Traeger not igniting

Good evening everyone! I’m trying to figure a issue out with my grill. Simply put it isn’t igniting. It’s feeding pellets, and starting to smoke but isn’t catching the pellets on fire to properly grill. Do I need to replace the igniter or whatever it’s called? I’ve cleaned the grill and vacuumed it out multiple times. Still no improvement. Please help if Anyone has had similar issue.
