WiFIRE Connectivity / Communication Fault
Symptom
Auger is jammed; loud grinding noise or motor hums but pellets do not move.
Auger Jam / Pellet Compaction
Symptom
Auger is not turning; no pellets feed into firepot even though the grill is on and calling for heat.
Auger Motor Not Running
Symptom
Controller buttons or dial are unresponsive or intermittent.
User Interface / Keypad Failure
Symptom
Excessive vibration or shaking of grill during operation.
Mechanical Vibration / Imbalance
Symptom
Grease bucket fills very quickly or overflows during normal cooking.
Excessive Grease Production / Drainage Imbalance
Symptom
Grease fire in cook chamber; large flames, very high temperatures, heavy smoke.
Grease Ignition / Fire Event
Symptom
Grease leaking from front or sides of grill instead of into grease bucket.
Grease Drainage / Channel Blockage
Symptom
Grill overshoots set temperature by 50°F or more and runs too hot.
Temperature Overshoot / Runaway Heat
Symptom
Grill powers on but will not ignite; pellets feed into firepot and fan runs, but no flame develops.
Ignition Failure / No Flame
Symptom
Grill produces excessive white smoke and sooty residue on food.
Incomplete Combustion / Rich Burn
Symptom
Grill produces very little smoke even at low settings; food lacks smoke flavor.
Lean Burn / High Combustion Efficiency
Symptom
Grill starts but then shuts down mid-cook; temperature drops and fire goes out.
Flame-Out During Operation
Symptom
Grill struggles to reach set temperature; stuck 50–100°F below target even with lid closed.
Low Temperature / Underheating
Symptom
Grill temperature swings widely (e.g., 50–75°F up and down) during a cook.
Temperature Fluctuation / Poor Regulation
Symptom
Grill will not power on at all; no lights or display when switch is turned ON.
No Power / Dead Controller
Symptom
Hot rod igniter glows but pellets still fail to ignite or take very long to light.
Weak Ignition / Poor Pellet Contact
Symptom
Induction fan is not running; no airflow into firepot, weak or no flame.
Induction Fan Not Operating
Symptom
Lid does not close properly or appears warped; heat and smoke escape from gaps.
Lid Misalignment / Warping
Symptom
Meat probe readings are inaccurate or jumpy compared to a known-good thermometer.
Meat Probe Sensor Fault
Symptom
Paint bubbling, peeling, or discoloration on exterior or near firepot area.
Heat Damage to Finish
Symptom
Rust forming inside cook chamber or on grates.
Corrosion / Finish Degradation
Symptom
Smoke or flames coming out of hopper; pellets in hopper smoldering.
Backburn / Fire in Hopper
Symptom
Strong chemical or plastic smell during first use or after replacing parts.
Burn-In Odor / Off-Gassing
Symptom
Unusual grinding, squealing, or rattling noise from hopper area during operation.
Mechanical Noise from Auger or Fan
