LEr - Low Error Reading

A Low Error Reading of LEr, is an error message you may see on an AC platform Grills (non-WiFIRE enabled) except the 2017 AC Timberline 850/1300. Getting this message means that your grill dropped below 125 degrees for more than 10 minutes and caused the grill to shut off.

Common Causes

  • Empty firepot
  • Only ash in the firepot
  • Firepot too full
  • RTD temperature sensor issue
  • Cold ambient temperature
  • Chimney height
  • Induction fan problem
  • Windy weather
  • Poor pellet quality
  • P-Setting adjustment

Resolution

  1. Turn off and 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 empty or only has ash inside, it means the grill ran out of pellets at some point.
    • It is possible that there was a section within the auger that had no pellets, causing the fire to go out when the auger reached that section.
      • On small cavity AC grills (Junior, Tailgater, Bronson), there could be tunneling in the hopper--pellets cannot make it into the auger even if there are pellets in the hopper.
      • Clean the Firepot and restart your grill.
      • See Grill Start-up 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.
    • This may happen occasionally and isn’t a major concern unless it happens frequently.
    • Please follow the steps below to try and resolve the issue.
      • Ensure you follow the proper startup procedure as an improper startup can affect your cook, even hours into the cook.
      • Verify that you are using good quality pellets (shiny, not crumbling)
      • Clean out your firepot of any excess pellets and/or ash.
  5. Verify that your RTD temperature sensor isn’t damaged.
    • Check to see if it is bent or touching anything inside the grill.
    • If your RTD or thermocouple is bent, chipped, or seemingly broken, test it to see if it accurately reads the ambient grill temperature.
    • If it is reading the ambient grill temperature correctly, there is no problem, and you can continue grilling.
  6. Ensure your grill/RTD is reading the ambient temperature accurately. Then, with the grill cooled down, complete the following:
    • Turn on your grill and take note of what temperature shows up on the controller.
    • Compare this to the outside temperature, either using a third-party thermometer or the current daily temperature.
      • Acceptable temperature variation is within 20°F/10°C.
      • Note the temperature variation may be larger when the grill is sitting in the sun.
    • If the readings are more than 20°F/10°C off, contact Customer Service.
  7. Check your chimney.
    • You should be able to fit a thumb between the chimney and the cap.
    • If your grill has a chimney, make sure that the cap is at the right height.
      1. 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.
    • You should be able to hear this fan when starting your grill.
    • If there is no sound or is making squeaking noises, try to manually spin the fan with your hand to break up any grime.
      • If the fan still makes no sound and does not work, please contact Customer Service.
  9. Cold weather makes a difference.
    • If the weather is too cold, your grill may have issues reaching and holding the proper temperature.
  10. Is it particularly windy? * Gusty and/or consistently strong winds can make it difficult for all grills, especially small grills, to maintain temperatures.
    1.  In windy weather, try to locate the grill in a spot shielded from the wind.
    
  11. P-Settings (Pause setting) * The P-Setting (Pause setting) is used on some older grills and is used to help monitor the grill's temperature when experiencing extreme cold or hot temperatures. * Try adjusting the P-Setting to a lower number if the ambient temperature is low.
