The purpose of a grounding wire is to ground electricity for safety and is required in all electrical appliances.
Grounding helps protect you and your home from the dangers of damaged circuits or electrical overloads. When power surges happen, the excess electricity introduced to the system could leap out of the wiring. Without electrical grounding, this stray voltage could start a fire, damage appliances, or shock bystanders.
It is especially important to note that they MUST be secured to the grill body with good metal-to-metal contact. Additionally, with AC Auger Motors, they will need to be grounded directly to the grill body.
When looking at the different wiring on your grill, such as the auger motor, controller, or power cord, you may notice a few differently colored wires. The only colored wires that ground the grill will be either green or green and yellow.
The grounding wires should already be attached to a new grill. If for some reason they are not, please call Customer Service @ 1-800-TRAEGER to notify us of this error.
If you have received a replacement part and need to know how to reconnect the grounding wires for your grill, see below based on which grill you have.
Ideally, you will want to reconnect the grounding wires to match how they were upon grill purchase. If you do not know how they were initially attached, you will take the green grounding wire and connect it by screwing a bolt over the metal loop, securing it into the back of the auger motor (as seen in the pictures below). The other end of the grounding wire will need to be grounded to a metal contact. There must be metal to metal contact, or the wires will not be properly grounded, which can cause problems later on.
Preferably, you will want to reconnect the grounding wires to match how they were upon grill purchase. However, if you do not know how they were initially attached, you will need to do the following: One end of the green/yellow grounding wire will be attached to the main power switch harness. The other end will have a metal loop to thread the auger bushing/self-tapping screw to connect it to the auger bushing. It is important to ensure that the auger bushing screw is lined up with the auger bushing groove. If this is screwed in too tightly, it can hinder the auger from moving freely.
