What functions does the replacement controller provide?

The board restores core smoker controls including timing, settable grill temperature, and meat probe target temperatures. For larger models it also supports a Boost mode to quickly raise the grill temperature; note Boost is not available on the 560 model.

• Timer and grill temperature set controls
• Meat probe temperature selection for precise doneness
• Boost mode for rapid heat-up on 800 and 1050 models
• Four probe ports to monitor up to four cuts simultaneously

How weather-resistant and durable is the power adapter?

The kit includes an IP44-rated, splash-proof power cord designed to continue operating in rain or damp conditions around the grill area. While not fully submersible, this level of protection reduces moisture-related failures and keeps the controller powered during typical outdoor use.

• IP44 splash-proof rating for outdoor resilience
• Cord and adapter tailored for typical backyard weather exposure
• Designed for reliable daily grill operations in damp conditions

How do I troubleshoot errors or reset the controller?

If the display shows an error or the controller behaves unexpectedly, perform a simple power reset first. Disconnect the smoker from power, wait a few minutes, then reconnect; many transient issues clear with a full power cycle.

• Turn off the smoker and unplug the power cord
• Wait several minutes to allow internal capacitors to discharge
• Plug back in and power on to check if the error is resolved

Who is this replacement kit for? This Banbitebq control board and splash-proof adapter suit owners of compatible Masterbuilt Gravity Series grills who want a direct, wired replacement without WiFi or Bluetooth. It’s for grillers who need reliable probe monitoring, straightforward temperature and timer controls, and better resistance to outdoor moisture. If you require wireless connectivity, consider an alternative solution; otherwise this kit provides a practical, OEM-compatible swap to get your smoker back to work.
