Did you know that many appliances bearing the same name are produced
by different manufacturers? For example, a lot of Kenmore
dishwashers are made by Whirlpool and Frigidaire, while
certain Maytag washers were produced by Samsung.
Service and repair manuals often refer to the
original base model before it was rebranded.

Symptoms, Checks and Suggested Solutions
Dryer Drum Capacity as per Manufacturer Specifications (in cubic feet):
The manufacturers began using cubic feet capacity numbers only recently.
Previously, they used relative terms such as "Large" or "Extra Capacity" or laundry weight (e.g. "16 lbs per load")
which did not take into account different fabric weight and volume. Even dryers available today do not have capacity
written in the manual because the same manual
can be used across multiple models. Once the model is no longer sold, the sales literature is discarded
and capacity information often lost.
Analyzing dryers and their components, searching through old technical information and sales literature, and
determining their capacity is a labor intensive and time-consuming task and we are far from finished.
A small charge will help us continue our research.
Consider this: if you were to spend more than few minutes looking for dryer capacity on the internet, you
would be earning LESS than minimum wage.
Calculate Dryer Drum capacity
This is a geometric method to calculate drum capacity based on the cylinder volume formula.
Unfortunately, the value could be as much as 25% off from the manufacturer stated capacity.
Why? Because a drum is not exactly a cylinder. The edge where bottom connected to the wall
is not at 90 degree angle but smooth and rounded. The end of the drum is not clearly marked and
the back is not always flat. Finally, there are baffles inside the drum used for tumbling clothes.
This method can be used as a crude estimate but we do not recommend using it for comparisson
when shopping for a new dryer.
To determine your dryer drum capacity please take two simple measurements:
1. Use the ruler to measure the depth of the drum (indicated by the red line on the diagram)
2. Now find the distance accross the drum, the diameter (the green line on the diagram).
Do not confuse the size of the the door opening with the size of the drum.
In this case make the measurements INSIDE the drum.
Dryer Drum Depth: in. Dryer Drum Diameter: in.

Make sure to use the manufacturer's part number when ordering a replacement.
