Self-clean heats the oven far beyond any cooking temperature to burn spills down to ash. If there is enough grease on the oven floor, it can light instead. Whirlpool warns that heavy soil means more smoke, and GE's manual says an excessive amount of grease may ignite and cause smoke damage to your home.
It is tempting to run the cycle in the weeks before the holidays, when the oven is about to work hard and people are coming over. A fire like this often stays inside the locked oven and goes out on its own. The smoke does not stay put, though, least of all in a 1920s bungalow kitchen or a small condo with a hood that only recirculates.
In the moment
- Turn the oven off and leave the door shut. That is what GE and LG both tell owners to do. Fresh air can feed a burst of flame, and forcing the door can break the latch. Do not reach behind the range.
- Decide whether to leave. If flames or heavy smoke come from the oven vent, the door seal or behind the range, or the cabinets beside it feel hot, get everyone out and call 911 from outside. Seattle Fire's cooking safety sheet says the same for any fire that is large or has spread. If a carbon monoxide alarm sounds, get out and call 911.
- Smell gas? Leave. On a gas range, go outside, leave switches alone and call Puget Sound Energy at 1-888-225-5773 or 911 from a safe spot.
- Kill the power if the controls will not respond. Switch the range off at the panel if you can get there without crossing smoke.
- Clear the air. Open windows and run a bathroom fan. Leave the hood off if flames or heavy smoke came out of the oven vent, which on most ranges sits at the back of the cooktop. Whirlpool warns that fumes from the cycle can harm birds, so move them to another closed, well-ventilated room.
- Watch through the window until the flames are gone, with an extinguisher in reach for anything that catches outside the oven. Never spray into the cavity.
- In a condo or apartment, tell the building if an alarm sounded or smoke reached the hallway.
- Photograph everything before you wipe anything: the oven window, the cavity once it opens, the door, the cabinets, the ceiling and every room that smells.
Getting the door open
Self-clean doors stay locked until the oven cools. Whirlpool's help page puts that at about 200 degrees, and a hot oven takes a long time to get there. If it is cool and still locked, cut the power at the breaker for about a minute. GE gives a similar reset of 30 seconds without power and says never to force the latch. Stand to one side when it does open, because LG warns that hot air or steam may escape.
Read the damage before you clean
A cleaning job looks like grey or white ash and black flakes on the oven floor, some soot on the door glass and a smell mostly in the kitchen.
Not a cleaning job is anything on the list in "When the range should not be used again" below. Stop there. If you may file a claim, leave the range as it is until the adjuster has seen it.
Step by step: cleaning the cavity
Wait until the oven is cold. Wear nitrile gloves and an N95 respirator, and keep the windows open. You need a plastic scraper, paper towels, mild dish soap, a bucket and microfiber cloths.
- Cut the power at the panel, or unplug a gas range if you can reach the plug without moving it far. A gas range sits on a flexible line, so do not drag it.
- Take out the racks and anything left inside, including any foil. GE's manual says not to line the oven bottom with foil, and melted foil on the floor of the oven is a job for a technician.
- Lift out the loose residue. Scoop ash and flakes with damp paper towels instead of a vacuum or brush, so you are not throwing soot into the air.
- Wipe the cavity with a damp cloth. LG allows a damp cloth or a soap-filled steel wool pad for leftover ash. Use mild soap on anything sticky, rinse and dry.
- Leave the gasket alone. Whirlpool says not to clean, rub or move the door gasket. Keep water and cleaner out of the slots in the door frame, and away from elements, burner ports and wiring.
- Skip the oven cleaner. GE's manual rules out commercial oven cleaner and protective liners anywhere in or around the oven.
- Wash the racks by hand and check whether your manual lets them stay in for the cycle. Many do not.
- Clean the rest of the kitchen from the top down. Try a dry soot sponge first on walls and cabinets, then a mild degreaser on anything that smears. Kitchen fire cleanup: the first 72 hours has the order that works.
- Air the house for a few hours. If the furnace ran while the kitchen was smoky, change the filter before it runs again.
When the range should not be used again
Leave the breaker off, or the range unplugged, and have it inspected or replaced if you find any of these:
- Cracked, clouded or loose door glass, or a warped door
- A latch that will not release, or a door error that comes back after the reset
- A gasket that is burned, brittle or torn
- A broken or blistered element, melted wire or a smell of burning plastic
- Any smell of gas, or a burner that will not light normally
- Blistered enamel, or scorching on the range body, the wall or the cabinets beside it
- A tripped breaker, a dead oven or a scorched outlet. A dead oven may be a safety fuse or a damaged control. Call an appliance technician for the range, and an electrician for the outlet or panel.
Look up the model on the Consumer Product Safety Commission's recall site too, since ranges and wall ovens have been recalled over the years for fire hazards.
If none of those apply, restore power and run the oven empty at a low bake setting for about 15 minutes with the windows open, and stay in the room. Any burning-plastic smell, odd flame or error code means turning it off at the breaker and calling a technician.
Lower the odds next time
- Wipe first. GE says to wipe grease and food soil out before a cycle. LG says to wipe heavy spills off the oven floor, and Whirlpool says to clean before the oven gets heavily soiled.
- Empty it. Whirlpool says to take out racks, the broiler pan, cookware and foil, and to clear plastic off the cooktop and the storage drawer.
- Stay home and awake. Seattle Fire calls unattended cooking the leading cause of home fires in the city, and a cycle this hot deserves the same attention.
- Pick your day. Run it a week or two before you host, not the morning of.
Typical costs around Seattle
These are typical Puget Sound ranges, not quotes. Prices vary with the range and how far the smoke went.
- Cleaning supplies: usually $30 to $80.
- Appliance technician's visit: commonly $100 to $200.
- Door lock, fuse or control repair: commonly $150 to $500.
- New range: from about $700 for a basic model to several thousand for a pro-style unit, plus installation.
- Electrician for a scorched outlet: commonly $200 to $600.
- Professional smoke cleaning: from several hundred dollars for the kitchen to the low or mid thousands when residue reached the main floor.
Compare the total with your deductible before you decide whether to file; the insurance guide to the first 72 hours explains how a claim runs. Where the claim is covered, restoration is $0 upfront on covered claims - insurer billed directly - deductible applies.
When to call a professional
Call a restoration company when:
- Smoke reached other rooms, closets or the upper floor, or the smell is still strong after two or three days of airing out. Smoke odor removal explains why cleaning has to come first.
- Cabinets, the wall or the ceiling are scorched or discolored. See kitchen and small fire cleanup.
- Firefighters used water or an extinguisher was used. Dry chemical powder is corrosive, and water runs under cabinets and floors.
- The house was built before 1978. Do not sand or scrape paint that may contain lead, and do not scrub a textured ceiling that may contain asbestos.
- Someone in the household has asthma or a heart or lung condition and the smell is not going away.
