Jenn-air Cooktop Symptoms — Complete Troubleshooting Guide

Three Jenn-Air cooktop symptoms across the gas and radiant tops on the Whirlpool W10 and W11 platform. A gas burner that clicks without lighting is worked by reseating the brass burner cap, clearing carbon off the electrode, and then checking the spark module and the igniter well. A single dead radiant zone is usually a burned-out element or the infinite switch for that zone. Lopsided flames are a cap not sitting flat or ports clogged on the weak side.

Which zone fails is the diagnostic here. One dead radiant element while the others work points at that zone's element or switch rather than the board; one lopsided gas burner while the rest are even points at that burner's cap and ports rather than the supply. The guides use that comparison deliberately, because it turns a cooktop into its own control group and eliminates most of the expensive suspects for free.

Carbon on an electrode and a misseated brass cap are homeowner work — lift, clean, dry and reseat. Radiant elements, infinite switches and control-board relays sit on the mains side under a glass or metal top, and the igniter well is part of the gas assembly. Kill the breaker before any panel comes off, and book the repair when the fault is a zone element, a switch or the spark module.
