Lid Sensor Error - Timberlines & Ironwoods

What's in This Article?

What to do when Error: 0023 Lid Sensor Error comes up on your new Timberline or Ironwood grill. 




During a cook, the lid sensor reports that the lid is open, and the controller does not see a drop in temperature.



The grill continues to cook but at a reduced performance.



  1. Make sure FIRMWARE is up to date.
    1. If the error number displayed is the old number, update the firmware. 

  2. Close the lid and confirm the magnet is working. 
    1. Simply close the lid to verify if the light turns off, followed by opening the lid to verify if the light turns on.
      • If the light turns on, there is no problem, and no replacement is needed. 
      • If the message continues, proceed to the next step.
  3. Ensure the grill is cool and finished with its shutdown cycle.
  4. Run a SELF-TEST to ensure there are no disconnects. Follow the steps below:
    1. On the controller display, go to MENU > MAINTENANCE & CARE > SELF-TEST. The test should take about 10 seconds to complete. 
    2. If the SELF-TEST fails, proceed to the next step.

IMPORTANT: Before proceeding

To continue you'll need to remove your hopper service panel. To remove this panel for the first time, you'll need to use an impact driver to remove the screws behind the P.A.L rail on your hopper service panel. 

  1. If this is your first time removing the hopper service panel and you don't have an impact driver of your own. Contact our customer support team and we'll send you a complimentary manual impact driver.
    • If you already have a manual impact driver, proceed to removing the hopper service panel.
    • If you have already removed the service panel screws, you can disregard the impact driver and use a regular Phillips screwdriver.
  2. Once you've removed the screws using the impact driver, continue with the next steps outlined here in this article.

Once you've verified current firmware and have the hopper service panel removed:

  1. Turn off and unplug your grill.
  2. Confirm all connectors are fully connected manually.
    1. Remove the smart combustion cover.
    2. Confirm connections on the motherboard are secure.
      • If you are unsure, disconnect and reconnect all connections.
    3. Confirm the cable connection to the lid sensor are intact and secure.
    4. Confirm wiring is not pinched, cut, or damaged inside the hopper.
    5. If any cabling is damaged, contact Customer Support.
    6. Turn on your grill to see if the issue resolved.

 Ensure there are no leaks/damage in the seal around the grill seal (gasket) or lid that may be causing a dip in temperature that would allow the cause of the error to occur.

Rerun a Self-Test to ensure all connections are secured from checking manually.
