Flame Sensor Disconnected - Timberlines & Ironwoods

What to do when you get Error: 0031 Sensor Disconnected error on your new Timberline or Ironwood grill. 

SYMPTOM

The grill continues to cook but at a reduced performance.

CAUSE

The grill has detected that the flame sensor is not connected. This could be due to a bad connection to the flame sensor or a failed sensor.

RESOLUTION

1. Make sure your grill's firmware is up to date.
   • Check your grill's firmware in your grill settings in the app or on your controller by going to Menu > Settings > About Grill.

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 connections are fully connected to the motherboard.
   
   
   1. Remove the Smart Combustion cover.
   2. Disconnect and reconnect all connectors.
   3. Confirm wiring is not pinched, cut damaged inside the hopper.
      • If any wires are pinched or damaged, contact Customer Support so we can replace those wire harnesses.
3. Turn on your grill to see if the issue resolved.
4. If the error reappears, turn off the grill and remove the hot rod service panel.
   1. From underneath the grill on the right side, find the hot rod service panel.
   2. Remove the four screws securing the hot rod service panel in place. 
   3. Pull out the service panel. The flame sensor is the at the back, sitting above the hot rod wires.
      
   4. Follow the flame sensor wires and disconnect and reconnect the wiring connection. 
      
   5. Reattach the hot rod service panel.
5. Turn on the grill. If the Flame Sensor Disconnected error still remains, contact our Customer Support team and we'll get you set up with a new hot rod service panel.
