Overview 

This article explains how to identify the type of the Thermocouple.

Instructions

1. Locate your temperature probe(s).
2. Follow the probe cable from the tip of the probe to where it ends - most likely the backside of the roaster's temperature display or inside of the control tower.
3. The color-coded ends of the thermocouple wires refer to the thermocouple type, as shown in the graph below.

Examples

The following examples show common Thermocouple types. Please note that the specific sensors on your roaster may vary by model and manufacturer.
