Code	Meaning	Severity
AUGER-NOT-TURNING	The auger is a metal screw inside a tube that rotates continuously to push pellets from the hopper into the firepot. When it stops turning, either something's physically blocking that rotation, the motor driving it has died, or the shear pin connecting the two has snapped. No auger movement means no fuel to the fire. moderate	moderate
Er1	Er1 means the controller tried to read the RTD probe circuit and got nothing back. Either the circuit's open (broken wire or bad connection) or the probe element itself failed and resistance went way out of range. The controller won't operate without a valid temp reading. moderate	moderate
Er40	Er40 fires when the Traeger controller runs its startup sequence, the fan spins, pellets drop into the firepot, but the grill doesn't hit the minimum temperature threshold (around 125°F) within the startup window. The firepot didn't ignite. That's the whole story. moderate	moderate
FLAMEOUT	Wind, Pellets, Fan, and Firepot Solutions moderate	moderate
HEr	HEr on a Traeger means High Temperature Error. The RTD probe inside the barrel reported a reading that's 125°F or more above your setpoint, so the controller killed power to the fan and auger as a safety measure. Basically the grill said 'this is way too hot, I'm shutting down.' high	high
HUB	Complete reference for all Traeger pellet grill error codes. WiFIRE and D2 controllers display alphanumeric codes when something's wrong: LEr for low temperature errors, HEr for dangerously high temps, Er1/Er2 for sensor faults, and Er40 when the firepot fails to ignite within the startup window. moderate	moderate
LEr	LEr on a Traeger pellet grill means Low Temperature Error - the grill temperature dropped more than 125F below the set temperature for over 10 minutes. The controller shut down the grill to prevent unburned pellets from accumulating in the firepot. moderate	moderate
LOW-TEMP	The Low Temp Error fires when your grill drops more than 25 degrees below your set point and can't recover within a few minutes. Traeger's controller is basically saying the fire went out or is about to, so it's killing the auger feed to stop raw pellets from piling up in a cold firepot. moderate	moderate
NOT-HEATING	Something in the ignition-to-airflow chain is broken. Either pellets aren't lighting because of a dead igniter, bad airflow, or wet pellets, the fire's getting smothered by ash buildup, or the controller thinks it's already hot because the RTD probe is reading wrong and cuts back the pellet feed. moderate	moderate
NOT-SMOKING	When your Traeger fires up, the hot rod ignites pellets in the firepot while the induction fan controls airflow. At low temps the fire smolders and produces visible smoke. Crank it above 300F and combustion gets too efficient, burning pellets so completely that smoke becomes nearly invisible. No visible smoke doesn't mean no smoke flavor. moderate	moderate
TEMP-SWINGS	Temperature swings happen when the controller's feedback loop breaks down. The RTD probe sends a resistance reading that the controller uses to adjust pellet feed rate. If that reading is off because the probe is coated in residue or failing electrically, the controller over-corrects, dumps too many pellets, causes a spike, then backs off too hard and causes a drop. It just keeps chasing itself. moderate	moderate
