Low Error Reading (LEr)

Low Error Reading (LEr)

Applies to: All AC platform Grills except 2017 AC Timberline 850/1300

Brief Description: You may get this error message if the temperature in your grill dropped below 125 degrees for more than 10 minutes and caused the grill to shut off.

Common Causes:

  • Firepot empty (or only ash) or too full
  • RTD temperature sensor issue
  • Cold ambient temperature
  • Chimney height
  • Induction fan problem
  • Windy weather
  • Poor pellet quality
  • P-Setting adjustment


  1. Unplug the grill and wait for it to cool before proceeding
  2. Remove the grill grates, drip tray, and heat baffle and check the Firepot
  3. If the Firepot is completely empty or only has ash inside, it means the grill ran out of pellets at some point
    1. Even if you refilled the hopper before the fire went out, there may be a space in the auger where there are no pellets, causing the fire to go out
    2. On small cavity AC grills (Junior, Tailgater, Bronson) there could be void tunneling in the hopper where pellets are not able to make it into the auger even if there are pellets in the hopper.
      1. See the article on Tunneling vs Running out of pellets for more information
    3. Clean the Firepot and restart your grill
    4. See the Grill Startup Guide to find the proper startup procedure for your grill
  4. If the Firepot is full of pellets, it usually means that the fire went out during your cook
    1. This may happen occasionally and isn't a major concern unless it happens frequently
    2. Please follow the steps below to try and resolve the issue
    3. Ensure you follow the proper startup for your grill
      1. See the Grill Startup Guide to find the proper startup procedure for your grill
      2. An improper startup can affect a cook, even hours in
    4. Verify that you are using good quality pellets (shiny, not crumbling)
      1. If the pellets seem dull or crumble easily, try using a fresh bag of pellets
      2. See Pellet Guide for more information on pellet quality
    5. Clean out your Firepot of any excess pellets and/or ash
  5. Verify that your RTD temperature sensor isn't damaged
    1. Check to see if it is bent or touching anything inside the grill
  6. Ensure your grill/RTD is reading the ambient temperature accurately
    1. Compare the temperature on your controller when you first turn it on to the temperature outside
    2. The two temperatures should be within +/- 10F degrees of each other
  7. Check your chimney
    1. If your grill has a chimney, make sure that the cap is at the right height
    2. You should be able to fit a thumb between the chimney and the cap
    3. Check the chimney to ensure it isn't blocked with soot and buildup
      1. Clean the chimney as needed
  8. Check the induction fan on your grill
    1. You should be able to hear this fan when starting your grill
      1. If there is no sound, it sounds weak or is making squeaking noises, try to manually spin the fan to break up any grime
      2. If the fan still seems to be weak, please contact Customer Service @ 1-800-TRAEGER
  9. Cold weather makes a difference
    1. If the weather is too cold, your grill may have issues reaching and holding the proper temperature
    2. In this case, use an insulation blanket to maintain proper temperatures
      1. Note: Insulation blankets are not for use on all grills
      2. See the article on Insulation blankets for more information
  10. Windy conditions
    1. Gusty and/or consistent strong winds can make it difficult for all grills, but especially small grills, to maintain temperatures
    2. In windy weather try to locate the grill in a spot where it is shielded from the wind.
  11. P-Settings (Pause setting)
    1. The P-setting (Pause setting) is used on some older grills and is used to help monitor the temperature of the grill when experiencing extreme cold or hot temperatures.
      1. The idea of a P-Setting is simple: when it is extremely cold outside and the grill is running at a low temperature, the lower the P-Setting. The lower the P-setting, the more often the auger is spinning. This is to prevent the flame from going out.
      2. This idea is the same for when temperatures outside are high and the grill is running at a higher temperature. The P-setting can be set high to maintain temperature as well.
      3. The P-setting can also be used if the grill is running too hot or too cold. We can adjust this setting to help maintain the temperature.
    2. Grills with adjustable P-settings may require slight adjustments in select combinations of temperature settings and ambient conditions
    3. Low temperature and Smoke settings in cold and/or windy conditions may be more consistent if P-settings are set to P-0 or P-1 to provide more fuel.
    4. See the P-Setting article for more info.
