Mode, not a failure
23 codes
Nothing on the grill has failed; the controller is showing a state it was put in on purpose. A shutdown cycle keeps the fan running to burn off the last pellets before the grill goes quiet, a keep-warm setting holds the cook box low, a demo mode lights the display without feeding fuel, and a pairing screen waits for a phone to connect. No part is needed; the button sequence in the manual, or simply letting the cycle finish, returns it to normal.

- Pellet Grill Temperature Swings Far From the Set PointGrill Error Code on a Pellet Controller or Digital Panel
The grill tried to start its fire and the controller never saw it take. On a pellet grill that is usually a hot rod burned out after hundreds of cooks, or a firepot full of ash so the new pellets smother; on a gas grill with electronic ignition it is a spark module, an electrode cracked or set too far from the burner, or a battery gone flat. Emptying the ash once the grill is cold and fitting a fresh battery are fair first steps; the hot rod and the module are a visit.

Flame and gas flow
7 codes
The control lost its flame or never found enough gas to hold one. The common reasons are plain: a propane regulator that dropped into its low-flow safety mode because the tank valve was opened with a knob on, a tank running empty, wind across an open burner, or a flame sensor coated in grease. Knobs off, the tank closed and reopened slowly, then a relight usually settles the first; if you smell gas, walk away first, and the valve, the sensor and every fitting stay with a technician.

Temperature and probes
14 codes
A probe is sending the controller a reading it cannot trust, or no reading at all: the grill's own temperature sensor coated in smoke and grease, its lead pinched or melted, or a meat probe unplugged, wet or reading far outside what any cook box could reach. The grill then overshoots, stalls or shuts down to be safe. Wiping the sensor once the grill is cold and reseating the probe in its jack are reasonable steps; a sensor that still reads wrong is a visit.

Pellet feed and auger
6 codes
Pellets stopped reaching the firepot. Sometimes the hopper simply ran low and a pellet bridge formed over the auger; more often damp pellets swelled into a hard plug inside the auger tube, or the auger motor strains and stalls against it. Emptying the hopper of soft or crumbled pellets and refilling with dry ones is a fair first step; clearing a packed auger tube, a sheared pin or a motor that hums without turning is a visit.

The fire is not getting the air the controller expects. On a pellet grill the combustion fan under the hopper may be seized with grease and dust or wired loose, or the firepot's air holes may be packed with ash; on gas grills with an electric cooling fan behind the control panel, a stalled fan trips a warning before the knobs get hot. Clearing ash from a cold firepot is safe to do; a fan that will not spin is a visit.

Controller and display
7 codes
The controller itself reported trouble, or stopped answering: a display that flickers or shows segments missing, buttons that no longer respond after rain got behind the panel, a board whose relays stick, or an app that will not keep its connection. A full power cycle, done as the manual describes with the grill cold, clears a passing glitch; a code that returns, or any sign of water behind the display, means a board or a keypad, and that is a visit.

The grill is not getting clean power: a GFCI outlet on the patio that tripped in rain, an extension cord too long or too thin, a transformer for the lights or the rotisserie that failed, or a power supply inside a pellet grill that sags when the hot rod draws. Resetting the GFCI once with the outlet dry, and plugging straight into it, clears many. A trip that repeats, or a burning smell, means the grill stays unplugged until a technician has looked.
