A gas oven that does not light is experiencing one of three difficulties: no burner ignition, no gas to the burner or a combination of both. Simple observations narrows down the issue to a solvable problem.
An operational gas oven lights within a few seconds of the ignition being pressed. The ignition clicks as sparks are released at a rate of 3 to 5 sparks per second. When these sparks come into contact with the gas that is released into the burner, the burner lights up. A lack of ignition to the oven burners results in a clicking sound without the strong blue spark; there may be no spark or a pale white spark.
A homeowner can inspect the wiring for corrosion, breaks, pinching or cleaner build up. Correct any issues and try to light the burners again. If the clicking is slow or erratic, this means the outlet is not calibrated correctly. A professional needs to be consulted to fix the issue. If a steady blue spark is present when the igniter is initiated but the burner does not catch flame, the homeowner has to turn off the gas line to the appliance and refrain from using it until it is repaired by a professional.
