When you think you’re cooking an excellent steak, an error code appears on your Traeger Grill; it can be a disappointing experience. 

This blog post will explain the meaning of the Traeger error codes and how to fix them.

Traeger LEr Code

The LEr code stands for “Low Error Reading on Traeger grills.” If you see this notification, your grill has been turned off because the temperature has been below 125 degrees for more than 10 minutes.

The following are possible causes of the LEr error on a Traeger grill.

  1. Firepot is too full or empty.
  2. Too much ash in the firepot
  3. RTD temperature sensor issue
  4. Cold ambient temperature or windy weather
  5. Chimney height
  6. Induction fan problem
  7. Poor pellet quality
  8. P-Setting adjustment

How to Fix Traeger LEr Code

If you set it for low and slow smoke, run out of pellets, and the firepot is too dirty and filled, the LEr Code may occur. Perhaps it’s a windy day, and your grill cannot reach the required temperature. In this case, raise the temperature setting.

However, if the weather is fine, you can perform the following checks.

Check the Firepot

  1. Turn off and unplug the grill, then wait for it to cool before proceeding.
  2. Begin by removing the bottom and upper grill grates, the drip tray, and the heat baffle. The firepot is located in the center of your grill underneath the heat baffle.
  3. If you see a buildup of pellets or sawdust on the sides, you need to clean it.

If the firepot is full of pellets, the fire probably went out during your cook. It could happen once in a while and isn’t a big deal until regularly.

Please try to resolve the problem by following the instructions below.

  1. Remove any excess pellets or ash from your firepot.
  2. Make sure you’re using high-quality wood pellets that are shiny but not crumbling.
  3. Before you begin, double-check that you’ve followed the correct startup procedure.

Check the RTD Temperature Sensor

If you’ve cleaned out your firepot but still have the LEr code, it’s time to check your grill’s RTD temperature sensor. It’s on the inside of your grill.

The sensor is used to keep track of the temperature within your grill. When it’s working, it helps keep the temperature stable.

Look inside the grill to see if it’s bent or touching anything.

Test your RTD to determine if it accurately measures the ambient grill temperature if it is bent, chipped, or appears to be broken.

There should be no problem if it correctly reads the ambient grill temperature, and you can continue grilling.

Check the Chimney

Ensure the cap on your grill’s chimney is at the proper height.

  1. Check the chimney for soot and buildup to ensure it’s not blocked.
  2. If necessary, clean the chimney.
  3. Between the chimney and the cap, you should be able to fit your thumb.

Check the Induction Fan

You should hear this fan when you start your grill. You can try spinning the fan with your hand to get rid of any dirt. You can replace the fan if it keeps making no sound and does not work.

Check the Weather

If it’s too cold outside, your grill may not be able to maintain the proper temperature.

Use an Insulation Blanket in this situation to maintain proper temperatures.

Check P-Settings

On some older grills, the P-Setting (Pause setting) is used to help monitor the grill’s temperature when temperatures are extremely cold or hot. If the ambient temperature is low, try lowering the P-Setting to a lower number.

Traeger HEr Code

A HEr code stands for “High Error Reading.” It usually occurs when the grill reaches over 550 degrees and shuts down.

The following are some possible causes:

Excessive Ash and Grease

It’s essential to clean and maintain your grill correctly, and too much ash and grease can make your grill challenging to read the accurate temperature.

Additional Pellets

If you did not shut down your grill properly after your previous cook, additional pellets might be in the firepot, causing the temperature to rise.

RTD Temperature Sensor

Check your RTD temperature sensor to see if it is bent, chipped, or appears to be broken. There should be no problems if it is correctly reading the ambient grill temperature.

Traeger Err or Er1 Code

If you get an Err or Er1 error, the RTD probe and the control panel are not connected properly.

Follow these steps to check the RTD connection:

  1. Turn off the grill and remove the screws that hold the controller.
  2. Remove the flathead screws that hold the RTD wires in the green box.
  3. Entirely remove the RTD wires from the green housing box. There is no need to remove the screws entirely.
  4. Make sure to tighten the flathead brackets to connect the RTD wires. It makes no difference in which direction or order the wires are connected.
  5. Place the controller back where it was, and screw in the two Phillips head screws you took out before. Plug the grill back in and turn it on to see if the code is still there.
  6. Please contact Traeger customer service if the Err or Er1 codes still appear on the controller.

Traeger Er2 Code

An Er2 error code means that the RTD probe (temperature sensor) has failed. Please contact Traeger customer service.
