La Cornue Château 120 WD Range Repair in San Francisco

The Château 120 WD at a glance

The Château 120 WD range belongs to the Château G4 series and measures 47 1/4 inches across. The 120 in the name is the width in centimetres, and it is among the larger ranges in the series, which tells you something about the kitchen it lives in. Cabinetry, the floor, the gas run and the hood above it were usually planned around it.

It is a current model. Our work on it sits under La Cornue range repair, and the broader lineup is described in La Cornue ranges.

What owners call us about

On a range of this width the complaints tend to be about coordination between parts rather than a single dead component. A burner on one side lights while the other side clicks and waits. The oven reaches the dial setting slowly, or the cavity cooks unevenly from left to right. A door that no longer sits flush lets heat escape around the frame. Knobs turn stiffly, and a trim piece loosens after years of cleaning.

Why the width changes the installation story

A 47 1/4 inch range is heavy, and the way it is carried matters. In San Francisco that often means a floor with some slope, a flat in an older building where the gas line was extended during a remodel, or a hillside house where the supply pressure at the appliance is not what the plan assumed. A range that has settled out of level can show up as a flame that favors one side or a door that drifts open.

Checks you can safely make

• Confirm the range has power and that its breaker has not tripped.
• Remove each burner cap and head, let them dry, and set them back so they sit square.
• Close the oven door slowly and watch whether it meets the frame evenly all the way around.
• Write down exactly what the display or the burner does, and when it started.

Stop there. If you smell gas, leave the house, avoid switches, and call the gas utility or 911 from outside. If you notice a burning smell or sparks, switch the range off at the breaker.

Giving us the right identification

Parts for these ranges are specific to the brand, and the 120 WD has neighbors in the same series that look similar from across the room. The plate with the full model and serial information is the reliable way to tell them apart. It is usually behind a lower door or drawer, or on the frame behind the oven door. Photograph it and send it with your request. Neighbors such as the Château 120 range look alike, and our guide to finding the model number shows where to look.

What the visit looks like

We test ignition, flame behavior and oven performance on the range itself. You get a written estimate for what we found, and nothing is repaired until you approve it. Related reading: burner won’t light and oven not heating.
