An apparatus for extinguishing a stovetop fire including a microwave positioned above the stove top, a compartment defined in the microwave; and a closure retained in a closed position on the microwave. A projection member is positioned within the compartment, the projection member retained in a retracted position while the closure is in the closed position. A supply of fire suppressant material is retained within the compartment when the closure is in the closed position, the supply of fire suppressant material including a second burner portion positioned against the projection member. A heat responsive actuator is disposed on the microwave. When the microwave is positioned over a first burner on the stovetop, and the fire actuates the heat responsive actuator, the closure moves to an open position and the projection member moves to an extended position, the projection member forcing the second burner portion toward a second burner.
