Kenmore Gas Stove Smells Like Gas — What to Check

Treat a strong smell as an emergency#

Natural gas carries an added mercaptan odorant precisely so you notice it, and a real leak is both a health hazard and an explosion risk. If the odor is strong, do not flip light switches or use a phone indoors, and do not strike a match or lighter. Turn the shutoff valve so its handle sits perpendicular to the pipe, open doors and windows, get everyone out, and call the utility from outside. Only troubleshoot once the smell is faint and clearly tied to one spot.

Know which maker built your Kenmore#

Kenmore gas ranges are not built by Sears — they are manufactured by Whirlpool, LG, or Electrolux depending on the model, and the first three digits of the model number tell you which: 110 is Whirlpool, 796 is LG, and 253 is Electrolux. That matters because the replacement valve or igniter your range needs is the parent brand's part, not a generic one.

Where a Kenmore range usually leaks#

• Loose flex connector (most common). The corrugated gas line behind the range works loose over time, especially after the stove has been pulled out to clean behind it. Brush soapy water over both ends and every union and watch for growing bubbles. Never seal a flare fitting with pipe tape.
• A burner that isn't fully lit. A knob a hair off the off position, or a ring lit on only one side, lets raw gas escape from the dark ports. Confirm every knob is fully off and clear any clogged ports.
• A valve that won't close. On older Kenmore units a worn surface-burner valve seat weeps a faint, constant odor near the knobs even with everything off; that valve is replaced, not cleaned.
• A cracked burner tube or orifice. Corrosion — worse in coastal, salty air — can split a tube so gas escapes before the burner head.
• The oven safety valve. If the smell comes from the oven with everything off, the safety valve may be seeping and needs replacing.

Confirm it safely#

Mix dish soap with water, brush it on the flex connector, its unions, and the manifold fittings, and look for bubbles. Then light each burner one at a time: the flame should be mostly blue with small yellow tips. Heavy yellow or lifting flames point to a fouled port or air-shutter issue rather than a supply leak. With all burners and the oven off, sniff around the oven vent and the base — an odor there points to a valve.

Before the holiday season#

Ranges get pulled out for a deep clean right before the holidays, and that is exactly when a flex connector gets nudged loose. After you slide your Kenmore back into place, run a two-minute soapy-water check on the connection before the first big roast. If the smell persists after you have checked the connectors and burners, don't keep guessing — book a visit and have the valves leak-tested by a licensed technician.
