Two of gas burners will not light - Cooktops

Usually that's caused by clogged holes in the burners. I clean it out using a toothpick.

It probably has a flame failure device..
This is to cut off the gas if the flame goes out..
When you light the burner, the flame heats a sensor which keeps the gas on, if this is faulty, the gas will go out.

All gas burners will put off a gas Oder when lit, if you go away for a while and come back home and smell gas, you should turn off the gas and call the gas company

Hello there:
A burner doesn't work The most common problem for gas surface burners is that they get gas but don't light. This is generally caused by dirt or grease splatters on the burner itself. Residential-grade range/stove burners are round and have small holes around their perimeter to allow gas to flow out and create a round flame. The gas coming from these holes is often ignited by a small vertical row of holes on the side of the burner. If these vertical holes are clogged or obstructed, the gas can't ignite. The solution is to clean the burners thoroughly. Use a toothpick to clear the small vertical holes, then allow the burner to dry completely and try lighting it again. If it doesn't light immediately, either repeat the procedure or call a qualified appliance repair technician.

Most gas range tops no longer have pilot lights but use an electronic ignition (sparker) to light the burner. Normally when you turn the burner on you should here a snapping or sparking sound, at which point the burner should ignite. Here is a link to the user manual for 36" - 5 burner Thermador rangetop...maybe this will help: http://dl.owneriq.net/a/ac64ae7b-1ed3-44a3-9235-e4dbd8fe4628.pdf

By the way, in the short term you could always use a match to light the burner. JUST BE VERY CAREFUL THE YOU HAVE THE MATCH LIT AND OVER THE DESIRED BURNER BEFORE YOU TURN KNOB TO START THE BURNER!!!!

Make sure the little tiny flash holes are open. They allow a little bit of gas to seep out so the igniter can light the burner. If you can light the burners with a match, check those holes.
If yours are the "sealed" type burners, make sure they are not a half a turn out (180° around)

There are a series of holes in the burner leading down from the main flame area to the pilot tube, ensure the holes are not plugged/restricted.

Clean the gas nozzle w/small wire are located at the back of the gas cook top /shut off the gas clean small gas nozzle clog / w moisture /rust dust and any foreing material.

Replace that ignitor on that burner only. Not drawing enough amps to spark properly.
