# Why one burner clicks and will not light while the others are fine

One burner clicking without catching is a local fault. Every burner clicking without catching is a supply question, and the two lead to very different visits.

The most useful thing you can tell us about a burner that will not light is how many of its neighbours are doing the same thing, because that single fact splits the diagnosis.

A burner that clicks and will not catch is the most common call we take, and it
is also the one where a single sentence from the customer does most of the
diagnostic work. That sentence is how many burners are affected.

One burner misbehaving while its neighbours light normally is a local fault, and
the fault is within a few inches of the burner itself. Every burner clicking and
none of them catching moves the question upstream to the gas supply. Those are
two entirely different visits, and it is worth sorting out which one you have
before you call.

## When it is one burner

Three causes account for nearly all of it, and all three are small.

The first is a blocked port. Burners have a ring of small holes, and the ones
near the electrode are the ones that matter for lighting. Something boiled over,
ran into a port, and dried there. The burner will often still light on a high
setting because enough gas gets out elsewhere and the flame travels round, and
it will refuse on a low setting because there is not enough to start with.

The second is a cap sitting out of true. Burner caps have a seat, and they only
work in one position. After a clean, a cap can go back a fraction proud or a few
degrees rotated, and the ports are then no longer where the spark is jumping.
The burner looks completely normal. It clicks and clicks and lights late or not
at all. Lifting the cap and setting it down properly fixes an astonishing number
of these.

The third is the electrode. It is a small ceramic-insulated pin sitting in the
grease and steam of a working kitchen, and over time it picks up a film. The
spark still happens and it is weaker, and a weaker spark lights cold gas less
reliably. This is the cause behind the classic complaint of a burner that will
not light first thing in the morning and behaves perfectly by lunchtime, because
a cold kitchen is a harder place to light gas than a warm one.

## When it is every burner

If nothing on the top will light, look at what else in the house uses gas. If
the water heater is also cold, the problem is not the range and the call should
go to the gas utility rather than to us.

If everything else is fine and only the range is affected, the question is
whether the range is getting the pressure it needs. That is not something to
assume from the meter, because a regulator that has drifted low will still keep
a furnace and a water heater perfectly happy and still starve a large range. We
measure it at the appliance.

There is one more possibility worth naming, which is that the range is not
getting any spark at all rather than not getting gas. If you can hear clicking,
there is a spark module working. If there is no clicking anywhere, the module or
its supply is the place to start, and that is an electrical fault on a gas
appliance.

## Clicking that will not stop

A separate complaint, and a common one: the burner lights normally and the
clicking carries on afterwards.

On these appliances the same electrode that lights the flame is often used to
confirm that the flame exists, by passing a very small current through it. A
lit burner conducts. If the electrode is dirty, wet or bent slightly away from
the flame, the control cannot detect the flame it just lit, so it keeps trying.

It is harmless and it is maddening, and it is usually cured by cleaning the
electrode back to bare ceramic and metal and checking its position relative to
the burner.

## The simmer that will not hold

Last, the fault that is not really an ignition fault at all. A low flame has
very little energy holding it to the port, so anything that disturbs it puts it
out, and the causes stack rather than acting alone.

A slightly blocked inner ring, plus a supply pressure that has drifted a little
low, plus a low-flame adjustment that was never set for this house, will
together kill a simmer that would have survived any two of the three. That is
why we check all three rather than adjusting the first thing we find. Fixing one
of them can make the simmer hold on a cool morning and fail again in August, and
then everybody has wasted a visit.
