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.
