Whirlpool 4322452 manual Testing a GAS Safety Valve

TESTING A GAS SAFETY VALVE

Some gas ranges use an electrically-controlled gas safety valve to control the flow of gas to the oven burner. The electric safety valve controls the gas flow by means of a bimetal-controlled diaphragm. Self-clean models have a single inlet, dual outlet, bimetal-operated safety valve. To prevent miswiring, the bake and broil terminals are sized differently. Several typical safety valves are shown in Figures 6-9 through 6-11. To test a gas safety valve:

1.Turn off the gas and electrical power to the range.

2.Set the ohmmeter to the R x 1 position.

3.Disconnect the wires from the bake and broil terminals.

4.Touch the meter leads to each set of terminals. The meter should indicate a low resistance reading of between 1Ω and 5Ω. If the meter indicates an open circuit, or a high resistance, replace the valve.
