ERR
ER1
ER2
ER4

LEr Code On Traeger 

LEr stands for Low Error Reading. It is an error message specific to non-WiFIRE grills. Getting this message means that your grill dropped below 125°F for more than 10 minutes, causing your grill to shut off.

Fixing LEr Code on Your Traeger Grill

1. Power Down and Move the Grill
   • Turn off the Traeger grill and unplug it from the power source.
   • If it’s cold outside, relocate the grill to a sheltered area or a spot with full sunlight to reduce wind chill effects.
2. Inspect and Clean the Firepot
   • Remove the grill grates, drip tray, and heat baffle.
   • Check the firepot for any ash buildup and clean it out using a vacuum.
3. Restart the Grill
   • Reassemble the grill and follow the startup instructions for igniting the wood pellets, as outlined in the grill’s manual.
4. Check the RTD Probe
   • Inspect the RTD (Resistance Temperature Detector) probe for visible damage, such as bends, chips, or breaks. If damaged, replace it.
   • If the probe touches another part of the grill, gently reposition it away from contact.
   • Clean the RTD sensor with steel wool if it appears dirty.
5. Verify Temperature Readings
   • Turn on the grill and check the temperature displayed on the controller.
   • Compare this temperature to the outside air temperature. A functioning RTD probe should read within 20°F/10°C of the ambient temperature. Note that the grill will read higher if in direct sunlight.
6. Inspect the Chimney
   • Ensure the chimney cap is positioned about a thumb’s width from the chimney.
   • Check for any soot or buildup in the chimney and clean it if necessary.
7. Examine the Induction Fan
   • Listen to the fans’ sounds during startup. It should be audible.
   • If the fan is silent, weak, or making unusual noises, manually spin it to dislodge any grime. If it remains non-functional, replace the fan.
8. Adjust the P-Settings
   • Adjust the P-setting (Pause setting) to accommodate extreme temperatures. For cold weather, set it from P-4 to P-3 or P-2 to increase the frequency of wood pellet feeding into the auger.

HEr Code on Traeger

When your grill reaches over 550°F, usually due to a fire, it will automatically shut off, and the controller will display “HEr.” 

Common causes of the HEr error code include excessive ash or grease buildup in the grill, a defective temperature probe, a faulty temperature controller, and poor-quality pellets with excessive dust.

Fixing HEr Code on Your Traeger Grill

A HEr error code usually resolves after restarting your grill. To ensure optimal performance, check the firepot for dust, remove any pellets, ensure all parts are intact, and verify the RTD probe is accurate. Restart the grill and confirm it maintains a stable temperature of 225°F. If so, your grill is ready for use.

ERR & ERR1 Code On Traeger 

The causes for the Err/Er1 error code are usually a bad connection or a complete disconnect between the RTD probe and the control panel.

Fixing ERR & ER1 Code

To fix the Err/Er1 code, turn off and unplug your grill. Next, remove the two Phillips-head screws securing the controller. On the back of the controller, loosen the flathead brackets that hold the RTD wires in place. Disconnect the RTD wire from the green housing box, then reinsert the wire and tighten the brackets securely.

If the Err or Er1 codes still appear on the controller, you need to replace the temperature probe. 

ER2 Code On Traeger

A faulty RTD probe or control panel is the most common cause for the Er2 error code.

Fixing ER2 Code

• Inspect Wires: Check inside the grill for any breaks or tears in the wires leading to the RTD probe.
• Unplug and Access Controller: Unplug the grill and unscrew the controller to access the wires on its back.
• Verify Connections: Ensure the RTD probe wires are properly connected and tightened.
• Reassemble Controller: Screw the controller back into its original position.
• Test the Grill: Turn on the grill. If the ER2 code persists, replace the RTD sensor.
• Further Action: If the ER2 error continues after replacing the RTD sensor, the controller may need repair or replacement.

ER4 Code on Traeger

The ER4 code on a Traeger grill indicates a low pellet sensor error. This typically happens when the pellet hopper is empty or the sensor malfunctions.

Fixing ER4 Code on Traeger

To fix the ER4 code on your Traeger grill, ensure the pellet hopper is filled with wood pellets, as the error often indicates a low pellet level. If the hopper is full, inspect the low pellet sensor for any obstructions or damage and clean it if necessary. Additionally, make sure the sensor is properly connected and functioning.

After addressing these issues, restart your grill to see if the error is resolved. Regular maintenance and prompt attention to sensor issues can help prevent recurring problems.

By familiarizing yourself with common error messages and their solutions, you can quickly troubleshoot issues and ensure your grilling experience remains smooth and enjoyable.

Regular maintenance, timely repairs, and prompt attention to error codes will help you keep your Traeger grill in top shape, allowing you to focus on what matters most—delicious meals and great times with family and friends.
