If your Masterbuilt Gravity Series grill or smoker is struggling to maintain temperature, this plug-and-play COMVIEE replacement fan kit is built to match the original part’s fit and function.

How will this replacement fan affect the grill’s temperature control?

Replacing a failing fan with this COMVIEE unit restores the digital grill’s ability to move air from the hopper into the cooking chamber, which stabilizes the burn rate of the charcoal. Consistent airflow helps the grill maintain the temperature you set on the controller, reducing unexpected spikes or drops.

• Restores precise airflow for steady combustion.
• Reduces temperature fluctuation during long cooks.
• Works with the grill’s existing digital controller—no rewiring needed.

Yes. The kit is intended as a direct replacement: it includes the fan, a stainless-steel guard, and four mounting screws so you can install it with basic tools. The fan is plug-and-play with the Masterbuilt electrical connector, so most owners can complete the swap in a short amount of time.
