How can I tell how many cubic feet my Whirlpool refrigerator is?
For your Whirlpool WRS335FDDM00 side-by-side refrigerator, the most reliable way to confirm cubic feet is to look up the capacity listed for your exact model in the product specifications section of the WRS335FDDM00 owner's manual. If you need a quick estimate, you can calculate interior volume from measurements.
Fast ways to find the capacity
- Check the model and serial label location (inside wall of the refrigerator compartment) to confirm you are using WRS335FDDM00.
- Look for “capacity” or “cu. ft.” in the specifications section of the WRS335FDDM00 owner's manual.
- If you only have exterior dimensions, use them for a rough estimate (interior space is always less because of insulation and components).
How to estimate cubic feet by measuring
- Measure the usable interior of the fresh food compartment (width x height x depth) in inches.
- Do the same for the freezer compartment.
- Add the two volumes together.
- Convert cubic inches to cubic feet:
| What you have | What to do | Result |
|---|---|---|
| Cubic inches | Divide by 1,728 | Cubic feet |
| Cubic feet | Multiply by 1,728 | Cubic inches |
Tip: Remove bins and shelves only if needed to measure accurately; measure the open cavity, not the door bins.
Why it matters
Knowing cubic feet helps us match the right replacement parts and accessories (like shelves, bins, and ice storage) and it also helps when comparing energy use and storage needs across refrigerator sizes.

Does anyone make a 33 inch wide refrigerator?
Yes. Multiple major brands make 33-inch wide refrigerators, and a 33-inch side-by-side is a common fit for kitchens that cannot accommodate a 36-inch unit. If you are matching an existing cutout for Whirlpool model WRS335FDDM00, we recommend confirming the exact cabinet opening and clearance requirements in the WRS335FDDM00 user guide.
What “33-inch wide” means when you shop
Manufacturers list width in whole inches, but the actual cabinet width and required clearance can vary by model.
- Measure the cabinet opening width, height, and depth (not just the old refrigerator)
- Plan for door swing clearance and handle clearance
- Confirm ventilation clearance at the top, sides, and back
- Check water line access if you have an ice maker or water dispenser
- Verify electrical outlet location (grounded 3-prong outlet recommended)
Quick comparison: common refrigerator widths
| Nominal width | Typical fit | What to expect |
|---|---|---|
| 30-inch | Tight spaces, apartments | Less capacity, fewer configurations |
| 33-inch | Smaller kitchens, standard cutouts | Good capacity without needing 36-inch space |
| 36-inch | Larger kitchens | Most options and highest capacity |
Tips if you are replacing a Whirlpool WRS335FDDM00
If your current refrigerator is a Whirlpool WRS335FDDM00 side-by-side, staying near the same width usually reduces installation surprises.
- Allow about 24 hours for cooling after installation before judging temperatures
- Use two or more people to move and position the refrigerator
- Avoid extension cords; use a grounded 3-prong outlet
- If the unit has water, confirm the shutoff valve location and water line routing
Why it matters
A refrigerator that is even slightly too wide, or that lacks door-swing clearance, can prevent proper installation and can lead to doors not sealing correctly, which affects cooling performance and energy use.

What is the most common problem with a Whirlpool refrigerator?
The most common problems we see on a Whirlpool refrigerator like model WRS335FDDM00 are cooling complaints (not cold enough or running a lot) and ice maker or water dispenser issues. Many of these trace back to airflow, normal control settings, or water supply problems outlined in the WRS335FDDM00 owner's manual.
Most common symptoms and what they usually point to
- Refrigerator not cooling well: restricted airflow, dirty condenser area, or a fan issue
- Runs a lot: normal after installation or after door openings; can also happen with warm room temps
- No ice or slow ice: ice maker off, low water pressure, frozen fill tube, or valve problem
- No water at dispenser: clogged filter, air in the line, or inlet valve issue
- Noisy operation: many sounds are normal (buzzing, popping, gurgling, sizzling during defrost)
Quick checks we recommend first (before replacing parts)
- Confirm cooling is turned on and controls are set normally (not “coldest” as a shortcut).
- After a new install or power outage, allow 24 hours for full cooling.
- Make sure doors close fully and vents inside are not blocked by food packages.
- If the unit is not connected to water, turn off the ice maker to prevent valve noise.
- If water or ice is weak, replace the water filter on schedule and purge air from the line.
Common part-related causes on this model
If basic checks do not fix it, these parts are often involved:
| Symptom | Common suspect | Example part for WRS335FDDM00 |
|---|---|---|
| No ice and no water fill sound | Water inlet valve not opening | Refrigerator water inlet valve WPW10179146 |
| Ice maker not cycling or not harvesting | Ice maker assembly issue | Refrigerator ice maker assembly WPW10300022 |
| Frost buildup and warm temps | Defrost system problem | Refrigerator heater WP2323198 |
Why it matters
Cooling and ice maker complaints often share the same root causes: airflow and temperature stability. Fixing the basics first helps prevent unnecessary part replacement and protects food temperatures.
