GAS VALVE
A typical Whirlpool gas valve and its component breakdown is shown in Figure 3-2. The gas valves
are used to control the gas flow to the top burners. The gas valves are usually mounted to the top
of the manifold pipe with a screw and rubber washer. The gas valve housing contains a hollow gas
control seat. As the valve stem is rotated, the hole in the seat rotates to align with the hole in the
top of the valve housing (see Figure 3-3). Gas from the manifold then flows through the holes to
the orifice.
There are two types of gas valves used, depending on the model of the range. The first type of valve
goes from closed to completely open by manually rotating the valve stem from 0˚ to 90˚. The second
type of valve has a stem rotation of 220˚.
The 220˚ gas valve has a low flame adjustment screw that is located inside the shaft of the valve
stem (see Figure 3-4). To adjust the control, use a small screwdriver, and turn the control until the
desired flame is produced.
