Why Those Errors Occur

Traeger error codes are one way that your Traeger grill can communicate to you that something is wrong. While they can be frustrating, these codes can also provide valuable information about what is happening with your grill. 

There are a few different things that can cause Traeger error codes, ranging from simple issues to complex sensor problems.

  • The most common reason is due to the Traeger RTD Probe issue. This is the temperature sensor that is located in the grill. It is possible for this probe to become dislodged or damaged, which will cause an error code. 
  • Another reason why an error code may occur is due to firepot issues. The firepot is where the pellets are burned. If there is a problem with the firepot, it can cause an error code. 
  • Finally, Traeger error codes may occur if the pellets are not burning efficiently. This can be due to a variety of reasons, such as wet pellets or a dirty grill. By troubleshooting the problem and following the instructions in your Traeger manual, you should be able to clear the error code and get your grill up and running again

LER Code Fixing On Traeger Grill

LER means “low-temperature error.” This Traeger error code occurs when the temperature is inside the grill drops below 125 degrees. There are a few different things that can cause this, such as:

  • The pallet inside the fire pot is missing causing the temperature to drop. check to ensure that the pellet is in the fire pot. If it is not, add more pellets to the grill.
  • The chimney’s height is too low. The Traeger Pellet grill needs a 12-inch clearance from the top of the chimney to the bottom of the grate.
  • Windy weather may also cause LER. If it is windy, try to position the Traeger grill so that the wind does not blow directly into it.
  • Traeger suggests checking the grill’s temperature sensor and comparing it with the temperature inside the grill. If they are not reading the same, Traeger recommends replacing the temperature sensor.
  • Remove the grill gate and clean the fire pot. Sometimes, ashes and debris can build up in the fire pot and cause the temperature to drop.

HER Code Fixing On Traeger Grill

HER stands for’ High Error Reading’.When the temperature inside the grill exceeds 550°F/ 287C°from the set point, HER errors occur. when this error occurs the grill automatically shuts down. This Traeger error code can be caused by:

  • Check if your chimney is clean there might be some blockage in the chimney. Check to make sure that the chimney is clear and there are no obstructions.
  • The Traeger grill is placed too close to a wall or other obstruction. Make sure that the Traeger grill has at least 24 inches of clearance on all sides.
  • If the internal parts are not installed properly, they might be causing the grill to overheat. Traeger recommends double-checking all of the internal parts to make sure they are installed properly.
  • A working RTD probe is essential for Traeger grills to function properly. Traeger recommends checking the RTD probe and replacing it if necessary.

  • Plug the grill back into the power supply and turn the grill power switch on. If there is still an issue ER1 will be displayed on the display.
  • There might be loose sensor wires Traeger recommends checking the connection and tightening it if necessary. The sensor wiring is located at the back of the Traeger grill.
