Description & Features
The Thermador PH42GWS professional wall hood brings commercial‑inspired performance and smart technology together in a sleek 42‑inch stainless steel design, ideal for serious home cooks who demand both power and style. Crafted to pair perfectly with 36‑inch professional ranges, its generous 42" width creates an extended capture area that helps draw in smoke, steam, and grease before they can escape into the kitchen, supporting cleaner air and a more comfortable cooking environment. One of the standout advantages of this model is its Wi‑Fi Enabled connectivity with the Home Connect® platform, allowing you to remotely monitor and control fan speeds and lighting, receive notifications when it’s time to clean the filters, and even integrate the hood with compatible smart home systems for a more seamless cooking routine. Another premium feature that sets the PH42GWS apart is the Powerfully Quiet® ventilation system design, which accepts your choice of integral, inline, or remote blowers; this flexibility lets you tailor installation for strong extraction while helping to keep operating noise to a minimum, so conversation can continue comfortably even when you’re cooking at high heat. For added convenience, the hood offers Automatic Mode and Delay Shut Off: temperature sensors can adjust fan speed automatically based on your cooking activity, while the delay function keeps the hood running briefly after you finish to help clear lingering odors, then shuts it down for you. Bright, multi‑level LED lighting is built in to illuminate the entire cooking surface with a crisp, even wash of light, and the sleek electronic touch control panel keeps operation intuitive and easy to wipe clean. Behind the scenes, durable stainless steel baffle filters work hard to capture grease and are dishwasher‑safe for quick maintenance, helping the hood maintain peak performance over time. With its professional aesthetic, advanced smart features, and thoughtful engineering focused on quiet yet powerful ventilation, the Thermador PH42GWS delivers a premium solution for homeowners looking to complete a high‑end cooking suite with a hood that looks as impressive as it performs.

Thermador Connected Experience by Home Connect™ – enables remote monitoring and control of fan speed and lighting, custom programs, and mobile notifications (including filter‑clean reminders) from your smartphone.

Wi‑Fi Enabled ventilation – connects to your home network so you can start, stop, and adjust the hood, and receive alerts, even when you’re away.

Hood Sync with Freedom® & Liberty® cooktops – allows compatible Thermador Freedom® and Liberty® induction cooktops to automatically turn on hood lighting and ventilation when cooking begins.

Powerfully Quiet® ventilation system – accepts integral, inline, or remote blowers (sold separately) to deliver strong smoke and odor removal while keeping operating noise to a minimum.

Professional Series design match – coordinates with Thermador Professional ranges and rangetops for a cohesive, pro‑style kitchen appearance.

42" Professional wall hood shell – sized to pair with 36" ranges and cooktops while providing extra overhang for improved capture.

27" extra‑deep capture area – extended depth canopy helps contain rising smoke, steam, and grease for more effective ventilation.

Four fan speed settings – lets you select precise airflow for simmering, sautéing, or high‑heat searing.

Automatic Mode ventilation – senses heat from the cooking surface and automatically adjusts fan speed to match your cooking intensity.

Delay Shut Off function – keeps the fan running for about 10 minutes after cooking to clear lingering smoke and odors, then turns off automatically.

Adjustable delay time via app – allows you to lengthen or shorten the post‑cooking run time through the Home Connect™ app.

Check filter reminder light – illuminates after a set number of operating hours to remind you when it’s time to clean the grease filters.

Dishwasher‑safe stainless steel baffle filters – heavy‑duty, commercial‑style filters capture grease efficiently and can be cleaned easily in a dishwasher.

Integrated grease collection tray – channels captured grease into a removable tray inside the canopy to help keep cabinets and cooking surfaces cleaner.

Infrared heat lamps – built‑in warming lamps keep cooked dishes warm on the cooking surface or a nearby shelf until you’re ready to serve.

Two multi‑level LED lights – bright, energy‑efficient LEDs provide even illumination over the cooking surface from first course to last.

Soft fading LED transitions – lighting gently brightens and dims for a premium, modern visual effect.

0–100% light level slider in app – allows fine‑tuned brightness control through the Home Connect™ app for task or ambient lighting.

Sleek electronic touch control panel – smooth, easy‑to‑wipe controls provide simple access to fan speeds, lighting, and timer functions.

Illuminated button controls – backlit controls are easy to see and operate, even in low‑light conditions.

Remote control ready (accessory) – compatible with an optional built‑in remote control panel so you can operate the hood from a more convenient location.

Vertical or horizontal ducting options – supports top or rear 10" round duct connections to suit different installation layouts.

10" round duct discharge – large duct size helps support high airflow performance and efficient venting to the exterior.

Ducted ventilation configuration – designed to exhaust air outdoors for maximum removal of heat, smoke, and cooking odors.

Built‑in / wall‑mount installation – mounts to the wall above a range or cooktop as a professional‑style focal point.

Stainless steel construction – durable, corrosion‑resistant stainless steel finish stands up to heavy cooking and wipes clean easily.

Low‑profile professional styling – chiseled edges and a recessed control panel deliver a bold yet refined look in modern or traditional kitchens.

42" width class – provides broad coverage over standard 36" cooking surfaces while fitting common 42" hood spaces.

18" hood height – offers substantial presence and capture volume without overwhelming standard wall spaces.

Required 30" clearance above cooking surface – ensures safe and effective installation height over ranges and cooktops.

Four‑stage speed settings – multiple fan levels allow you to balance ventilation power with noise and energy use.

Optional internal, inline, or remote blowers – compatible with a range of Thermador blower units (various CFM ratings) to match your cooking style and duct run.

Home Connect® remote monitoring – lets you check hood status, receive alerts, and confirm that the unit is off when you’re away from home.

Smart home integration – works with select smart home services such as Amazon Alexa for voice‑activated control of fan and lights.

Clean filter notifications – sends reminders to your mobile device when it’s time to wash the baffle filters, helping maintain peak performance.

ADA‑friendly operation when properly installed – can be configured with remote controls and appropriate mounting height to support accessible use.

Included backdraft damper – helps prevent outside air from flowing back into the kitchen when the hood is not in use.

Optional duct cover accessories – compatible with 6" and 20"–54" telescopic duct covers (sold separately) to conceal ductwork up to higher ceilings.

Optional roof and wall caps – can be paired with matching Thermador roof plates and wall caps (sold separately) for a complete venting solution.
