# La Cornue surface burner and igniter service

### About burner and igniter work on brass burners

The brass burner assemblies on these ranges come apart for cleaning, which is one of the pleasures of owning one and the leading cause of this call: they go back wet, or slightly off their seats, and in a kitchen at eighty per cent humidity a splashed electrode can take a day to dry. Beyond that it is ports, caps, crowns, the electrode and its ceramic — small parts, reached from the front, and normally one visit. The ignition module is tested rather than swapped, because it is the expensive part and it is rarely the answer.

What this involves

One burner out is the electrode or the ports — not the module

Yellow flame is air mix, fuel or an orifice, and it is measurable

Ports cleared properly rather than poked at

Which burners, and since when

All of them points at the module or the supply. One of them points at that burner.

The electrode and its ceramic

Moisture after a cleaning, a cracked insulator arcing to the wrong place, a gap that has opened up.

The ports and the cap

Cleared and seated. A flame that cannot travel around the crown cannot reach the spark.

The orifice and the air shutter

This is where a yellow flame is actually fixed, and where a bad propane conversion shows itself.

Light it cold and hot

A burner that lights from cold and sulks when the range is hot is a different problem, and testing only once misses it.

### Should I clean the ports myself?

Cleaning caps and crowns with hot water and a soft brush is ordinary maintenance and it fixes a share of these calls, so yes. Two rules: never push wire or a pin into a port, because an enlarged port changes the flame permanently and turns a free fix into a part; and let everything dry completely before reassembly, or you will have created the problem.

### How do I tell the module from the electrode?

Count the burners. A failed ignition module takes every burner with it; one dead burner is that burner's electrode, ceramic or ports. It is a ten-second observation and it is the most useful sentence you can give us on the phone.
