Troubleshooting a Thermocouple

What's in This Article?

Is your thermocouple not working? The steps below will help you determine if your sensor is no longer working correctly. If you have a new Timberline or Ironwood, follow these troubleshooting steps.

To accurately check a thermocouple, your grill must be turned off, cooled down, and out of direct sunlight. 

  1. On WiFIRE grills, ensure the thermocouple is not covered by a protective cap.
    1. If the protective covering was plastic and is melted, contact Customer Support.
    2. If the protective covering was paper/cardboard and it did not burn off during seasoning, remove it. Keeping the covering on will cause temperature issues.
  2. Check for Damage.
    1. Verify that the thermocouple temperature sensor is not bent or chipped.
      • A broken, bent or chipped thermocouple may still work as designed. Continue additional validation steps.
    2. Is the thermocouple touching another part of the grill?
      1. If so, gently bend the thermocouple away from the wall or object it is touching and continue troubleshooting.
  3. Check the Ambient Air Temperature.
    1. Turn on the grill and ignite to any temperature.
    2. Take note of the initial temperature displayed on the controller, indicating the starting point of heating, and then compare it with the outside temperature.
      • A working thermocouple should read within 20°F/10°C of the ambient air temperature. If it is reading the ambient grill temperature correctly, there is no problem, and you can continue grilling.
      • If your grill is reading more than 20°F/10°C off the local temperature, contact Customer Support to find out if you need a Thermocouple replacement.

If you have any questions, please contact Customer Support
