These replacement thermocouples are designed for Yoder Smokers Pellet Grills built on or after 1/27/15. The Type J thermocouple is used for legacy and S-series grills built prior to Summer 2022. Please use the steps below to determine whether you need a Type J or PT-1000 thermocouple for your particular S-series grill.

There are two probe types used in S-Series pellet grills, the type of probe must be verified as they are not interchangeable. To verify the type of probe that your pellet grill was built with, please follow these steps on your pellet grill:

1. Press the menu button at the main screen.
2. Rotate the selector knob clockwise, highlight "About" and
   press the knob. Then rotate knob clockwise again until
   you see probe under "About".
3. Note the type of probe your grill is using: it will either list "PT1000" or "Type J"

(For models YS640/YS480/YS1500 built after Dec 2021)
