Yoder Smokers YS Series Pellet Grill Thermocouple Replacement, Back Wall

Yoder Smokers YS Series Pellet Grill Thermocouple Replacement – Back Wall Frequently Asked Questions

What does this thermocouple replacement fit?

This longer “back wall” thermocouple fits Yoder Smokers YS480 and YS640 pellet grills built **before January 27, 2015**. It also works with YS1500 models that **do not** have the ACS (Wi-Fi) controller. It’s not compatible with newer models that use side-wall sensor systems.

Why isn't this compatible with grills that have ACS (Wi-Fi) controllers?

Grills with ACS controllers use a different short thermocouple design mounted on the **side wall**, and are available in either Type J or PT-1000 versions. This longer back-wall unit does not work with those systems.

How can I confirm which thermocouple my grill needs?

First, check your grill’s build date or whether it has ACS (Wi-Fi) capability. For newer ACS models, use the “About” menu to view your firmware or probe type—this will tell you whether the grill uses a Type J or PT-1000 short thermocouple.

How do I install the back-wall thermocouple?

Installation involves removing two screws and nuts from the back-wall bracket, pulling the old thermocouple out, and sliding the new unit into place. Reuse the existing bracket hardware to secure it—Yoder provides step-by-step instructions in the replacement guide.

Is this product made in the USA?

Yes—this part is manufactured in the USA, ensuring quality and compatibility with Yoder's heavy-duty pellet grills.
