Compatibility / Fits Models

Weber 64666 fits select 2022 and newer GENESIS 300 Series grills originally equipped with stainless steel cabinet doors.

Confirmed applications include select:

• GENESIS E-325s
• GENESIS S-325s
• GENESIS E-335
• GENESIS S-335
• GENESIS SX-325s Smart
• GENESIS 300 Series Special Edition configurations

For example, Weber's official schematic for GENESIS SX-325s Smart model 35500001 lists 64666 as the left-hand stainless steel door.

The part is also confirmed on Weber's natural-gas model 37400001, showing that 64666 is used on compatible configurations regardless of fuel type when specified by the factory schematic.

Fits most grills within this series—confirm model number before ordering.

Important: Stainless Steel vs. Black Doors

The 2022+ GENESIS 300 platform uses different door part numbers depending on the grill's factory finish.

For stainless steel configurations:

• 64666 – Left-Hand Stainless Steel Door
• 64667 – Right-Hand Stainless Steel Door
• 68734 – Stainless Steel Door Kit

For black-door configurations, Weber uses:

• 64479 – Left-Hand Black Door
• 64478 – Right-Hand Black Door
• 68733 – Black Door Kit

For example, Weber's SP-E-335 schematic lists 64479 and 64478 for its black cabinet-door configuration rather than 64666 and 64667.

This makes it important to match both the model number and original door finish before ordering.

Installation / Use Instructions

1. Turn off the grill and gas supply and allow the grill to cool completely.
2. Open and support the existing left-hand cabinet door, then remove it from its factory hinge/mounting points.
3. Position the Weber 64666 replacement door onto the original mounting points and verify that it opens, closes, and aligns properly with the right-hand door.

If the new door does not align correctly, inspect the grill frame and mounting points for damage before attempting to force the door into position.

FAQ Section

Is Weber 64666 the left or right cabinet door?
64666 is the left-hand stainless steel door. Weber's official description is “LHS Door, SS, Genesis 300 series (2022).”

What is the matching right-hand door?
The matching right-hand stainless steel cabinet door is Weber 64667. Weber lists both parts together in compatible GENESIS 300 Series schematics.

Can I replace both stainless steel doors at once?
Yes. Weber also identifies 68734 as the stainless steel door kit for compatible GENESIS 300 Series grills. This is separate from the individual 64666 left and 64667 right doors.

Is Weber 64666 stainless steel?
Yes. Weber specifically uses “SS” in its factory description for 64666, distinguishing it from the black left-hand door, part 64479.

Does Weber 64666 fit older GENESIS II grills?
Do not assume so. Weber specifically identifies 64666 as a GENESIS 300 Series (2022) component. Earlier GENESIS and GENESIS II models can use different doors, hinges, and cabinet configurations.
