Is the power cord plugged firmly into the bottom of the unit?
I don’t believe there is a fuse on this unit, but if there is it will normally be on the back of the controller.
Check the plug and the extension cord and they have power. Changed the plug location and extension cord and the grill still won't turn on. There is no red light on this model, there is only a white ring around the power button and that does not even come on.
Is there a fuse on the timberline's?
This is exactly what happened to me, too. Despite my years with electronics and electrical supply systems. I took apart the panel, reset all the connections, etc. This dummy (me) with no common sense didn't just reach down and re-seat the power cord. Worked 100% after that. HOWEVER... I can see why Traeger designed it that way (like a PC or monitor cord), but to have it underneath the unit and seated vertically, you're asking for a potential short. To me it should be hardwired like any countertop appliance. Gravity, movement and temperature fluctuations will unseat the female cord end from the male end in the bottom of the unit. I fear an arcing-type short could take place. I, for one, and at all risk to myself, am going to put a nylon yoke around the female end of the power cord and use nylon, heat-resistant threaded next nuts to secure the cord to the receptacle.
