Key Features

Set-and-Forget Precision with ACS

The Advanced Control System with Wi-Fi and Bluetooth Connectivity makes hands-free grilling a reality with the YS640s. Not only can you set the grill to a specific temperature from 150°F to 600°F in 5°F increments, but you can also make adjustments from your phone via the FireBoard app. At the core of the ACS control board is a powerful microprocessor that understands multiple input variables, allowing it to constantly learn and improve to adjust to varying cooking loads and conditions. 

• Advanced Control System with Wi-Fi and Bluetooth Connectivity
• Two integrated food probes for a complete picture of your cook
• Probe port on hopper side for convenience

American-Made Durability

Made from construction-grade materials in America’s heartland, Yoder Smokers are an investment meant to last a lifetime. You won’t find any wobbly wheels or flimsy walls here. With a 10-gauge steel cooking chamberand quality welding, the 335-pound YS640s is built to maintain consistent temperatures and retain heat even in the harshest elements. This results in less pellet waste than other grills and more consistent results.

Even the smallest details are accounted for, such as ball-bearing fans that provide better cold-weather performance than competitors, and a 14-gauge steel hopper and cart that are far more sturdy than lightweight aluminum grills. And even though rock-solid stability is a key feature of the YS640s, its heavy-duty casters make patio or tailgating moves surprisingly easy.

2-Piece Heat Diffuser

Adding versatility without the hassle of complexity, the 2-Piece Heat Diffuser makes it easy to transition from low-and-slow cooking to direct over-the-fire searing by simply removing the access door. This seamless mode switching allows you to amoke, flame broil, grill, bake, roast, and even griddle food all with one unit. 

The access door also makes emptying the burn grate between cooks a quick and easy process, as the diffuser plate can remain in place during the cleaning process. 

Dual Food Probes & Probe Port

No more babysitting your smoker, as the Fireboard app for Android and iOS allows you to remotely monitor dual food probes on the YS640s. You can also preprogram alerts and temperature adjustments after a specific period of time or when your food reaches a predetermined internal temperature. And probe life is extended thanks to a probe port on the hopper side of the grill that provides direct access to the cooking chamber without probe wires getting crimped underneath a closed lid.

10-Hour Hopper Run & 20-lb Capacity

This workhorse of a grill boasts tremendous stamina thanks in part to a high-capacity pellet hopper. Not only can it hold a 20lb bag of pellets, but the solid steel welded construction maximizes pellet efficiency. Enjoy up to 10 hours of precise, hands-free grilling as the YS640s chugs dutifully along while you work, sleep, or play. 

Hands-Free Performance & Versatility

We mean it when we say “hands-free” grilling with no babysitting involved. There’s no need to open the lid for temperature checks, which speeds up cooking and frees you up for other activities. You can confidently trust that the YS640s is completing the task at hand, but for added peace of mind, you can always check in via the Fireboard app to ensure your cook is proceeding as planned. 

Shipping and Assembly

Flat-rate shipping via freight for the YS640s is available for $100, or you are welcome to pick it up at our Wichita, KS, store location. Shipped orders are sent in 3-5 business days with the cart unassembled in a box to reduce freight damage, but the chamber comes pre-assembled. Two people are typically able to construct the cart in just 60 to 90 minutes using a handful of standard tools.

Quick Start Tips and Best Practices

Firing up your Yoder YS640s is both quick and easy. Once the pellet hopper is loaded and the grill is powered up, simply press the start button. You’ll immediately hear the auger move pellets into the burn pot for approximately 30 seconds, after which the igniter will power on to start the combustion process.

Many problems associated with failed ignition are prevented by the fact that the Yoder Smokers ignition system lights the pellets with induction heat. The ceramic ignition system outlasts conventional contact igniters by five times, heats up twice as quickly, and generates 100% more heat. 

Within 3 to 4 minutes, visible flames will appear. The fans and auger will work in concert to ensure the fire is fueled enough to help the grill reach the target temperature. For best results:

• Clean the burn pot of any ash or debris before each use.
• Consider placing a small handful of pellets (approximately ⅛ cup) in the burn pot prior to turning on the smoker. 
• Adjust the variable displacement damper to its widest position by pulling it fully to the right side of the Yoder YS640s. 
• Start your grill 20 to 30 minutes prior to cooking to allow the grill and cooking grates to heat thoroughly. This will improve heat retention and recovery when opening the cooking chamber door.
