Temperature Sensor (RTD) Fault
Symptom
Control panel buttons unresponsive or intermittent; cannot change temperature or mode reliably.
Keypad / Control Panel Input Failure
Symptom
Digital temperature display fluctuates wildly (e.g., jumps 50–100°F) without actual temperature change.
Erratic Temperature Reading / Electrical Noise
Symptom
Display is very dim or segments missing, but grill otherwise operates.
Display Module Degradation
Symptom
Excessive vibration or rattling of grill body during operation.
Structural Vibration / Loose Panels
Symptom
Grease fire in cook chamber; flames from drip tray or below grates during cook.
Grease Ignition / Drip Tray Fire
Symptom
Grease leaking from bottom of grill cabinet instead of into grease bucket.
Grease Drainage Failure
Symptom
Grill overshoots set temperature by 50°F or more and struggles to stabilize, especially at low settings.
Temperature Overshoot / Poor Temperature Regulation
Symptom
Grill powers on but will not ignite; pellets feed into firepot but never light, requiring manual lighting.
Weak or Failed Hot Rod Igniter
Symptom
Grill produces excessive white smoke and sooty residue on food; pellets smolder instead of burning cleanly.
Incomplete Combustion / Poor Air-Fuel Mix
Symptom
Grill starts but then goes out mid-cook; fire dies and temperature drops to ambient while controller continues running.
Fire Extinguishing / Flame-Out During Operation
Symptom
Grill struggles to reach or maintain high temperatures (e.g., cannot exceed 350°F) even with lid closed.
Low Maximum Temperature / Insufficient Heat Output
Symptom
Grilla Grills pellet grill will not power on at all; no lights or display.
No Power / Dead Control Board
Symptom
High-pitched squeal or rattling noise from fan area during cook.
Combustion Fan Bearing Wear or Obstruction
Symptom
Loud grinding or squealing noise from hopper area during operation.
Auger Mechanical Noise / Bearing Wear
Symptom
Meat probe temperature reading is inaccurate or does not change during cook.
Faulty Meat Probe or Probe Jack
Symptom
Paint bubbling or peeling on exterior near firebox or exhaust.
High-Heat Paint Failure
Symptom
Pellets backing up into firepot and overflowing, causing large piles of unburned pellets.
Overfeeding / Poor Combustion
Symptom
Pellets not feeding at all from hopper to firepot, but auger motor can be heard running.
Auger Shear Pin Failure or Coupling Slip
Symptom
Rust forming inside cook chamber or on grates despite normal use.
Corrosion of Interior Surfaces
Symptom
Strong smoke smell or smoke leaking heavily from hopper lid during operation.
Backdraft Through Hopper / Poor Exhaust Flow
Symptom
Water intrusion into hopper or cook chamber after rain, causing pellets to swell and jam.
Moisture Ingress / Hopper Water Leak
Symptom
WiFi or app connectivity issues with Grilla Grills controller (if equipped); cannot connect or maintain connection.
Wireless Communication Failure
