KitchenAid KFFS20EYMS01 refrigerator Parts

Yes. KitchenAid makes 33-inch-wide refrigerators, including full-depth bottom-mount models. Your KitchenAid KFFS20EYMS01 is a bottom-mount refrigerator, and 33-inch width is a common size in this style when you need a narrower fit than many 36-inch units.

How to confirm a 33-inch model will fit

We recommend checking three measurements before you buy or swap refrigerators:

• Cabinet opening width (measure wall-to-wall at the front and back)
• Door swing clearance (space needed for doors and handles)
• Depth clearance (space behind for water line and airflow)

Typical sizing guide (what to expect)

Refrigerator type	Common widths	Notes
Bottom-mount (full depth)	30 to 33 inches	Often the best choice for tighter kitchens
French door (full depth)	33 to 36 inches	33-inch versions exist, but 36 is more common
Counter-depth styles	33 to 36 inches	Shallower depth, sometimes needs more rear clearance

Why it matters

A “33-inch refrigerator” is usually designed to fit a 33-inch cabinet opening, but real-world fit depends on hinges, handles, and leveling. Confirming clearances up front prevents door interference, poor airflow, and installation headaches.

Parts note for KFFS20EYMS01 owners

If you are keeping your current refrigerator running instead of replacing it, common maintenance items for KFFS20EYMS01 include the water filter and air filter. For example, you can match your filter by using the model-specific part listing such as the refrigerator filter EDR1RXD1.

To remove the bottom grill (toe kick) on your KitchenAid refrigerator model KFFS20EYMS01, grasp the grill at the ends and pull it straight forward to release the retaining clips. Reinstall by aligning it with the lower frame and snapping it back into place.

Quick steps

• Unplug the refrigerator or switch off power at the breaker (recommended).
• Open both fresh food doors for better access.
• Grip the toe kick near the left and right ends (not in the center).
• Pull straight out toward you; use steady, even pressure.
• If it resists, work one end loose, then the other.
• To reinstall, line up the tabs/clips with the slots and press until it snaps in.

If the grill will not come off

Most toe kicks are held by spring clips or tabs; forcing it downward can crack the plastic.

• Check for hidden screws (some installations use screws at the corners).
• Look for a water line or wiring routed behind the grill; move it gently aside.
• Use a plastic putty knife to help pop a stubborn clip (avoid metal tools that scratch).
• If the grill is warped, warm it slightly with room-temperature air so it flexes instead of snapping.

What you can do while it is off

Task	Why it helps	How often
Vacuum condenser area	Improves cooling and efficiency	Every 6 to 12 months
Inspect for leaks	Catches water issues early	Any time you see puddles
Check door closing	Helps prevent frost and warm temps	Monthly

Why it matters

A properly seated toe kick helps protect components at the bottom of the refrigerator and keeps airflow where it belongs for stable temperatures.

Frost buildup in the bottom freezer on your KitchenAid KFFS20EYMS01 almost always happens because warm, humid air is getting into the freezer compartment. The most common causes are a door that is not sealing or closing fully, frequent door openings, or a blocked air path that keeps moisture from clearing out.

Quick checks that fix most frosting

• Make sure the freezer door closes firmly and stays closed (no bounce-back).
• Check for packages, ice bins, or baskets preventing the door from shutting.
• Inspect the door gasket for gaps, tears, or hardened sections; clean it with mild soap and warm water, then dry.
• Look for frost only along the door edge (points to a sealing issue) versus heavy frost on the back wall (often airflow or defrost related).
• Confirm the freezer is not overpacked; leave space for air to circulate.

What to look for based on where the frost is

Frost pattern	Most likely cause	What to do first
Frost around the door opening	Door not sealing, gasket dirty, door misaligned	Clean gasket, remove obstructions, check door closing
Heavy frost on back wall/vents	Airflow restriction or defrost system issue	Clear vents, reduce packing, then monitor 24 to 48 hours
Frost plus warm temps/soft ice cream	Evaporator fan not moving air	Check for fan noise; use how to fix your evaporator cooling fan

Parts that commonly relate to frosting symptoms

If you confirm the door is sealing and the freezer still frosts up quickly, these parts are often involved in airflow and temperature control:

• Evaporator fan motor: refrigerator evaporator motor WPW10464673
• Temperature sensing: refrigerator thermistor WPW10383615
• Door closing hardware (if the door does not self-close smoothly): refrigerator door cam WPW10470155

Why it matters

Excess frost blocks airflow, which makes the refrigerator run longer, causes temperature swings, and can lead to poor ice production and food quality issues.

For KitchenAid refrigerators like model KFFS20EYMS01, the most common issues we see are ice maker and water dispensing problems and cooling/temperature complaints (warm fridge, freezer OK, or inconsistent temps). These often trace back to airflow, filtration, or water-supply components.

Most common symptoms (and what they usually point to)

• Ice maker not making ice or slow ice: restricted water flow, air in the line, or an ice maker issue
• Water tastes bad or flow is weak: clogged water filter
• Fridge warm, freezer cold: evaporator fan or airflow problem
• Frost buildup or water puddles: defrost drain or door sealing issue
• Clicking/humming and poor cooling: compressor start components or sealed-system stress

Quick checks we recommend first

1. Confirm temperatures: set refrigerator to about 37°F and freezer to about 0°F.
2. Check airflow: make sure vents are not blocked by food packages.
3. Rule out filtration restriction: replace the water filter if it is older than 6 months.
4. Listen for the evaporator fan: you should typically hear it running when the compressor is on.
5. Inspect door sealing: gaps or a torn gasket can cause moisture, frost, and temperature swings.

Parts that commonly solve these problems on KFFS20EYMS01

Problem area	What fails most often	Example part for this model
Water and ice	Clogged filter	Refrigerator filter EDR1RXD1
Water and ice	Weak/failed valve	Refrigerator water inlet valve WPW10238100
Cooling/airflow	Fan not moving air	Refrigerator evaporator motor WPW10464673
Temperature sensing	Sensor out of range	Refrigerator thermistor WPW10383615
Ice production	Ice maker failure	Refrigerator ice maker assembly 4317943

Why it matters

Ice maker and cooling problems can look similar (no ice, soft ice, warm temps), but the fix changes depending on whether the root cause is water supply, airflow, or temperature sensing. Starting with the simple checks above prevents unnecessary part replacement.
