Below you will find an overview of an induction fan's different functionalities and why this is important when grilling with a wood-burning grill.
What Is an Induction Fan?
The induction fan is one of the two fans inside your Traeger grill. Its job is to keep air moving so the fire can burn steadily. By pushing hot air and hardwood smoke throughout the cook chamber—similar to how a convection oven works—it helps your grill heat evenly and gives your food that signature wood‑fired flavor.
Depending on your grill model, the induction fan may look different:
- AC (non‑WiFIRE) grills: White fan with an orange wire harness
- WiFIRE®‑enabled grills: Black fan assembly
Images below show examples of each style:
Normal Induction Fan Behavior
WiFIRE Enabled Grills
Induction fans in D2 grills are managed by the controller, which tells the fan when and how fast to run. It is normal for the grill fan to run intermittently and at different speeds--the controller consumes information from other components of the grill and will adjust fan behavior to meet the temperature expectations you set. For example, you may notice fan behavior changes when you ignite your grill, use SUPER SMOKE, or change the grill temperature. You may also notice it mid-cook if the flame is low or has gone out and the controller is trying to re-ignite the grill.
Non-WiFIRE Grills
Unlike D2 grills, induction fans in AC grills run consistently. If you find that your AC grill's fan is not running as such, contact Customer Support.
Touchscreen Grills
The main induction fan functions similarly to the fans in WiFIRE enabled grills, however, they run at varying speeds and do not run constantly. It is normal for this fan to run intermittently, as required, based on the needs to maintain the grill's temperature. This means this fan will vary in rpm based on temperature settings, cook mode (super smoke vs. normal), the rate of temperature change, etc.
This is different from the hopper auxiliary fan, which is much smaller and will run to cool down the internal components of the grill. The induction fan will oscillate depending on the internal grill temperature, whereas the hopper auxiliary fan will run consistently.
