What is the upper part of a fridge called?
On the Frigidaire FRT18IL6DBN top-mount refrigerator, the upper section is the freezer compartment. It’s the coldest area of the appliance, designed to keep foods frozen and, on some setups, support an automatic ice maker.
- Freezer shelves or racks for frozen food storage
- Freezer door shelves (best for items that tolerate temperature swings)
- Space for ice trays or an automatic ice maker (if equipped)
- Cold air circulation paths that help freeze food quickly
The freezer works best when air can move around packages and the door stays closed tightly.
- Leave space between packages so cold air can circulate
- Avoid overloading with warm food; it slows freezing and can warm frozen items
- Store hard-to-freeze items (like ice cream) toward the interior, not on the door
- Wrap foods well to prevent freezer burn
| Location | Best for | Avoid for |
|---|---|---|
| Freezer door shelves | Frequently used, sturdy frozen items | Ice cream, juice concentrates, delicate items |
| Freezer interior | Long-term storage, temperature-sensitive foods | Overpacking that blocks airflow |
Knowing the “upper part” is the freezer compartment helps when you’re adjusting temperature controls, organizing food for better airflow, or troubleshooting issues like soft ice cream or slow freezing. For model-specific storage features and recommended settings, use the FRT18IL6DBN owner's manual.

What are the advantages of a top mount fridge?
A top-mount refrigerator like the Frigidaire FRT18IL6DBN puts the freezer on top, which makes frozen foods easier to reach and typically keeps the design simple, efficient, and budget-friendly. It also tends to offer strong fresh-food storage space for its overall footprint.
- Easy access to frozen foods: the freezer is at about eye and chest level.
- Good fresh-food capacity for the size: many top-mounts maximize usable refrigerator shelf space.
- Straightforward layout: fewer complex door mechanisms than some premium styles.
- Often lower operating cost: simpler airflow and fewer features can mean less to maintain.
- Flexible placement: doors can often be reversed to fit your kitchen traffic flow (your manual notes door reversal is possible).
Top-mount models work especially well when you:
- Use the freezer frequently (frozen meals, ice, bulk items)
- Want a traditional layout with familiar shelves, bins, and crispers
- Prefer a simpler refrigerator that is easier to level, place, and service
| Feature | Top-mount refrigerator | Bottom-freezer refrigerator |
|---|---|---|
| Freezer access | Higher, easier to reach | Lower, more bending |
| Fresh-food access | Mid-level | Higher, easier to reach |
| Typical complexity | Lower | Often higher |
| Best for | Frequent freezer use | Frequent fresh-food use |
Proper installation helps any top-mount run efficiently. For the FRT18IL6DBN, our documentation calls out:
- Clearances: about 3/8 inch at the sides and top, and 1 inch at the back
- Leveling: all four corners should rest firmly; use the front rollers or leveling screws as described in the FRT18IL6DBN owner's manual
Choosing the right refrigerator style affects daily convenience, energy use, and how well food stays organized. A top-mount layout is a strong fit when you want easy freezer access and a simple, proven design.

What is the most common problem with a Frigidaire refrigerator?
The most common Frigidaire refrigerator problem is not cooling properly, and on the FRT18IL6DBN that typically traces back to airflow issues (frost buildup), a fan problem, or a temperature control or defrost issue. Start with basic checks from the FRT18IL6DBN owner's manual before replacing parts.
- Refrigerator warm, freezer warm: power issue, control set to OFF, or unit in defrost cycle
- Freezer cold but refrigerator warm: restricted airflow from frost, blocked vents, or evaporator fan issue
- Frost buildup in freezer: defrost system problem (heater, thermostat, timer/control)
- Runs a lot or seems loud: often normal high-efficiency operating sounds, or dirty condenser area
- Ice maker not working (if equipped): wire signal arm position, water supply off, or ice maker issue
- Confirm the temperature control is not set to “O” (OFF).
- Make sure the plug is fully seated; check the breaker or replace the fuse with a 15-amp time-delay fuse.
- If it just stopped cooling, wait 20 minutes; it may be in a defrost cycle.
- Avoid overpacking shelves; overcrowding reduces airflow and cooling performance.
- If you have an ice maker, verify the wire signal arm is down (ON) and the water supply is on.
| Symptom | Likely area | Example part for this model |
|---|---|---|
| Frost buildup, warm fresh food | Defrost system | Refrigerator defrost bi-metal thermostat 5303918202 |
| Warm fresh food, freezer OK | Evaporator airflow | Refrigerator evaporator fan blade 5308000010 |
| Door not sealing, moisture/frost | Door seal | Refrigerator gasket 242193213 |
A refrigerator that is not cooling can lead to food spoilage quickly, and running with poor airflow or low voltage can strain the compressor. Keeping airflow clear and controls set correctly prevents many “not cooling” calls.

Why is my Frigidaire top mount freezer not freezing?
If your Frigidaire FRT18IL6DBN top-mount freezer isn’t freezing, the most common causes are incorrect control settings, blocked airflow, dirty condenser coils, or a fan/defrost problem. Start by setting the freezer to 0°F or lower and making sure air vents are not blocked; then check fans and frost buildup using the FRT18IL6DBN owner's manual.
- Set the freezer control colder in small steps; allow time for temperatures to stabilize.
- Confirm the refrigerator control is not set too warm (it can affect both compartments on some models).
- Make sure food packages are not blocking cold air vents.
- Avoid overcrowding; air must circulate around items.
- Keep the freezer at least 2/3 full for best efficiency (use water jugs if needed).
| What you notice | Most likely cause | What to do next |
|---|---|---|
| Freezer warm and fridge warm | Dirty condenser coils, condenser fan issue, sealed system issue | Clean coils; listen for condenser fan and compressor operation |
| Freezer warm but fridge OK | Evaporator fan not moving air, airflow blockage, defrost issue | Check for fan noise; inspect for heavy frost on back wall |
| Heavy frost/ice on freezer back wall | Defrost system problem | Manually defrost to restore cooling short-term; then troubleshoot defrost components |
| Door won’t seal, frost near door | Door gasket leak | Inspect gasket for gaps/tears and warm-air leaks |
If you find a specific failure, these model-matched parts are often involved:
- Refrigerator defrost bi-metal thermostat 5303918202 (can contribute to defrost failures and frost buildup)
- Refrigerator evaporator fan blade 5308000010 (air movement issues if the fan is damaged or obstructed)
- Refrigerator gasket 242193213 (warm air leaks that reduce freezing performance)
A freezer that runs warm can spoil food quickly, and restricted airflow or dirty coils can also make the compressor run longer and less efficiently. Getting the controls, airflow, and defrost system right restores stable temperatures and helps prevent repeat icing problems.
