Err1 = Temperature probe “open” / not connected
• Err1 is displayed on the controller
• Alarm will sound continuously
• Fan stops
• No other functions work except POWER
• What to do:
• Check to make sure your temperature sensor plug is properly connected to the controller.
• Remove the temperature sensor plug from the controller, wipe the plug with a clean rag, reconnect the plug.
• Unplug the controller from the power supply, wait 10 seconds, reconnect.
• Check the temperature sensor wire. Check if there are any bends / kinks / breaks / frays in the wire.
• If you cannot get Err1 to clear from the controller, likely, the user needs a new temperature sensor. Look for
“Temp Probe Kit” in NetSuite.
Err2 = Meat probe malfunction / failure
• Err2 is displayed on the controller
• No alarm will sound
• Fan still works
• Grill operation is normal
• What to do:
• Check to make sure the meat probe is plugged in correctly.
• Unplug the controller from the power supply, wait 10 seconds, reconnect.
• Check the meat probe wire. Check if there are any bends / kinks / breaks / frays in the wire.
• Plug the meat probe into a different jack on the controller. If the new jack removes the Err2, the original jack is not
functioning correctly, the user needs a new controller. Look for “Controller Assembly Kit” in NetSuite.
• If you cannot get Err2 to clear from the controller by trying all the jacks on the controller, likely, the user needs a
new meat probe. Look for “Meat Probe” in NetSuite.
• If the user does not have a meat probe installed, user likely needs to update their firmware.
