Château® Burner Won’t Ignite Safe Things to Check First

A use-and-care manual for the Chateau series describes burners with a safety thermocouple, so gas to a burner is cut off automatically if its flame goes out. To light one, you press the knob in, turn it left to the high-flame position and hold it for about 3 to 10 seconds. The same manual says the thermocouple may take longer the first time. Cooking tips for these ranges add that the burner cap must be locked in position or the burner will not ignite.

CornuFe dual-fuel ranges work on a similar principle, with a flame supervision device that stops the gas if the flame goes out and a hold time of around 4 seconds while the igniter sparks. If you have not used the cooktop in a while, or the range was just installed, air in the gas lines can delay lighting. The Chateau manual says burners may need to be operated one after another until the air is purged, which can take 1 to 5 minutes.

Many owners hear sparking at a burner they are not lighting and assume something has failed. The CornuFe manual says pressing one burner knob makes sparks at every burner, and the Chateau manual says a sparking noise means the ignition system is operating normally. So the click proves the igniter is working, not that gas is reaching the burner or that the head is clean.

Pay attention to what happens after you release the knob. If the flame goes out immediately, the manual says to set the knob to off, wait one minute and try again, holding the knob a little longer. The Chateau manual also says the control should not be held for more than 15 seconds; if the burner has not lit by then, stop, wait at least a minute and retry.

Start with the burner cap. Let everything cool first, then lift the cap and set it back so it locates in the base. The CornuFe manual says heads must seat correctly, with two pips fitting two notches, and that parts must be completely dry before they go back. Damp parts can leave a burner clicking without lighting after a cleaning.

Then look for blockage. The cleaning tips say to wash gas burner caps in warm soapy water and make sure every hole around the cap is free of grease and debris. The manual says blocked ports can be cleared with fuse wire, but use a light touch and never work around a burner while another burner or the oven is on, because the ignition system can shock you.

Last, confirm the power is on. The cooktop needs electricity to spark, so a tripped breaker or a power cut will leave you with no click. During a power failure, the CornuFe manual describes lighting a cooktop burner with a match, while the Chateau gas oven manual prohibits lighting the oven with a match. Read the exact steps in your own manual before trying either.

When a burner does light, glance at the flame. The Chateau manual says natural-gas flames should be bluish with at most a slight yellowish fringe, and propane may look softer with yellowish tips. A long flame with a white tip means call for service. A weak or lopsided flame can also come from debris around the ports, so clean first and watch again.

If the burner still will not light after a reseated cap, clear ports and a correctly timed hold, the cause is beyond what an owner should chase. Valves, thermocouples and igniters sit inside the cooktop, and the manuals leave that work to qualified service people. Do not keep pressing the knob in a loop, and never force a burner with a flame source other than the one the manual describes.

If you smell gas, do not light appliances, touch electrical switches or use a phone inside the building. Leave, then call the gas supplier or fire department from outside. When you book, give the model label, which burner is affected and what you tried.

Why does my Chateau burner click but not light?

The igniter is working, since clicking is normal operation. The more likely causes are an unseated cap, blocked ports, a damp part or a knob released too soon.

How long should I hold the knob?

The Chateau manual says about 3 to 10 seconds, and not more than 15. The CornuFe manual gives about 4 seconds. Check your own manual for the number that applies.

Is it normal for all burners to spark at once?

Yes. One CornuFe manual says pressing a single knob can spark at every burner.

Can I use a match during a power failure?

Only where your manual describes it. The CornuFe cooktop allows it with specific steps, but the Chateau gas oven prohibits it.
