Symptom
Thermador range burner will not light
A burner that clicks and clicks without catching, or one that lights and goes straight out. On a professional gas top most of these are a cap out of place or ports blocked after a boil-over.

Five ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The burner cap out of position
A millimeter out and the flame will not carry round the ring. The commonest single cause and it costs nothing to correct.
-
Ports blocked after a boil-over
Dried sugar or starch in the ring of holes under the cap. A pin clears them — anything that widens a port does not.
-
A cracked electrode
Liquid gets into the ceramic and it cracks. It sparks weakly or in the wrong place, and it is an inexpensive part.

Moisture across the ignition system
Everything clicking at once, including burners you are not using. It usually clears once things are properly dry.
-
The spark module
When it is not moisture and not one burner, this is the part behind all of them.

01
Take the cap off cold and look
At the ring of ports underneath. Clean them with a pin, wipe the cap, and put it back seated properly.
-
02
Dry everything thoroughly
Especially after a wash or a spill. Then try again — many all-burners-clicking calls end here.
-
03
Try the burner with a match
If it lights and burns cleanly by hand, the gas side is fine and the problem is ignition — which is the cheaper half.
-
04
Look at the flame color once lit
Blue and steady is right. Yellow or lifting off the ports is a combustion issue and worth a call rather than a wait.

About Thermador range burner will not light
There is no code for this, and there does not need to be
Gas burners are mechanical, so the diagnosis is in what you can see. One burner clicking and not lighting is that burner: its cap, its ports, its electrode. Every burner clicking at once is the ignition system as a whole, usually after a spill or a wash.
The cheap causes are the common ones
Caps, ports and electrodes account for most no-light calls on a professional gas top, and none of them is expensive. The cap has to sit exactly where it belongs; a boil-over that dried in the ports does the rest. Both are cleaning rather than parts, and both are things you can do this afternoon.
When to stop and call
- A smell of gas at any point — that is a call before anything else
- A yellow or lifting flame, which is combustion rather than convenience
- A burner that lights and then goes out, which points at the flame sensing rather than the spark
- Every burner clicking constantly after everything is dry

Before you book
Questions about thermador range burner will not light
It clicks forever even after the burner lights.
Usually moisture around that electrode, or a cap not fully seated so the flame sensor never confirms. Dry it and seat the cap; if it continues, the electrode is the next suspect.
Can I use a match in the meantime?
On most of these, yes, and it also tells you something useful: a burner that lights and burns cleanly by hand has a gas supply and a clear port, which points the diagnosis at ignition.
The flame is yellow.
Worth a call rather than a wait. Yellow means incomplete combustion — air adjustment, a blocked port, or the wrong orifices after a conversion between natural gas and propane.
