Our take on the Yoder Smokers YS640s Pellet Grill with ACS - 2 Piece Diffuser

The YS640s is Yoder Smokers' flagship pellet grill, built in the US with heavy-gauge steel and a custom-coded microprocessor controller. It offers over 1,000 square inches of cooking space and the ACS (Adaptive Control System) for set-and-forget temperature control. The 2-piece diffuser lets you run direct or indirect heat, so it smokes, bakes, roasts and grills. It suits serious backyard cooks and competition teams who want a heavy, long-lasting pit and are willing to pay for it. Against mainstream pellet grills it is heavier, holds temperature well and produces strong smoke at low settings, but it costs much more and weighs far more than most rivals.

About the Yoder Smokers YS640s Pellet Grill with ACS - 2 Piece Diffuser

The Yoder Smokers YS640s is a pellet grill that smokes, bakes, roasts and grills. It is the flagship of Yoder's S Series and is made in America's heartland. It has 640 square inches of main grate space (20" x 32"). The standard second shelf brings total cooking space to 1,070 square inches.

Its Adaptive Control System (ACS) connects over Bluetooth and home Wi-Fi to the YS Drive app for iOS and Android, with cloud connectivity powered by FireBoard. Through the app you can control grill temperature, monitor meat with the two included food probes, and change cooking programs. One program holds a set temperature once the meat reaches a chosen internal temperature. The microprocessor-based board reacts to changes in heat, such as opening the door, adding cold meat or switching wood type mid-cook.

The ceramic igniter lights the pellets with induction heat. It lasts five times longer than conventional contact igniters and heats up twice as fast. The grill also has a redesigned high-airflow burn grate and an insulated hopper. A variable displacement damper creates different heat zones on the main cooking grate. Heavy-duty casters make it easy to move.

Questions and answers

What does the 2-piece diffuser do?
It lets you run the grill with the diffuser in place for indirect heat, or remove a section for direct grilling over the firepot. That gives you both smoking and searing from one pit.
What is ACS on the YS640s?
ACS is Yoder's Adaptive Control System, a microprocessor controller that manages the auger and fan to hold your set temperature. It is the main upgrade over earlier YS640 models.
How much cooking space does it have?
Yoder lists over 1,000 square inches across the main grate and upper shelf. That is enough for several briskets or a large crowd.
Does it need electricity?
Yes. The controller, auger and fan run on a standard 120V outlet, so you need power at the cook site.
Can it sear steaks?
Yes. With the diffuser section removed, the firepot area gives direct heat for searing, though it is not as hot as a dedicated charcoal grill.
Is it made in the USA?
Yes. Yoder Smokers builds the YS640s in Kansas.
