Traeger Pellet Grill Not Heating Up: Every Fix From Firepot to Igniter
Quick Answer
Traeger not heating up: check the firepot first. In 40% of cases, the firepot is full of ash that insulates the fire and blocks airflow. Vacuum out all ash, then check that the hopper has dry pellets and the auger is feeding them to the firepot. If the igniter rod glows orange during startup but pellets do not catch, the rod is working but pellets may be damp or the firepot needs clearing.
A Traeger not heating up is the single most common pellet grill complaint and has multiple possible causes that must be checked in order. The #1 cause (40% of cases) is a firepot full of ash - when ash fills the pot, the igniter cannot reach the pellets and the fire either never starts or goes out quickly. The #2 cause (20%) is a burned-out hot rod igniter - this element glows red to light the pellets, and after 2-4 years of use it burns out like a light bulb. You can check it by starting the grill and looking into the firepot after 3 minutes - if the rod is not glowing orange, it has failed ($20-35 replacement). The #3 cause (15%) is pellet supply: empty hopper, jammed auger, or damp pellets that will not ignite. The #4 cause (10%) is cold weather - below 35F, the grill loses heat faster than it can produce it, especially without an insulation blanket. Start diagnosis by cleaning the firepot with a shop vac - this alone fixes 40% of all 'not heating up' complaints.
What Does the NOT-HEATING Code Mean?
Traeger not heating up: clean the firepot (40% fix), check igniter glow (20%), check pellet supply (15%), use insulation blanket in cold weather (10%). Start with the firepot every time.
