# Bosch gas burner & igniter repair

### The fastest diagnosis on the site

One burner misbehaving is that burner — the cap, the ports, the electrode. All of them at once is upstream, at the ignition module or the supply. Establishing which takes a few seconds and it removes most of the possibilities.

### What you can do before calling

With the burners off and cold: lift the cap, check it sits flat and square in its recess, and look at the ports for anything baked into them. A boil-over that dried into the ports is the most common cause of a burner that lights unevenly, and clearing it costs nothing.

### The flame is the instrument

A blue flame sitting on the burner is right. Yellow, lazy or lifting away from the ports means air, pressure or a partially blocked burner, and it is worth acting on — not because it is dangerous today, but because it is the cheapest moment to fix it.

What this involves

Igniters, electrodes and the module

Burner caps, ports and the flame itself

Gas oven igniters that fail slowly

One burner or all of them

One is the burner: cap, ports, electrode. All of them is upstream: the module, the supply or the wiring. It takes a second to establish and it decides everything after it.

Cap and ports, cold

A cap a millimeter out of position stops a burner catching, and a boil-over blocks the ports. Both are free to fix and both are worth checking yourself before you call.

The spark and the flame

Electrode condition, the spark itself, and then how the flame sits — a yellow or lifting flame is telling you something about air or pressure rather than about the igniter.

Every burner, lit and held

Including on low, which is where a marginal burner gives itself away.
