Weber 64540 Propane Tank Scale Indicator for GENESIS 300 & 400 Series Gas Grills – 2022 & Newer

What Problem This Part Solves

The tank scale indicator allows the user to quickly estimate how much propane remains in the cylinder without removing the tank from the grill.

Replacing Weber 64540 can correct:

• Missing propane level indicator
• Broken or physically damaged indicator
• Indicator that has become difficult to read
• Damage caused while installing or removing the propane cylinder
• Restoration of a used GENESIS grill with missing tank-scale components
• Damaged indicator while the underlying tank scale remains functional

If the indicator does not move correctly after replacement, inspect the 64539 tank scale assembly and its mounting system.

Weber 64539 vs. 64540

These two parts work together but are different components:

• 64539 – Tank Scale Assembly
• 64540 – Tank Scale Indicator

Weber lists the two parts separately in its factory schematics.

If the tank scale mechanism itself is damaged, replacing only 64540 may not correct the problem. Inspect the 64539 tank scale assembly as well.

Important: LP Models Only

The tank scale is used to monitor the weight of a removable propane cylinder. Therefore, 64540 is associated with liquid propane GENESIS models, not natural-gas grills connected directly to a household gas supply.

Installation / Use Instructions

1. Turn off the grill and completely close the propane cylinder valve.
2. Remove or support the propane cylinder as necessary to safely access the tank scale and indicator.
3. Replace the damaged 64540 indicator in its factory position and verify that it moves properly with the tank scale assembly before reinstalling the propane cylinder.

After installation, make sure the propane cylinder is properly seated on the tank scale so the indicator can accurately respond to changes in cylinder weight.

FAQ Section

What is Weber 64540?
Weber 64540 is the genuine tank scale indicator used on select 2022+ GENESIS liquid propane grills. Weber lists it directly alongside the 64539 Tank Scale Assembly.

What does the Weber 64540 indicator do?
It provides the visual portion of the propane tank scale system, helping the user estimate the amount of fuel remaining in the LP cylinder based on its weight.

Does Weber 64540 include the complete tank scale?
No. Weber lists 64539 as the Tank Scale Assembly and 64540 as the Tank Scale Indicator, so they are separate replacement components.

Does Weber 64540 fit both GENESIS 300 and 400 Series grills?
Yes, on compatible LP models. Weber lists 64540 on three-burner GENESIS models such as the E-325s as well as four-burner models such as the S-435.

Does Weber 64540 fit natural-gas GENESIS grills?
No practical application exists for it on a natural-gas grill because the tank-scale system is designed to monitor a removable liquid-propane cylinder.
