Most likely causes (in order)
- ERR (general error) — Controller shows ERR – usually a failed igniter or RTD probe.
- LEr (Low Error / temp too low) — Grill temperature dropped below setpoint by more than 100F. Usually fuel or airflow.
- HEr (High Error / temp too high) — Temperature exceeded safe range. Usually flare-up or grease fire.
- Controller display blank or frozen — No display, unresponsive buttons. Usually a power issue or controller failure.
- WiFire connection lost — App shows offline. Usually WiFi range or router issue, not the grill.
ERR code fix
General error – usually triggered by igniter failure or RTD probe failure. Check both.
- Power cycle the grill (unplug 30 seconds).
- Restart and watch the igniter for orange glow within 60 seconds.
- If no glow, replace the hot rod igniter.
- If igniter works, check RTD probe for correct readings against a second thermometer.
Replacement parts and tools that fix this:
- Traeger Hot Rod Igniter Replacement — Fix ERR from failed igniter.
- Traeger RTD Temperature Probe Replacement — Fix ERR from failed RTD.
LEr (Low Error) fix
Grill temp fell too low. Usually pellets ran out, auger jammed, or airflow blocked.
- Check hopper is not empty.
- Verify pellets are dry and flowing.
- Clean the firepot and grease tray if soot buildup.
- Restart and monitor.
Replacement parts and tools that fix this:
- Traeger Pellet Storage Bucket with Gamma Seal Lid — Prevents wet-pellet issues.
- Traeger Drip Tray Liner 5-Pack — Easier cleanup of grease tray.
HEr (High Error) fix
Temp exceeded safe range – grease fire or flare-up. This is serious – shut down and inspect.
- Immediately close the lid to smother the fire.
- Shut off the grill and unplug.
- Once cool, clean out all accumulated grease from the drip tray and grease bucket.
- Inspect the firepot for damage before restarting.
Replacement parts and tools that fix this:
- Grill Armor Heat Resistant Gloves 932F — Handle hot components safely.
- Traeger Grease Bucket Liner 5-Pack — Prevents grease bucket overflow.
Blank display / frozen controller
Power problem or controller board failure. Check power first.
- Verify outlet has power (test with another device).
- Check power cord for damage.
- Power cycle 60 seconds.
- If still blank, controller board may be failed.
Replacement parts and tools that fix this:
- Traeger Controller Board Replacement — Replacement controller.
- CyberPower CP1500PFCLCD UPS Battery Backup — Protects controller from power surges.
WiFire connection lost
Grill is fine – WiFi signal is not reaching it. Fix the WiFi, not the grill.
- Verify the grill is within range of your WiFi router.
- Check for interference or dead zones.
- Consider a WiFi extender or mesh node near the grill.
- Verify router firmware is up to date.
Replacement parts and tools that fix this:
- TP-Link Deco XE75 Wi-Fi 6E Mesh 3-Pack — Extends WiFi to outdoor grill area.
