What is an AC Wire Harness?

An AC wire harness delivers AC power to the power supply board when triggered by the power button.

Take the steps below to remove and replace an AC Wire Harness.

Ensure grill is off and unplugged.
Remove the hopper side service panel by removing 6 screws (2 located on top of the access panel, 2 below the hopper side rail, and 2 on the bottom of the access panel).

Before removing the hopper service panel: check your grill’s manufacturer date.

June 2023 (2306) or after: Proceed to remove service panel.
Before June 2023 (2305): Remove the access panel using an impact driver to prevent the possibility of stripped screws. If you don't have one on-hand, contact Traeger Support.
