What to do if your Traeger grill enters shut down mode after removing a wired meat probe from the grill's controller.
The grill shuts down on its own after unplugging a wired meat probe.
Your Traeger grill has safety precautions set up in its programming to protect itself from events like power surges. In this situation, you were likely carrying static electricity on your person (i.e. walking on carpet with socks), when you unplugged your meat probe. The grill recognized a power surge and entered shut down mode as a safety precaution.
What to Do
This is a normal function, and your grill will continue to work as designed in future cooks. To prevent this from happening again, you can ground yourself by touching a part of the grill (like the hopper lid) before plugging in or unplugging your wired meat probe.
