KitchenAid KRFC300ESS12 bottom-mount refrigerator Parts

Bottom-mount refrigerators like the KitchenAid KRFC300ESS12 put the fresh-food section at eye and waist level, so you reach everyday items with less bending. The freezer stays below, which works well when you access refrigerated foods more often than frozen foods.

Key advantages you will notice day to day

• Easier access to fresh food: shelves, deli drawers, and produce are higher up.
• Less bending and squatting: you are not constantly reaching down for milk, leftovers, or produce.
• Better organization for fresh items: the main compartment is typically wider and easier to scan.
• Freezer storage stays separate: frozen items are contained below, reducing cold-air loss in the fresh-food area during quick grabs.
• Good fit for meal-prep households: frequent refrigerator use feels more convenient.

Bottom-mount vs top-freezer: quick comparison

Feature	Bottom-mount refrigerator	Top-freezer refrigerator
Fresh-food access	Higher, easier	Lower, more bending
Freezer access	Lower, more bending	Higher, easier
Best for	Heavy fresh-food use	Heavy freezer use
Typical layout	Drawer-style freezer	Swing-door freezer

Why it matters

Most households open the refrigerator section far more than the freezer. With a bottom-mount design, the items you use most are positioned where your body naturally reaches, which improves comfort and makes it easier to keep food visible and organized.

A bottom-mount refrigerator like the KitchenAid KRFC300ESS12 is better when you want fresh-food items at eye level and more flexible refrigerator organization; a top-mount is better when you want a simpler layout and typically lower purchase and repair costs. “Better” depends on how you shop and how often you use the freezer.

Quick comparison

Feature	Top-mount (freezer on top)	Bottom-mount (freezer on bottom)
Everyday access	Freezer is easiest to reach	Refrigerator section is easiest to reach
Organization	Usually simpler shelving	Often more bins, drawers, and zones
Freezer storage	Wide shelf space	Pull-out baskets, easier to sort
Typical cost	Usually lower	Usually higher
Typical efficiency	Often slightly better	Often slightly lower

Choose a bottom-mount if you want

• Fresh-food shelves at a more comfortable height (less bending)
• Better day-to-day organization for produce, deli items, and beverages
• A pull-out freezer basket system that helps prevent “lost” items
• A layout that fits how most households use a fridge (refrigerator more than freezer)

Choose a top-mount if you want

• A straightforward design with fewer moving parts and features
• A freezer that is used frequently and needs to be easy to reach
• A fridge that is often more budget-friendly to buy and maintain

Why it matters

Bottom-mount designs prioritize the refrigerator compartment, which is where most people spend the most time. If you are comparing layouts because of door sealing, temperature swings, or cooling performance, we recommend starting with the basics: confirm the doors close squarely and the seals are clean and pliable.

For your KitchenAid KRFC300ESS12 bottom-mount refrigerator, we recommend ordering replacement parts by matching your model number first, then selecting the exact part from the KRFC300ESS12 parts list so you get the correct fit and electrical compatibility.

Fast way to find the right part

• Confirm the model number on the rating label: KRFC300ESS12
• Identify the symptom or the part name (for example: door not sealing, warm fridge, fan noise)
• Choose the exact replacement from the parts list for your model
• Match by part ID when possible (most accurate)
• Order the part and compare it to the original before installing

Common KRFC300ESS12 parts customers replace

If you are troubleshooting a specific issue, these model-matched parts are commonly involved:

• Temperature sensing issues: refrigerator thermistor W10316760
• Door not closing or interior light problems: refrigerator door switch W11396033
• Warm refrigerator section or airflow noise: refrigerator evaporator motor W11024089 and refrigerator evaporator fan blade WP2169142
• Airflow imbalance between compartments: refrigerator electronic damper WPW10594329
• Door seal leaks: whirlpool refrigerator door gasket (gray) W10443320 or whirlpool refrigerator door gasket, right (gray) W10830162

Part matching tips (what to compare)

What you have	What to match when ordering	Why it helps
Model number	KRFC300ESS12	Filters the correct parts list
Old part label	Part ID (example: WPW10317076)	Prevents ordering a look-alike
Symptom	Part function (thermistor, damper, fan motor)	Narrows the right section
Door seal	Left vs right, color	Avoids fit and sealing issues

Why it matters

Refrigerators often use similar-looking parts across multiple KitchenAid and Whirlpool-built models. Using the KRFC300ESS12 parts list and matching by part ID helps prevent returns and fixes issues like temperature swings, frost buildup, and door leaks faster.

The most common issues we see with KitchenAid refrigerators like model KRFC300ESS12 are ice maker problems and temperature control complaints (warm fridge, freezing produce, or wide temperature swings). These often trace back to airflow, sensing, or sealing problems rather than the sealed refrigeration system.

Most common symptoms (and what they usually point to)

• Ice maker slow or not making ice: water supply restriction, air in the line, or a failing ice maker assembly
• Fresh food section too warm: weak evaporator fan, iced-up airflow path, or a damper that is stuck
• Freezer OK but fridge warm: damper issue or evaporator fan issue
• Frost buildup or moisture around doors: door gasket not sealing or doors out of alignment
• Lights or dispenser behavior odd when door opens/closes: door switch problem
• Noisy operation: fan blade rubbing ice or a worn fan motor

Quick checks we recommend first (10 to 20 minutes)

1. Confirm settings: set refrigerator near 37°F and freezer near 0°F.
2. Check door seal: close a dollar bill in the gasket; it should resist being pulled out.
3. Listen for the evaporator fan: it should run when the compressor is running (door closed).
4. Look for airflow: weak airflow from the refrigerator vents often means a fan or damper issue.
5. Inspect for frost: heavy frost on the back freezer panel often indicates a defrost or airflow problem.

Parts that commonly solve these problems on KRFC300ESS12

Symptom	Common part to check	What it affects
Temperature swings, odd readings	Refrigerator thermistor W10316760	Temperature sensing and control decisions
Fridge warm, freezer OK	Refrigerator electronic damper WPW10594329	Airflow from freezer to fresh food section
Warm temps, noise, weak airflow	Refrigerator evaporator motor W11024089	Circulates cold air across the evaporator
Door not sealing, moisture/frost	Whirlpool refrigerator door gasket (gray) W10443320	Prevents warm air leaks
Ice maker not working	Ice maker as W11692144	Ice production and harvest

Why it matters

Ice maker and temperature complaints usually come from airflow, sensing, or sealing. Fixing those early helps prevent food spoilage, reduces frost buildup, and keeps the compressor from running excessively.

KitchenAid bottom-mount refrigerator model KRFC300ESS12 measures 35 11/16 in wide, 70 1/8 in high, and 34 5/8 in deep (overall depth with handles). For a cabinet opening, we also plan for door swing and ventilation clearance.

Dimensions to use for planning

Use these common spec points when measuring your space:

Measurement point	KRFC300ESS12 dimension
Width	35 11/16 in
Height (to top of hinge)	70 1/8 in
Depth (with handles)	34 5/8 in

How we recommend measuring your space

Measure the opening and the path into the kitchen before delivery or installation:

• Opening width: side wall to side wall at the narrowest point
• Opening height: floor to the lowest overhead cabinet or trim
• Depth: back wall to the front edge of surrounding cabinets
• Door swing: confirm the French doors can open without hitting a wall
• Ventilation: leave space behind and above for airflow

Why it matters

Accurate dimensions prevent fit problems such as doors that cannot open fully, a freezer drawer that rubs, or a refrigerator that sticks out farther than expected.

Related fit and sealing parts

If you are checking dimensions because the doors are rubbing or not sealing after leveling, inspect the door gasket and alignment:

• Whirlpool refrigerator door gasket, right (gray) W10830162
• Whirlpool refrigerator door gasket (gray) W10443320
