What is a fridge with freezer on top called?
A fridge with the freezer on top is called a top-freezer refrigerator, also commonly called a top-mount refrigerator. Your Samsung RT21M6213SG is this style, with the freezer compartment above the fresh food compartment and separate doors.
What “top-freezer” (top-mount) means
A top-freezer design is the classic refrigerator layout. It is popular because it is simple, efficient, and typically offers a good balance of freezer space and fresh food space.
Common traits include:
- Freezer compartment located above the refrigerator compartment
- Two side-swing doors (one for freezer, one for fresh food)
- Mechanical or electronic temperature controls
- Air vents between compartments that must stay unblocked for proper cooling
How this matters for using and troubleshooting your RT21M6213SG
Because the freezer is the primary cold source on many top-mount designs, airflow from the freezer into the refrigerator section is critical. If vents are blocked or the unit is overpacked, the fresh food section can warm up even when the freezer seems okay.
Quick checks we recommend:
- Keep food from blocking interior air vents
- Leave at least 2 inches (5 cm) of clearance at the sides and rear for airflow
- Adjust temperature settings gradually (avoid extreme settings in very hot or very cold seasons)
- Confirm doors close and seal fully
Helpful reference
For control features and operating modes (including Freezer Convert and temperature adjustment), use the RT21M6213SG owner's manual.
Typical layout comparison
| Refrigerator style | Freezer location | Common name(s) |
|---|---|---|
| Top-freezer | Top | Top-mount, top-freezer |
| Bottom-freezer | Bottom | Bottom-mount |
| Side-by-side | Left side | Side-by-side |
| French door | Bottom drawer | French door |
Why it matters
Knowing the style helps you pick the right parts and follow the right troubleshooting steps, since cooling airflow, defrost components, and control features vary by refrigerator design.

What are the disadvantages of a top mount fridge?
Top-mount refrigerators like the Samsung RT21M6213SG put the freezer on top and the fresh-food section below, so the main drawbacks are less convenient access to everyday items, fewer organization features than many bottom-freezer designs, and fewer built-in dispenser options on many models. See the RT21M6213SG owner's manual for your exact features and layout.
Common disadvantages (what most owners notice)
- You bend more often: fresh-food items are lower, so you reach down frequently.
- Less flexible organization: many top-mount designs have fewer specialty drawers, split shelves, and wide pantry zones.
- Fewer dispenser configurations: many top-mount models do not include an external water or ice dispenser.
- Freezer access can be awkward: bulky items can be harder to stack and retrieve in a top compartment.
- Temperature swings from overloading: if food blocks vents, cooling performance can suffer.
What to check on your RT21M6213SG to reduce the downsides
The manual guidance for this refrigerator is clear: keep airflow open and allow proper installation clearance.
- Keep food from blocking interior vents (this helps prevent frost around vents and uneven cooling).
- Do not overload shelves or door bins; heavy loading can reduce usability and stability.
- Leave ventilation space around the cabinet; a common guideline is about 2 inches (5 cm) at the rear and sides.
- After moving or installing, let the refrigerator stand about 2 hours before loading food.
Quick comparison: top mount vs bottom freezer
| Feature | Top mount (like RT21M6213SG) | Bottom freezer |
|---|---|---|
| Fresh-food access | Lower, more bending | Eye-level, easier access |
| Organization | Often simpler | Often more zones and drawers |
| Ice/water dispenser | Less common | More common |
| Footprint | Usually compact | Often deeper/taller |
Why it matters
Most “top-mount disadvantages” show up as daily convenience issues, not reliability problems. Good airflow and correct clearances help your Samsung refrigerator cool evenly, reduce frost near vents, and keep temperatures stable.

Is a top mount or bottom mount fridge better?
For most households, a bottom-mount refrigerator is better for everyday convenience because fresh-food items sit at eye level, so you bend less. A top-mount like the Samsung RT21M6213SG is often a better value and can be simpler to live with if you use the freezer frequently.
Quick comparison
- Choose bottom-mount if you want the refrigerator section easiest to reach.
- Choose top-mount if you want a classic layout and quick freezer access.
- Either style works well when it is installed level, with proper clearance and stable power, as described in the RT21M6213SG owner's manual.
| Feature | Top-mount (freezer on top) | Bottom-mount (freezer on bottom) |
|---|---|---|
| Most-used section access | Freezer is easiest | Fresh food is easiest |
| Bending for fridge items | More | Less |
| Freezer organization | Shelves, bins | Often a pull-out drawer |
| Typical cost | Usually lower | Usually higher |
| Common fit/space needs | Similar overall | Similar overall |
How we recommend choosing
- How often you use the freezer: frequent freezer use favors top-mount.
- Back and knee comfort: bottom-mount reduces bending for fresh food.
- Kitchen layout: check door swing and aisle clearance before buying.
- Food habits: lots of produce and drinks favors bottom-mount; lots of frozen foods favors top-mount.
- Maintenance comfort: whichever style you choose, keep airflow clear and the unit level for best cooling performance.
Why it matters
The “better” fridge is the one that matches how you reach for food every day. Layout affects comfort, organization, and how consistently temperatures stay stable when doors open and close.
