Self Test & Part Diagnosis

Here you will find instructions on running a part diagnosis scan and self test on new Timberline and Ironwood grills. 

Self Test vs Part Diagnosis

	SELF TEST	PART DIAGNOSIS
When to run	Run before Part Diagnosis Run any time you get an error or a part of the grill is not responding as expected.	Run after Self Test
What does the scan check?	Checks if parts controlled by the motherboard are responding and connected. Checks if the flame sensor senses light Checks if the lid sensor senses the lid magnet	Checks if parts controlled by the motherboard are triggering an error.
Scan Results	The display will show a list of connected parts with either a green check (√) check or a red exclamation mark (!). The green check indicates the part is connected and responding to the motherboard.  The red exclamation mark indicates the part is not connected or is failing.	If a part is triggering an error, the error will show on the screen along with a QR Code that takes you to the associated error troubleshooting article. NOTE: If a part is malfunctioning but an error code does not exist for the failure, nothing will show up in the diagnosis.
What it looks like

Self Test

What does Self Test do? Self Test checks if parts controlled by the motherboard are responding and connected.

Does the grill ignite when running Self Test? No. The grill does not engage any components when running Self Test. It simply checks if the components are connected and responding to the motherboard.

Does the grill need to be cooled down to run Self Test? Run Self Test when the grill is cool for the following reasons.

• Safety: For Self Test to check the flame sensor, you will need to remove the grill's internal components so you can shine a light onto the flame sensor, which should only be done once the grill is a safe temperature to do so.
• Consistent Variables: Waiting to run Self Test until the grill is cool will allow any smoke that could be potentially blocking the flame sensor to clear.

How to Run Self Test

The Self Test function on your grill is accessed by MENU > Maintenance & Care > Self Test. Follow these detailed instructions to have the most successful Self Test.

1. Power on your grill. 
   • If your grill is already on, power cycle your grill by turning it off > unplugging the grill > pressing the power button on and then off > plugging in the grill > turning it on.
2. Insert both Wired Meat Probes. 
   
   • If not plugged in, the Wired Probe checks will fail (this is fine; just keep in mind).
3. Remove the grates, drip tray, and heat shield and firepot.
4. Vacuum out the barrel, including in the firepot cavity.
5. Place a flashlight/cell phone light into the firepot cavity and shine it toward the Flame Sensor (toward the auger). This will mimic the light normally produced by the fire.
6. On the controller display, press the MENU button to display the menu carousel.
7. Turn the dial until you reach MAINTENANCE & CARE and press the dial to confirm your selection. Then select, SELF TEST. 
8. Let the grill run the complete SELF TEST, leaving the grill undisturbed while this completes. It should take about 15 seconds or less to complete. 
9. When SELF TEST completes, the screen will show a list of parts with either a ✓ or an ! (see image below).
   • A check (✓) indicates the part is connected and responding to the motherboard.
   • An ! indicates the part is either not connected or not responding to the motherboard. 
   • Lid Sensor Fails: Because the lid is open so you can hold a light into the firepot, the lid sensor can't find the lid magnet, and it will fail the Self Test.
10. Repeat steps 6-8 with the lid closed to check the lid sensor.
    • This time the flame sensor will fail since you are not shining a light into the firepot.  
11. All parts pass: Great! Your grill's components are responding to the grill's motherboard.
    • Replace all internal parts: firepot, heat shield, drip tray and grates.
12. All parts don't pass: Continue to run PART DIAGNOSIS, following the steps below, to determine if the failing parts are triggering an error. 
    
    

How to Run Part Diagnosis

What does Part Diagnosis do? Part Diagnosis checks which, if any, components are triggering an error.

Always run a SELF TEST prior to running PART DIAGNOSIS.

1. On the grill controller display, press the MENU button.
2. Turn the dial until you reach MAINTENANCE & CARE and press the dial to select.
3. Select PART DIAGNOSIS.
4. This scan is very quick.
   
   • If an error populates: An ! icon will appear next to the part throwing an error. Select, More Info to diagnose further.
     
   • If no errors populates: you will see this screen below saying, "All good under the hood."
     
5. Complete any troubleshooting based on the error produces.
6. Once you complete additional troubleshooting, run another SELF TEST to ensure all the parts have been reconnected successfully and are communicating as expected.
