If your Masterbuilt Gravity Series 1050 digital charcoal grill or smoker shows erratic temperature readings, unresponsive buttons, or Bluetooth/app connection issues, this COMVIEE controller provides a straightforward way to regain reliable physical control.

How will this replacement panel restore grill performance?

Replacing a faulty control board with the COMVIEE 9904200004 returns direct, local control of fan speed, temperature setpoints, and cook timing via the digital display and push buttons. The unit communicates with the grill fan and sensors to maintain the temperature you program, so your charcoal smoker behaves predictably again.

• Restores LED temperature and timer readouts for accurate monitoring.
• Controls the digital fan to hold set temperatures during cooking.
• Uses physical push-button inputs when app/Bluetooth is unreliable.
• Non‑WiFi design avoids connection instability and simplifies operation.

Is installation difficult and what tools are needed?

The panel is designed for direct replacement and typically installs with basic hand tools; you only need to remove the old board and reconnect the existing harnesses. The straightforward plug-and-play layout reduces time at the grill and minimizes wiring mistakes compared with more complex aftermarket controllers.

• Basic screwdriver set to remove housing screws and mount the panel.
• Reattach existing plug connectors—no soldering required in normal swaps.
• Follow component orientation and screw torque to avoid damage.
• Note: this package does not include an antenna since it has no Wi‑Fi.

Will I lose any original features by choosing this non‑WiFi board?

This replacement restores all physical control functions—temperature adjustment, fan control, and timer—matching the original hardware experience but without Wi‑Fi connectivity. If you routinely rely on smartphone control and remote monitoring, this unit focuses on stability and direct operation rather than app features.

• Maintains full local control via the digital display and buttons.
• Eliminates Wi‑Fi-related connectivity errors and Bluetooth instability.
• Ideal when consistent temperature control matters more than remote access.
