Masterbuilt Charcoal Grill Err 2 — What It Means & How to Fix It
Err 2 on a Masterbuilt Gravity Series 600 means a meat probe has malfunctioned, and the manual sends you to Masterbuilt Customer Service.
What this code means
The troubleshooting table pairs Err 2 with "Meat probe malfunction". Unlike the other codes it lists no steps for the owner at all — the action column simply gives Masterbuilt Customer Service and its support page.
Masterbuilt's manual for the Gravity Series 600 (model MB20041023) lists "Err 2" in its troubleshooting table with this meaning. Masterbuilt's other grills and smokers have their own tables, so check the manual for your model number.

Frequently asked questions
Can I still cook with Err 2 on my Masterbuilt?

Is Err 2 the same as Err 5?
