Description & Features
The Thermador CET305YB electric cooktop brings professional‑grade performance and a sleek, frameless look to any modern kitchen, combining advanced cooking technology with intuitive controls in a 30‑inch width that fits seamlessly into most standard countertops. Its black glass surface creates a clean, minimalist aesthetic that pairs beautifully with both contemporary and classic cabinetry, while the smooth ceramic top makes everyday cleanup fast and effortless. At 31 inches wide, this cooktop offers four radiant elements and eight flexible cooking zones, giving you generous space to manage multiple pots and pans at once without crowding.

What truly sets the CET305YB apart is its innovative CookSmart® technology, which uses a built‑in sensor and four preset frying levels to automatically regulate pan temperature, helping you achieve perfectly seared meats, golden pancakes, and delicately sautéed vegetables with far less guesswork than on a conventional electric cooktop. Complementing this is the Dual Zone Bridge element, an exclusive Thermador feature that links two round cooking zones into one extended heating surface, ideal for griddles, grill pans, and oblong cookware that standard round elements struggle to heat evenly. At the center, a powerful Triple Element groups three differently sized heating zones in a single location, allowing you to match the active element precisely to the diameter of your cookware, from small saucepans to large stockpots, improving efficiency and reducing energy waste.

Control is handled through an Illuminated Touch Control Panel that is seamlessly integrated into the glass surface, offering 17 precise power levels with crisp, easy‑to‑read blue illumination. This touch interface not only simplifies selecting heat settings and timers, it also includes a wipe protection function so you can quickly clean the panel without accidentally changing your cooking settings. A dedicated cook timer for each zone helps you coordinate complex meals, while residual heat indicators clearly show which areas of the surface are still hot, adding an extra layer of safety for busy households. With its combination of sensor‑guided CookSmart® frying, Dual Zone Bridge flexibility, and a versatile Triple Element, the Thermador CET305YB delivers a premium cooking experience that stands out from typical smooth‑top electric cooktops in both performance and design.

CookSmart® frying sensor technology – uses a built‑in sensor with 4 preset frying levels to automatically regulate pan temperature for consistent, perfectly cooked results and reduced risk of scorching.

Dual Zone Bridge element – exclusive Thermador feature that connects two round cooking zones into one larger zone, ideal for griddles, large oval roasters, and other oblong cookware for even heating.

Triple Element cooking zone – combines three concentric heating zones in one location so you can match the active element size to small, medium, or large pots and pans for better efficiency.

Illuminated Touch Control Panel – seamlessly integrated glass touch controls with blue illumination provide intuitive power selection, clear feedback, and a smooth surface that’s easy to wipe clean.

Black Glass frameless design – sleek, edge‑to‑edge black ceramic glass surface without a metal frame delivers a modern, built‑in look that complements contemporary kitchen styles.

Four radiant elements with eight cooking zones – offers multiple element sizes and configurations to accommodate everything from small saucepans to oversized cookware on a compact 30" cooktop.

17 power levels – fine‑grained heat control lets you precisely adjust from gentle simmering to high‑heat boiling for a wide range of cooking techniques.

Cook timer for each cooking zone – allows you to set a specific cooking time for a zone and automatically turns the element off when the time has elapsed to help prevent overcooking.

Automatic shut‑off safety – turns elements off after a set period or when a timed program ends, adding peace of mind during busy cooking.

Residual heat indicators – clearly show which cooking zones are still hot after use so you can avoid accidental burns and use residual heat efficiently.

Child lock function – disables the touch controls to prevent children or unintended touches from turning on or changing settings while you’re not watching.

Wipe protection function – temporarily locks the control panel so you can wipe spills and splatters from the glass surface without accidentally changing power levels.

Two‑ring and triple‑zone flexibility – multi‑ring elements adapt to different pan diameters, improving energy efficiency and heating performance by matching heat to cookware size.

30" width with 4, 2‑ring / triple‑zone layout – maximizes usable cooking space in a standard 30‑inch cutout, making it suitable for most kitchen renovations and replacements.

High total power output (up to 7,800 W) – delivers strong heating performance for rapid boiling, searing, and high‑heat cooking when needed.

MultiTouch control interface – dedicated touch keys for each zone and function simplify operation, allowing quick adjustments without knobs.

Integrated kitchen timer – built‑in timer can be used independently of the elements to track overall cooking or baking times.

Standard 240/208 V electric connection – designed for typical North American electric cooktop installations, compatible with most existing 30" electric cooktop circuits.

Low‑profile surface‑mount installation – thin glass profile sits nearly flush with the countertop for a clean, minimalist appearance and easier cleanup around the edges.

Smooth glass‑ceramic surface – flat, continuous surface makes it easy to slide pots between zones and quickly wipe away spills once the surface has cooled.
