HunGrill Fan & Hopper Door Switch Kit for Masterbuilt Gravity 560/800/1050 XL — Plug-and-Play, Fan Guard

HunGrill's replacement fan and hopper door switch kit restores reliable airflow and safety switches for Masterbuilt Gravity Series 560/800/1050 XL digital charcoal grills and smokers.

If your Masterbuilt Gravity Series grill shows fan failures, inconsistent temperature control, or a hopper lid that won't register closed, this comprehensive HunGrill kit provides the parts needed to get the unit working like new. Designed as a direct-fit replacement for OEM parts 9904190040 (fan) and 9904190041 (door switches), the kit includes a digitally compatible fan, three hopper lid/door switches, a complete wiring set, mounting hardware, and a protective fan guard so you can replace the worn components without modifying the grill.

How does the HunGrill fan improve temperature stability?

The included high-performance fan is built from heat-resistant materials and interfaces with the grill's digital controller to maintain steady airflow from the hopper into the cook chamber. A consistent supply of air helps charcoal burn evenly and keeps temperatures closer to the set point.

• Digitally compatible replacement fan designed for Masterbuilt Gravity Series models
• High-temperature resistant construction for long-lasting operation
• Fan guard included to protect blades and improve airflow direction
• Plug-and-play wiring for quick swap without controller changes

What switches and wiring are included and why do they matter?

This kit supplies three hopper lid/door switches (part #9904190041) plus four purpose-specific wires so your grill recognizes when doors and lids are closed. Those switches are safety-critical: they ensure proper fan operation and prevent the controller from running when the hopper or ash doors are open.

• Three durable hopper lid/door switches engineered for heat and wear resistance
• Complete electric wire kit: lid switch, ash door, hopper switch, and fan wire
• Pre-cut lengths and connectors for direct installation—no splicing required
• Reduces diagnostic time by replacing common failure points at once

Is installation difficult and what hardware is supplied?

Installation is intended to be straightforward: the kit is plug-and-play and includes all required mounting hardware so you can swap parts with basic tools. Clear component grouping and factory-compatible connectors minimize time on the workbench.

• All necessary screws, brackets, and a fan guard supplied for immediate install
• Fan and switches match OEM mounting points for direct replacement
• Wiring harnesses designed to reach original connection points without modification
• Common hand tools only—no advanced electrical work required
