WHIRLPOOL RANGE WFG505M0B Smells Like Gas

Oven Gas Safety Valve

This valve controls the flow of gas to the bake and broil burners. Internal diaphragm failure or weak solenoid seals allow a minute but detectable amount of gas to seep through the manifold even when the range is not in use, creating a persistent odor.

Oven Igniter (Bake)

As igniters age, their resistance increases, causing them to glow but not reach the high amperage required to open the safety valve quickly. This results in 'delayed ignition,' where gas is released into the oven cavity for several seconds before combustion, resulting in a strong gas smell during the start of a cycle.

Gas Pressure Regulator

The regulator stabilizes incoming gas pressure. If the internal vent or diaphragm is compromised, gas can escape directly into the air behind the range. This is the primary suspect if the smell is concentrated at the rear of the appliance rather than inside the oven cavity.
