What is the upper part of a fridge called?
On the Frigidaire FRT18IL6JW7 top-mount refrigerator, the upper section is the freezer compartment. It is designed to keep foods frozen, and it often houses the ice maker (if your refrigerator is equipped with one). For model-specific features and control settings, use the FRT18IL6JW7 owner's manual.
What the freezer compartment includes
Most top-mount freezer sections commonly include:
- Freezer shelves or a freezer panel for organizing frozen foods
- A freezer temperature control (sometimes shared with fresh food control)
- An ice maker area (optional on some configurations)
- Door bins for smaller frozen items
- Air vents that circulate cold air to the refrigerator section
Freezer vs. refrigerator section (quick comparison)
| Section | Common name | Main purpose | Typical temperature |
|---|---|---|---|
| Upper section | Freezer compartment | Freezes and stores frozen food | 0°F |
| Lower section | Fresh food compartment | Keeps refrigerated foods cold | 37°F |
Why it matters
Knowing the correct name helps when you are ordering parts, following installation steps, or troubleshooting cooling issues. For example, the installation checklist calls out that the freezer door should be level across the top and that the door seals completely to the cabinet on all sides, which directly affects freezer performance.
Helpful tips for better freezer performance
- Keep the freezer door gasket clean so it seals tightly
- Avoid blocking air vents with large boxes or bags
- Set controls and wait about 24 hours before making more adjustments
- Make sure the refrigerator is level and tilted slightly back so doors close fully

What does CF mean on a Frigidaire refrigerator?
On a Frigidaire FRT18IL6JW7 top-mount refrigerator, CF is commonly used as a control or communication fault indicator. It points to the control system not reading or responding correctly, often due to a loose connection, damaged wiring, or a failing control board.
What to check first (quick, safe steps)
- Power reset: Unplug the refrigerator for 5 minutes, then plug it back in.
- Control settings: After any control change, wait 24 hours before making more adjustments (this is normal for these models). See the FRT18IL6JW7 installation guide.
- Temperature basics: Make sure the fresh food and freezer controls are set to a normal range (many Frigidaire models run normally around mid-range settings).
- Door seal and leveling: A door not sealing or a cabinet that is not level can cause temperature swings that trigger control-related symptoms.
- Listen for normal operation: Fans and the compressor should cycle on and off; unusual silence or constant running can help narrow the issue.
If CF comes back: likely causes and what they mean
| Likely cause | What you may notice | Typical fix |
|---|---|---|
| Loose or corroded wire connection | Code appears intermittently, unit may restart | Reseat connectors, inspect harness plugs |
| Damaged wiring harness | Code returns after reset, cooling may be inconsistent | Repair/replace harness (model-specific part lookup) |
| Failing control board or user interface | Code persists, controls act erratically | Replace the failed control component |
Why it matters
A CF-type fault can prevent the refrigerator from regulating temperatures correctly. That can lead to warm fresh food, soft ice, excess frost, or longer run times that stress components like the evaporator fan motor and compressor.

What is the most common problem with a Frigidaire refrigerator?
The most common problem we see on Frigidaire refrigerators like model FRT18IL6JW7 is poor cooling (warm fresh-food section, weak freezer performance, or temperature swings). The most frequent causes are restricted airflow from dirty coils, a failing evaporator fan, or air leaks at the door gasket; setup and control settings also matter (see the FRT18IL6JW7 installation guide).
Quick checks that fix many “not cold enough” complaints
- Confirm the refrigerator is level and tilted slightly front-to-back (about 1/4 inch) so doors close and seal well.
- Make sure the door seals completely on all sides; look for gaps, rips, or a door that pops open.
- Set controls to a normal range and wait 24 hours after changes before adjusting again.
- Verify vents inside the cabinet are not blocked by food packages.
- Clean dust from the condenser area (unplug first).
Common symptoms and the most likely causes
| Symptom | Most likely cause | What to do first |
|---|---|---|
| Fresh food warm, freezer OK | Airflow issue in fresh-food section, door not sealing | Check door closure, clear vents, confirm leveling |
| Freezer warm, little airflow | Evaporator fan not moving air | Listen for fan; inspect for ice buildup |
| Frost/ice buildup on back wall | Defrost system problem | Check for heavy frost; plan defrost diagnosis |
| Runs a lot, temps drift | Dirty condenser, gasket leak | Clean coils; inspect gasket |
Parts that commonly relate to these problems on FRT18IL6JW7
If your checks point to a specific failure, these model-matched parts are commonly involved:
- Refrigerator evaporator fan motor 241854301 (moves cold air through the freezer and into the fresh-food section)
- Refrigerator defrost heater 242044008 (melts frost off the evaporator during defrost)
- Refrigerator defrost bi-metal thermostat 5303918202 (helps control defrost heating)
- Refrigerator gasket 242193213 (prevents warm air leaks that cause poor cooling and frost)
Why it matters
Cooling problems usually start as an airflow or sealing issue; fixing those early helps prevent heavy frost buildup, food spoilage, and excessive run time that can shorten compressor life.

Why is my Frigidaire top mount freezer not freezing?
If your Frigidaire FRT18IL6JW7 top-mount freezer isn’t freezing, the most common causes are incorrect control settings, poor airflow from dirty condenser coils, a failed evaporator fan, or warm air leaking past the door gasket. Start with the control settings and basic airflow checks in the FRT18IL6JW7 installation guide.
Quick checks that fix many “not freezing” complaints
- Confirm the freezer control was changed recently; after any adjustment, wait 24 hours before changing it again.
- Make sure the freezer door closes fully and the gasket seals on all sides.
- Verify the refrigerator is level and tilted slightly front to back (about 1/4 inch); poor leveling can affect door sealing.
- Check for blocked vents or overpacked shelves that prevent cold air circulation.
- Clean dust from the condenser coil area and make sure the condenser fan area is not obstructed.
What to test next (most likely parts and symptoms)
| Symptom | What it usually points to | Helpful part for this model |
|---|---|---|
| Freezer warm, fridge also warm, compressor runs a lot | Dirty coils, airflow issue, sealed system concern | (Clean first; parts vary) |
| Freezer warm, you don’t hear/feel air moving inside | Evaporator fan problem | Refrigerator evaporator fan motor 241854301 |
| Heavy frost on freezer back wall, cooling fades over days | Defrost system problem | Refrigerator defrost heater 242044008 or refrigerator defrost bi-metal thermostat 5303918202 |
| Frost pattern looks uneven, weak cooling even with good airflow | Refrigerant restriction or compressor issue | Service-level diagnosis |
Why it matters
A freezer that can’t hold temperature forces the compressor to run longer, which can spoil food and accelerate wear on cooling components. Fixing airflow and sealing issues early often prevents bigger repairs.
Safety and service notes
- Unplug the refrigerator before accessing internal panels, wiring, or fan blades.
- If you suspect a sealed system or compressor issue, we recommend professional service.
