Whatever badge is on the door, this fault comes down to a short list of specific, repairable causes. Here is what they are, what you can check before calling, and where to find the version written for your brand.

Controls gas flow to the burner and can fail independently of the igniter.

The causes above hold across the board, but the layout, the part numbers and the diagnostic sequence differ by manufacturer. We have written this fault up separately for 12 brands — pick yours for the version specific to that stove.
These are the components our technicians check first on a symptom like this. The exact part depends on your make, model and what we find during diagnosis.
