Controller Board Power/Logic Failure
FAN
Display shows a fan-related error or WiFIRE app reports “Fan Error”; grill struggles to ignite or maintain flame.
Induction Fan Failure / Airflow Fault
FIRMWARE
Controller displays a firmware error or becomes stuck on an update screen; grill may not start.
Controller Firmware Corruption
HEr
Display shows “HEr” (High Error) and grill shuts down during cook.
High Temperature Shutdown / Overheat Protection
IGN
Display or app shows “Ignition Error” or “Igniter Error”; grill fails to light and times out.
Igniter / Hot Rod Failure
LEr
Display shows “LEr” (Low Error) and grill shuts down or fails to reach set temperature.
Low Temperature Shutdown / Flame-Out
NO PELLET
Display shows “NO PELLET” or similar low pellet warning and grill shuts down or won’t ignite.
Pellet Level / Feed Interruption
SENSOR
Display shows a generic “SENSOR” or “TEMP SENSOR” error; grill will not regulate temperature.
Temperature Sensor / RTD Fault
WiFIRE
Controller or app shows WiFIRE connection error; grill cooks but cannot connect to Wi-Fi or app.
WiFIRE Connectivity / Communication Fault
Symptom
A strong chemical or plastic smell during first use or after replacing parts.
Burn-In Odor / Off-Gassing
Symptom
Controller buttons or dial are unresponsive or intermittent.
User Interface / Keypad Failure
Symptom
Excessive vibration or shaking of the 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 the cook chamber; large flames, very high temperatures, and heavy smoke.
Grease Ignition / Fire Event
Symptom
Grease is leaking from the front or sides of the grill instead of into the grease bucket.
Grease Drainage / Channel Blockage
Symptom
Grill overshoots the 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 the firepot and the fan runs, but no flame develops.
Ignition Failure / No Flame
Symptom
Grill starts but then shuts down mid-cook; the temperature drops and the fire goes out.
Flame-Out During Operation
Symptom
Grill struggles to reach the set temperature; it remains 50–100°F below target even with the 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 the switch is turned ON.
No Power / Dead Controller
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 the exterior or near the firepot area.
Heat Damage to Finish
Symptom
Rust forming inside the cook chamber or on the grates.
Corrosion / Finish Degradation
Symptom
Smoke or flames are coming out of the hopper; pellets in the hopper are smoldering.
Backburn / Fire in Hopper
Symptom
The auger is jammed; a loud grinding noise or motor hums but pellets do not move.
Auger Jam / Pellet Compaction
Symptom
The auger is not turning; no pellets feed into the firepot even though the grill is on and calling for heat.
Auger Motor Not Running
Symptom
The grill produces excessive white smoke and sooty residue on food.
Incomplete Combustion / Rich Burn
Symptom
The grill produces very little smoke, even at low settings; food lacks smoke flavor.
Lean Burn / High Combustion Efficiency
Symptom
The hot rod igniter glows, but pellets still fail to ignite or take a very long time to light.
Weak Ignition / Poor Pellet Contact
Symptom
The induction fan is not running; no airflow into the firepot, resulting in a weak or no flame.
Induction Fan Not Operating
Symptom
Unusual grinding, squealing, or rattling noise from the hopper area during operation.
Mechanical Noise from Auger or Fan
