--- title: "Rangetops" description: "La Cornue rangetops: a rangetop is the top half of a La Cornue sold in its own right: the same brass burners, the same plaque coup de feu, the same" url: "https://la-cornuemiami.support/appliances/rangetop/" date_modified: "2026-09-03" Appliance type: "Rangetops" --- # La Cornue rangetops ### The same top, sold without the range under it T48 for the Grand Palais 180 at 1800 mm, T46 for the 165, T45 for the 150, T43 for the Châtelet 135, T42 for the 120, T49 for the Grand Castel 90, T47 for the Castel 75 and T40 for the Castel 60. All of them 700 mm deep and 200 mm high, dropping into a counter. Weights run from about 121 lb uncrated on a T40 to 290 lb on a T48 — against 710 lb for the range of the same width, which is the practical difference between the two appliances when anything has to move. The configuration codes are the range’s own, so a T45 can arrive in any of nine top layouts and the code is what says which modules are actually in the frame. ### What a rangetop cannot do, and what that means for a repair It has no ovens. So there is no oven thermostat to drift, no vaulted cavity, no door seal to harden, no oven igniter and no electric broiler — which removes about half the failure list of a range at a stroke. What is left is the top: brass burners and their electrodes, the gas valves and their stems, the plaque and the burner beneath it, the grill module and its rock bed, induction coils and their generator, and the teppanyaki element. Every one of those is reached from the front with the unit in place. It also means a rangetop kitchen usually has a second appliance doing the baking, and on this make that is either a Château Tourelle wall oven or somebody else’s oven entirely — worth telling us which. ### The confusion worth clearing up before a visit “Range top” and “cooktop only” are both things people type, and on most makes they mean the same appliance as a cooktop. On La Cornue the rangetop is its own product line with its own price list entries, and the owner of this site asked for it to be its own page for that reason. So: if there are oven doors under it, you have a range. If it sits in a counter with cabinetry or a drawer beneath, you have a rangetop. If it is a ceramic panel with no brass on it at all, you have either a T40 or the induction module of a mixed top. Those three answers send different parts to your kitchen. T40 to T48 · 200 mm into the counter · the same modules, no ovens beneath Rangetop repair T40 to T48 — the same configuration codes as the range No ovens, no oven thermostats, no door seals Much lighter than a range, so the one job that prices weight rarely applies The same top, sold without the range under it T48 for the Grand Palais 180 at 1800 mm, T46 for the 165, T45 for the 150, T43 for the Châtelet 135, T42 for the 120, T49 for the Grand Castel 90, T47 for the Castel 75 and T40 for the Castel 60.

If it is a ceramic panel with no brass on it at all, you have either a T40 or the induction module of a mixed top. Those three answers send different parts to your kitchen. ### Is a rangetop repair the same as a range repair? For the cooktop itself, yes: a plaque is a plaque and an induction zone is an induction zone whether there are ovens beneath it or not, and the configuration codes are the same — N1 to N9 on a 180, K1 to K6 on a 150, B1 to B3 on a 75. What differs is everything else. There are no oven thermostats to drift, no vaulted cavities, no door seals and no igniters for an oven burner. So the diagnosis is narrower, and a booking that says rangetop rather than range saves us bringing parts for an oven that does not exist. ### Ours is set into a stone counter. Does that make access difficult? Less than people fear, and it is the reason to say so before the visit. The modules lift out and the controls are reached from the front, so most work on a rangetop happens without disturbing the counter at all. What does need planning is anything requiring the unit to come up out of its cutout — a stone counter is somebody's fabrication and a rangetop sealed into one is not something to lever at. Tell us the counter material when you book and we will bring what the job actually needs. ### Can a rangetop have ovens added underneath later? Not by converting it. A range is a different appliance with a different body, a different frame, adjustable legs and cavities built into it — a T45 is 200 mm high and a G45 stands 914 mm on its legs. What people do instead is pair a rangetop with a Château Tourelle wall oven in a cabinet run, which is exactly what the Tourelle was designed for. That is two appliances, and we service both. ### The Castel 60 rangetop has no burners at all. Correct, and it is the one member of the family that is induction by definition rather than by option: a large induction hob with four cooking zones, integrated induction controls and a flush integrated backsplash, ordered as T40USAA. So it is the only rangetop where all three of the error codes this make publishes — E2, U400 and Er with a number — are always the relevant vocabulary, and where none of the gas diagnostics apply. --- **[Read full article: Rangetops](https://la-cornuemiami.support/appliances/rangetop/)**
