A slow leak from a defective gas valve or connection can accumulate to explosive levels in enclosed spaces — such as the cabinet area behind a gas range or the utility closet around a gas dryer. The odorant (mercaptan) added to natural gas provides the characteristic rotten-egg smell as a warning, but this odor can fade in long-duration leaks or in poorly ventilated spaces.</p> <p>For [Sacramento](/sacramento/sacramento)-area homeowners, PG&E provides free gas leak detection and emergency response at 1-800-743-5000, available 24 hours a day. If you smell gas from your Sub-Zero cooktop, whether or not it is related to this recall, evacuate the home without operating light switches or electrical devices, and call PG&E from outside. Never attempt to locate or repair a gas connection yourself unless you hold a California C-36 plumbing license or C-20 HVAC license.</p> <h2>Frequently Asked Questions</h2> <h3>How do burner valve stem seals fail?</h3> <p>Burner valve stems rotate inside the valve body, sealed by O-rings or packing material. Over time, heat from the burner (radiating upward through the cooktop) degrades these seals. As the seal material hardens and cracks, gas can seep around the stem. The leak is often very slow — detectable by smell but not by sound. High-BTU burners (like Wolf professional burners at 20,000 BTU) generate more heat near the valve, accelerating seal degradation.</p> <hr> <p><strong>Worried about your cooktop?
