Jenn-air Gas-stove Symptoms — Complete Troubleshooting Guide

Five Jenn-Air gas range symptoms, all on a Whirlpool-built platform whose failure order is well established. Constant clicking — including with every knob off — is classically a spark switch stuck under one knob. A burner that will not light works through that same switch, then the module, then the electrode. Lopsided or yellow flames are clogged ports, a misseated sealed cap or the gas setup. A burner that stays lit with the knob off is a valve that is not sealing.

The switch under the knob is what makes this hub different from other sealed-burner ranges. Because the spark switches sit behind the knobs rather than in the burner well, a stuck one keeps the module firing regardless of how dry and clean the burners are — so if drying and cleaning changed nothing, the knob position is the next thing to work, not the electrode.

The gas-smell guide adds a check specific to these ranges: the downdraft path, along with the cap seating and the supply connections. A brief whiff at ignition is different from an odour that lingers with everything off. A burner that will not shut off means gas is still flowing — close the wall shutoff immediately. Cleaning and reseating are yours; valves, orifices and supply connections are licensed work.
