Parts for Whirlpool GW399LXUS05: 01 - Cooktop Parts

This control knob lets you set a burner's heat level on many gas cooktops/ranges. A worn or broken knob can make temperature adjustments difficult or impossible—replacing it restores smooth, accurate control.

• Turns the surface burner valve stem to adjust flame/heat
• Common failure signs: cracks, stripped insert, knob won't grip shaft, missing or hard-to-turn knob
• Cosmetic wear or discoloration on the old knob
• Restores clear pointer alignment and tactile feedback

• Disconnect power and allow burners to cool before replacing
• Pull the old knob straight off the valve stem; align the new knob's insert with the flat on the stem
• Press on firmly until fully seated—do not force or twist on misaligned

This sheet-metal pan-head screw secures appliance panels, brackets, and components to the cabinet or frame. Replacing a missing or damaged screw restores a tight fit and helps stop rattles, misalignment, and loosening.

• Fastens sheet-metal panels, covers, ducts, and brackets to the appliance chassis
• Helps keep components aligned and secure during operation
• Replace if the original is missing, rusted, stripped, or damaged
• Common symptoms: loose or vibrating panels, gaps or misaligned parts, hardware that won't tighten

• Disconnect power; shut off gas or water supply before servicing
• Support the panel or part being attached; hand-start threads to avoid cross-threading
• Use the correct driver bit; tighten snugly but do not overtighten into sheet metal
• If multiple matching screws secure a part, consider replacing them as a set for consistent hold

This membrane switch is the thin keypad mounted behind the control console that sends your button presses to the electronic control. Replacing a worn membrane restores reliable input when keys stop responding or register intermittently. What it does:

• Detects button presses and relays them to the control board
• Common fix for unresponsive or intermittent keys
• Can address "stuck key" beeping or key-related error indications
• Restores ability to select settings and start/stop functions

• 1 membrane switch

• Disconnect power before servicing; on microwaves, high voltage can remain—use proper discharge procedures.
• Remove the control panel/console to access the keypad.
• Handle the ribbon cable carefully; fully seat the connector.
• Clean the mounting surface and align the new membrane before pressing into place.

This control knob replaces a worn or missing knob on your range or cooktop, allowing you to select heat and function settings smoothly again. Restore precise control and a clean, finished look with a direct-fit replacement.

• Attaches to the control shaft of a valve or switch to select burner/heat settings
• Restores smooth, positive engagement if the old knob is cracked, stripped, or loose
• Helps resolve issues like slipping, wobbling, or difficulty turning settings
• Ideal when the original knob is missing or its markings are no longer readable

• Disconnect power at the breaker and shut off gas before servicing
• Pull the old knob straight off; avoid prying against the control panel
• Align the new knob with the stem orientation (set stem to Off if keyed) and press on firmly
• Verify smooth operation through all settings after installation

Replacement burner cap for the 4-inch sealed gas burner on your cooktop. Restores proper flame shape and helps keep the burner head clear of spills and debris for reliable ignition and even cooking. What it does:

• Covers the burner head to promote an even, focused flame for consistent heat distribution.
• Helps prevent food and liquid from entering the burner assembly and interfering with ignition.
• Can resolve common symptoms like uneven or yellowing flame, lifted flame, or a burner that doesn't heat evenly when the cap is damaged or missing.
• Fits onto the burner post and works with the existing burner head and igniter to maintain normal operation.

• Allow the cooktop to cool completely and turn off the gas supply or power to the appliance before servicing.
• No tools are normally required; remove the old cap and seat the replacement cap flat on the burner head.
• Make sure the cap is properly centered—misalignment can cause ignition issues or uneven flame.

This auxiliary surface burner head mounts over the orifice on your gas cooktop/range and distributes gas through precision ports for an even flame. Replacing a clogged or damaged head restores fast ignition and consistent heat on the small burner. What it does:

• Distributes gas through ports to produce a stable, even flame on the auxiliary burner
• Interfaces with the igniter electrode for quick, reliable lighting
• Common symptoms of a worn/clogged head: burner won't ignite or clicks without lighting; weak, uneven, or yellow flame; delayed ignition
• Helps restore proper simmer performance after corrosion, warping, or blocked ports

• 1 auxiliary burner head

• Shut off gas and disconnect power; allow the cooktop/range to cool completely
• Remove grate and burner cap, then lift off the old head; clear debris from the orifice and around the igniter (do not enlarge burner ports)
• Position the new head over the orifice and igniter; align locating features and seat fully; if your model uses screws, tighten them evenly without over-torquing
• Reinstall the cap and grate, restore gas/power, and verify even flame and normal ignition

The Burner Head is an OEM part for Whirlpool ranges. It is responsible for distributing gas to create an even flame for cooking on the stovetop. This burner head ensures efficient gas flow and optimal flame control, which are essential for consistent cooking performance.

Causes of a bad burner head can include clogging from food debris or grease, corrosion due to prolonged exposure to heat and moisture, or physical damage from impact. Such issues can obstruct gas flow and result in uneven heating or poor flame quality.

Symptoms of a bad burner head include:

• Uneven flame or poor flame control
• Difficulty igniting the burner
• Low or inconsistent heat output
• Unusual noises such as hissing or popping during operation

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

This burner head mounts on the cooktop and distributes gas evenly to produce a steady flame. Replacing a worn or damaged head restores proper flame pattern and helps your burner light quickly and cook consistently.

• Directs gas through precisely sized ports to create an even flame
• Can resolve issues like uneven flames, yellow/orange flames, or delayed ignition
• Helps when the burner won't light or only lights partially
• Replaces a corroded, clogged, or warped burner head

• Disconnect power and shut off gas supply before servicing
• Allow the cooktop to cool completely
• Lift off the grate and cap; remove the old head and align the new head on the burner base
• Ensure ports are clean and seated correctly; test for proper ignition and flame
