Grill Power Issues - AC Timberlines

What's in This Article?

Steps to take when the AC Timberline grills experience power issues. This information applies to both Timberline 850 & 1300.



What does it mean when the grill has power issues? Below are some of the common symptoms you may see.

  • The controller display is not turning on.
    • This includes a black, dark or blank screen, fading pixels or flickering.
  • Cracked or damaged screen
  • The controller is turned on, but the grill isn't igniting.


Power issues may be caused by many factors, which we explore in the troubleshooting below. Most often, causes include the following:

  • Tripped outlet
  • The outlet isn't working
  • Faulty extension cord
  • Wiring connections
  • A grill power component is shorting out the controller
  • A grill power component isn't delivering power from the outlet to the grill
  • Occasionally, a failing controller

What to do

1. Check Power Connections

  1. Confirm the grill is plugged in and the power switch is set to the ON position.
  2. Is the Grill Connected via an Extension Cord?
    • Occasionally extension cords fail. Try plugging the grill directly into the outlet. If the outlet is too far for the cord to reach, try plugging another device into the extension cord to confirm it is delivering power.
  3. Inspect the Power Cord
    1. Look for any signs of damage or kinks.
    2. Confirm the Internal Parts of the Power Cord Aren't Damaged.
      1. Access the internal portion of the power cord through the bottom of the hopper.
      2. Thoroughly inspect the internal parts of the power cord for damage, such as frayed wires from rodents, etc. 

2. Inspect if the GFI Or GFCI Outlet Tripped

  1. If plugged into a GFI or GFCI outlet (outlet with a small center button, commonly found in bathrooms or near water), did the outlet trip?
  2. If so, reset the outlet by pressing the center button.
  3. Turn the grill ON.
  4. Set the grill to SMOKE and let run for 5 minutes
  5. If the outlet trips again, continue troubleshooting.
    • If the center button does not pop out, the outlet did not trip, and the outlet is not the issue. This means one of the components is the issue.
  6. See if the outlet is the problem:
    1. Unplug the grill, plug another appliance (toaster, blow dryer, coffee maker) into the outlet, and turn it on.
      • The appliance must pull at least 300 watts for this test to work. Small appliances similar to those listed should work. A phone charger will not suffice.
    2. If the GFI outlet trips again, there is an issue with the outlet or the circuit box.
  7. If the outlet does not trip with another appliance, the grill is tripping the outlet. Proceed to the next step.

3. Make replacements if necessary

  1. Power off the grill
  2. Unplug the power cord.
  3. Unscrew the controller from the grill.
  4. Unplug all grill components on the controller except for the power cord.
  5. Replace the power cord if:
    • There is any visible damage.
    • There are any singe marks near the molex or ground wire.
  6. Once done, plug all the grill components back and screw the controller back onto the grill.
  7. Plug grill in and turn on the grill. Check to see if the power switch illuminates. If not, replace the power switch.
  8. If it does illuminate but the controller is not working, replace the controller. Contact Customer Support for assistance.
