# The Broil Symbol on a La Cornue, and Why Browning Fails on Its Own

## La Cornue oven broil setting: the symbol, first

A single **bar at the top** of the icon: heat from the roof of the cavity only. That is broil.

Two related ones get confused with it. A **bar at the top with a fan** is fan-assisted browning — the broil element with air moving, which colors a larger area more evenly and is gentler. **Two bars, top and bottom**, is conventional baking with both elements and no fan; that is not broiling, and choosing it to brown something gives you a hot oven and a slow result.

## Why this matters more on a La Cornue

Because of an arrangement most owners never have explained to them.

Every vaulted gas oven on this make carries an **electric** broiler above a **gas** bake burner. Two heat sources. Two separate switched circuits. One cavity.

The practical consequence is that browning and baking are independent. A range can brown perfectly and refuse to bake, or bake perfectly and never brown, and owners describe both as "the oven is half working" — which is exactly right.

## The free diagnosis

This is the useful part of the page.

**An oven that broils but will not bake** has already proved four things: it has power, its control works, its door is closing, and its temperature sensing is alive. All of that is common to both circuits. So the problem is in the bake half alone — on the gas side that is the igniter, the safety valve or the thermocouple, and on the electric side the bake element or its terminals.

**An oven that bakes but will not brown** is the reverse, and simpler: the broil element or its circuit.

Either way, one sentence on the phone narrows the visit before anybody sets off, and it takes about a minute to establish.

## How to actually use it

**Preheat the broiler for three to five minutes.** The element is radiating from the moment it is switched on, but the roof of the cavity is not, and on a radiant oven that second contribution is worth having. It is the difference between color and color with some cooking underneath it.

**Door closed.** The habit of propping the door open comes from ovens with a separate broiler drawer, where a thermostat would otherwise cut the element out. A vaulted cavity is designed to be sealed and works better closed. The maker's own answer to hot knobs, incidentally, is specifically not to leave the oven door open.

**Top shelf, with room.** As close to the element as the food allows.

**Be in the kitchen.** On a Château gas oven there is no window in the door, so broiling is the one job where you check by opening rather than by looking. Nothing about a broiler on any appliance rewards leaving the room.

## When it is the element and when it is not

On the **electric** side, a broil element is measured cold and under load. An open circuit is unambiguous; a partly failed element heats and stalls, which reads as weak browning rather than none.

While we are in there, the **terminals and supports** get looked at. That is where elements actually fail — twenty years of heating and cooling at a connection — and a burnt terminal block will destroy a new element as efficiently as it destroyed the old one. Replacing the element and leaving the cause is a part bought twice.

On the **multifunction** platforms there is a control in the path as well, and it gets proved rather than assumed: a board condemned with a failed element still attached fails again on the first cycle.

## One thing not to conclude

Weak browning on one side of the food is not automatically a broiler problem. A vaulted oven is graded by design, the maker's own notes ask you to turn a large item during cooking, and an unlevel range puts food closer to one radiating surface than the other — the dish-of-water test on a shelf is free and it is the manufacturer's own first check.

Rule that out, then blame the element.
