Description
xWMJNH replacement kit for Masterbuilt Gravity Series grills provides a high-temperature fan, durable wiring, and three hopper lid/door switches to restore airflow and safety controls.
This complete repair set is built to bring aging or damaged components back to reliable operation in Masterbuilt Gravity Series 560, 800 and 1050 models. Instead of buying a full new unit, this kit supplies the key electrical and mechanical parts—fan, wiring harness and hopper lid/door switches—engineered to match OEM fit and withstand the heat of pellet-grill use.
How will this kit improve my grill’s temperature control?
The upgraded fan and wiring help maintain more consistent combustion by delivering steady airflow and reliable power transfer. Improved wind force from the high-temperature plastic fan promotes more complete pellet burn and a steadier internal temperature.
- Fan designed to replace part 9904190040 for stronger, more stable airflow
- High-temp plastic construction resists heat distortion during long cooks
- Wiring harness replaces 9904190045 with heat-resistant conductors for reliable connectivity
- Better combustion means reduced temperature swings during cooking
What’s included and how does each component match my Masterbuilt model?
The package contains one fan kit, one set of electrical wires and three hopper lid/door switches. These parts are compatible with a range of Masterbuilt Gravity Series model numbers and are intended as direct-fit replacements for the listed OEM items.
- Fan kit replaces OEM 9904190040 to restore forced-air performance
- Electric wire kit replaces OEM 9904190045 with easy plug-and-play connections
- Three hopper lid/door switches replace OEM 9904190041, rated AC 250V, 2A

How difficult is installation and what should I expect?
Installation is straightforward for basic DIYers familiar with small appliance wiring and grill disassembly. The components install in the same locations as the original parts and use the same mounting points and connectors.
- Direct-fit pieces minimize modification or fabrication
- Wiring uses standard connectors for simple swap-out replacement
- Switches are high-temperature rated and mount where the hopper lid engages
- Manufacturer support offered if you encounter issues after purchase
Who is this for? This WMJNH kit suits owners of Masterbuilt Gravity Series 560, 800 or 1050 grills who need to replace a failing fan, frayed wiring, or worn hopper lid/door switches without the expense of a new grill. It’s ideal for home grillers comfortable with basic electrical swaps or professional technicians performing routine repairs. If you need dependable, heat-resistant replacement parts to restore consistent airflow, accurate temperature response and safe lid-switch operation, this kit provides the core components in one package.
