My Range Ignitors Spark But Gas Doesn't Come On & the Oven Won't Light

Check the Gas

• The first thing to check in this situation is the gas. If gas isn't getting to the range, no amount of ignition spark will produce a flame. Double-check that the gas supply is turned on both at the wall and outside the house. Check the gas line connections between the range and the indoor gas supply by dripping mineral oil around the join while the gas is turned on -- if air bubbles appear, there is a leak, and you should immediately turn off the gas and replace the connectors. Also make sure there is no sign of damage to the gas line itself -- if rust, dents or cracks are apparent, replace the line.

Clean the Burners

• Years of boil-overs and spillage can take their toll on gas burners. If the gas outlets are clogged, the gas can't access the ignition spark to produce a flame. Remove the burner covers and clean the burner itself very thoroughly. Scrub it with a toothbrush or use a bent paper clip or toothpick to remove built-up gunk from the tiny holes that allow gas to exit the burner. If the burner still won't light after all the holes are clear, it's time to call in a professional.

Change the Bulb

• If your oven is working but the light doesn't come on, the bulb is probably just blown. Turn off the oven, wait for it to cool down and remove the bulb cover to replace the bulb. Use a bulb designed specifically for ovens, because the high heat can be dangerous for regular bulbs. Always replace the bulb cover before using the oven to prevent food splatters from reaching the bulb and its socket. If the light still doesn't work, you may have a door latch issue.

Test the Door Switch

• Try to run the self-cleaning cycle on your oven. If it doesn't turn on, it may men that the oven doesn't realize the door is closed. This may be an issue with either the door latch or the door switch. Tap the oven door handle while the door is closed. If it bounces or wobbles, the door latch is loose or broken and must be replaced. If it's securely closed, the problem is likely the door switch, which relays the door status to the electrical "brain" of the oven. Test it for continuity with a multimeter -- if it doesn't test, it may need to be replaced. Consult a professional for this job, especially if your oven is still under warranty.
