Is a top or bottom mount fridge better?
A top-mount refrigerator like the Samsung RT18M6213SG is usually the better pick if you want lower cost, simpler design, and strong energy efficiency. A bottom-mount is usually better if you want fresh-food items at eye level and easier access to refrigerator shelves.
Quick comparison
| Feature | Top-mount (freezer on top) | Bottom-mount (freezer on bottom) |
|---|---|---|
| Everyday access | Freezer is easiest to reach | Fresh-food section is easiest to reach |
| Organization | Typically simpler shelving | Often more drawer and basket storage |
| Energy use | Often slightly lower | Often slightly higher |
| Price and repairs | Often lower cost, fewer complex features | Often higher cost, more complex layouts |
When a top-mount is the better choice
Choose a top-mount if these are your priorities:
- Lower purchase and ownership cost
- Good energy efficiency for the size
- Simple layout with fewer moving parts
- You use the freezer often (it is at eye level)
- You want a straightforward refrigerator for a garage, rental, or secondary kitchen
When a bottom-mount is the better choice
A bottom-mount tends to fit better when:
- You use fresh-food items most and want them at chest or eye level
- You prefer wide refrigerator shelves and crisper access without bending as much
- You like pull-out freezer drawers for organizing frozen foods
Why it matters
The “better” style is the one that matches how you load groceries and how often you open each compartment. If you open the refrigerator door far more than the freezer, a bottom-mount can feel more convenient day to day. If you want efficiency and simplicity, a top-mount like RT18M6213SG is a strong choice.
Setup tip that helps either style
After installation, we follow the guidance in the owner's manual to place the refrigerator on a flat, level surface with reasonable clearance and let it stand for about 2 hours before loading food. That helps cooling performance and door sealing.

What is the top part of a refrigerator called?
On the Samsung RT18M6213SG top-mount refrigerator, the top compartment is the freezer compartment. It’s the section designed to keep food frozen, and it typically houses the freezer shelf and (on some versions) an ice maker.
What you’ll find in the top (freezer) section
In the RT18M6213SG layout, the upper area is the freezer and commonly includes:
- Freezer shelf (storage for frozen foods)
- Freezer guard (door bin area for smaller items)
- Ice maker area (optional auto ice maker or twist ice maker, depending on version)
- Freezer temperature controls (set from the control panel)
For the exact component names and locations used for your version, check the owner's manual.
Quick terminology guide
Here’s how the most common “top section” terms compare:
| Term people use | What it usually means | Where it is on RT18M6213SG |
|---|---|---|
| “Top part” | Freezer compartment | Top compartment |
| “Freezer” | Frozen-food storage area | Top compartment |
| “Control panel” | Temperature and feature buttons | Typically inside the upper area or at the top front (varies by version) |
| “Freezer guard” | Freezer door bin area | Freezer door |
Why it matters
Knowing the correct name helps when you’re ordering parts or troubleshooting cooling issues. For example, if the freezer is cold but the fresh food section is warm, we often focus on airflow parts like the evaporator fan motor or the evaporator cover and fan assembly.
Related parts you may see referenced for cooling and airflow
If you’re diagnosing temperature problems (not just naming the compartment), these model-matched parts are commonly involved:
- Refrigerator evaporator fan motor DA31-00287C (moves cold air through the refrigerator)
- Assembly, cover evap-ref DA97-16256B (evaporator cover and fan area in the fresh food section)
- Refrigerator temperature sensor DA32-00070A (feeds temperature readings to the control)

What is the most common problem with Samsung refrigerators?
The most common Samsung refrigerator problem is a cooling issue: the fridge or freezer runs warm, temperatures swing, or frost builds up and blocks airflow. On the Samsung RT18M6213SG, start with airflow, temperature settings, and basic power and clearance checks in the RT18M6213SG owner's manual.
Common symptoms customers notice
- Fresh food section is warm but the freezer seems colder (or the reverse)
- Frost or ice buildup on the back wall or around the evaporator cover
- Fan noise, rattling, or no fan sound at all
- Food spoils faster than normal
- Water leaks or puddles after heavy frost (often tied to defrost and drainage)
What usually causes “not cooling” complaints
- Airflow restrictions: blocked interior vents or overpacked shelves
- Evaporator fan problems: weak, noisy, or stalled fan; refrigerator evaporator fan motor da31-00334d
- Defrost system failures: frost builds until airflow is choked; refrigerator defrost heater DA47-00460G and refrigerator defrost thermal fuse DA47-00301F
- Temperature sensing/control issues: incorrect readings or poor cycling; refrigerator temperature sensor DA32-00070A and refrigerator electronic control board DA92-00979C
Quick checks before replacing parts
- Confirm the power cord is plugged in firmly.
- Set the temperature colder and allow 24 hours to stabilize.
- Keep at least 2 inches (5 cm) of clearance at the sides and rear.
- Make sure interior air vents are not blocked.
- If it was unplugged, wait at least 5 minutes before plugging it back in.
Symptom to likely area
| What you see | Most likely area |
|---|---|
| Warm temps, little/no airflow | Evaporator fan or frost blockage |
| Heavy frost on back wall | Defrost system |
| Temps seem “wrong” | Sensor or control |
Why it matters
Cooling problems are usually airflow or defrost related; once frost blocks the evaporator, the refrigerator runs longer, warms up in one compartment, and food spoils faster.
