Gas Smell From the Stove or Oven

If your kitchen smells like rotten eggs or sulfur, shut off every burner, open a window, and call your gas utility if the smell is strong. Natural gas is odorized to smell that way on purpose, so a sulfur smell gets treated as gas until someone confirms otherwise. Maybe you notice it when the oven lights, maybe it's there all day. Below is the order to do things in, what to leave alone, and who to call first.

Do These Things First, In This Order

1. Stop and sniff. If the smell is strong, skip to step 5. 2. Turn every burner knob to off, and check that no knob is parked between settings. 3. Turn the oven off. If a pot boiled over onto a burner, what you smell may be gas that never ignited. 4. Open a window or two and the back door so air moves through. 5. If the smell is strong, sharp, or making you lightheaded, get everyone outside and call your gas utility from the yard. A faint smell that fades a minute after you shut the burners off is a different animal than one that keeps building. Trust the building smell.

What Not to Do

Don't flip light switches on or off. Don't unplug the range or hit a breaker in a room that smells like gas, because sparks are the whole problem. Leave the ceiling fan and the range hood fan alone too. No candles, no matches, and don't hold a lighter to a burner to see if it lights. Don't go sniffing along the gas line behind the range, and don't pull the range away from the wall. That flex connector back there is not something to tug on. Don't lift the bottom oven panel or pop off burner caps to poke around. And don't wait it out hoping it fades. Air the room out and get an answer.

When to Leave the House

Leave now if the smell is strong anywhere in the house and not just at the stove. Leave if you hear a hiss near the range or down in the basement. Leave if anyone has a headache, feels nauseated, or gets dizzy. If the smell is in the basement near the water heater or furnace, that's a different problem than a stove burner, and it's still a reason to walk out. Take the pets. Leave the door open behind you if you can manage it without touching a switch, then stand well away from the house. Call the gas utility from there. They come out for this and they don't charge you to check.

Utility First, Us Second

The gas company handles the line coming into your home, the meter, and the shutoff. They'll tell you whether gas is leaking and where it's coming from. If the leak turns out to be inside your range or oven, say a bad valve, a cracked igniter assembly, or a burner that won't light, they may shut gas off to that appliance and tag it. That's when you call us. We're an independent shop working on gas ranges and ovens from all major brands, including igniters, safety valves, burner assemblies, and thermocouples. Hang onto the tag, or write down what the utility tech told you. It saves us diagnostic time.

Smells That Aren't Actually Gas

A brand-new oven usually smells odd the first few times it heats up. That's oil burning off the metal. Run it empty at a moderate temperature with a window cracked and it goes away. Grease spilled under a burner turns sour when it heats, and so does a self-clean cycle. In an older Midwest kitchen, a musty basement draft can drift up through a floor gap near the gas line and smell strange without being gas at all. Still, natural gas is odorized to smell like rotten eggs. If that's what you're smelling, treat it as gas and call the utility. Guessing wrong costs too much.

Gas Smell From the Stove or Oven — what people ask

Can I still use my other burners if only one smells?

No. Shut the whole range down until someone confirms where the gas is coming from. One burner valve failing doesn't mean the rest are fine, and you don't want an open flame anywhere nearby while you figure it out.

Should I shut off the gas valve behind my stove myself?

Only if you can reach it easily without moving the range and the smell is mild. If you'd have to pull the appliance out or crawl in behind it, leave it be and let the utility handle the shutoff.

How long should I air out the kitchen?

Give it fifteen to twenty minutes with the windows open and the burners off. If the smell is gone and stays gone, it was probably unlit gas from a knob. If it comes back, stop using the range and call.

How it works

  1. Step 1

    Tell us the symptom

    Call us or fill out the form and describe what you hear, smell, or see. An error code helps. So does a puddle. We ask the brand and rough age so the van carries the parts we are likely to need.

  2. Step 2

    We come look

    Our technician tests the machine instead of guessing: water lines, heating elements, drain pumps, control boards. Then we explain what failed in plain words before any wrench turns.

  3. Step 3

    Repair and clean up

    Common parts ride with us, so a lot of repairs finish on that first visit. Special-order parts get scheduled right away. We run the cycle with you standing there, then haul off the old part and the packaging.

Why homeowners call us

  • Hard water is our specialtyMidwest water leaves scale on everything it touches. Crusted dishwasher spray arms. Clogged ice maker lines, and washers and water heaters full of mineral buildup. We know what that grit does to valves and seals, so we treat the cause instead of the symptom.
  • Basement laundry roomsBasement setups fail differently than upstairs ones, between the long drain runs, the cold concrete, and lint packed into a vent that runs through the rim joist. We check the venting and the drain path too, not only the machine, so the same problem does not come back.
  • Freeze-thaw season readyGarage freezers quit in January. Ice makers stop when the supply line freezes, and dryers labor when the vent hood ices over. Seasonal swings break appliances in fairly predictable ways, and those are the first things we look at on a winter call.
  • Independent, all major brandsWe are not tied to any manufacturer, so we work on whatever is sitting in your kitchen or laundry room: refrigerators, ranges, dishwashers, washers, dryers, freezers. One shop, one call, whatever badge is on the door.
  • All major brands, gas & electricIndependent service on Whirlpool, LG, Samsung, GE, Maytag, Bosch, KitchenAid and the rest.
  • Straight answersIf it isn't worth repairing, we'll say so, often right on the phone.
