Description

Perfect fit for Masterbuilt Gravity Series: WiFi controller designed as a replacement for Masterbuilt Gravity Series 560/800/1050 models MB20041220, MB20041320, MB20040220, MB20041020, MB20040221 and MB20040122, replacing original part numbers 9904190036, 9904200043 and 9904200004.

Upgrade to full app control: Adds Bluetooth and WiFi connectivity so you can pair the grill with the Control app, adjust settings remotely and monitor temperatures in real time from your smartphone.

Intuitive control panel: Designed for effortless operation, the front panel features a large, bright LED display readable in direct sunlight. A tactile Rotary Knob allows for quick temperature adjustments and menu navigation. Dedicated buttons let you instantly toggle power, set timers, and switch between Fahrenheit and Celsius with a simple press-and-hold combination.

Smart timer & Boost functions: Take control of your cook time with dual timer modes: a Countdown Timer for precise recipe tracking and a Count-Up Timer to track total cook duration. For Model 800/1050 owners, the exclusive "Boost Mode" button accelerates fan speed (adjustable levels 0-8) to reach searing temperatures faster than ever.

Advanced diagostics & Status Icons: The panel provides instant visual feedback on your grill's health. Clear LED icons indicate the status of the Fan, Ignition, and WiFi connection. If an issue arises (e.g., disconnected probe, voltage error, or overheating), the screen displays specific Error Codes (Err 1-6), helping you troubleshoot instantly without guessing.

Quad-probe capacity for precision cooking: The panel supports up to 4 meat probes simultaneously (Ports MP1-MP4). You can set individual target temperatures for each probe directly on the panel or via the App. An audible alarm triggers once your meat hits the target, ensuring perfect results for brisket, ribs, and pork shoulder every time.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $31 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Grilleviathan products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
