Built-in hob vs gas stove: why repairs are a different job

A built-in hob and a countertop stove burn gas the same way. The difference is everything around the flame — and that is what makes a hob repair a different visit.

Access

A stove can be lifted onto a table and turned over. A hob is sealed into a cutout with its valves, ignition and gas inlet underneath, reached through the cabinet below. Most hob work happens lying on the kitchen floor with a torch.

Flame-failure devices

Nearly every hob has a thermocouple at each burner that shuts the gas if the flame goes out. Stoves mostly do not. These devices are the single most common hob fault — and the reason a hob burner 'goes out when you let go of the knob'.

Mains ignition

Hobs are almost always plugged in rather than battery-powered. That adds a plug, a socket under the counter and a module that a stove would not have.

The gas connection

Usually a rigid or braided connection to a wall point rather than a rubber pipe to a cylinder. Better, but harder to inspect without pulling the hob.

If a hob repair requires lifting the unit out of the counter, the sealing strip underneath should be replaced when it goes back. Reusing a compressed seal lets spills reach the electrics below.

What this means for you

Expect a hob visit to be longer than a stove visit for the same symptom, and to involve the cabinet under the counter being emptied. Clearing it before the technician arrives saves everyone twenty minutes.
