs feel unstable; the grill rocks or wobbles when touched.
Cabinet/Cart Instability.
Symptom
The grease bucket overflows or fills very quickly during normal cooking.
Excessive Grease Drainage.
Symptom
The grill shuts off when a GFCI outlet is used, but it runs on a non‑GFCI outlet.
Ground Fault/Leakage Current.
Symptom
The hopper lid or main lid does not close properly; visible gaps remain.
Lid Misalignment or Warping.
Symptom
The lid thermometer (if equipped) shows a different temperature than the digital display.
Temperature Reading Discrepancy.
Symptom
Water or rain found inside the pellet hopper; pellets are swollen and stuck.
Hopper Water Intrusion.
