What is the most common problem with a Frigidaire refrigerator?
Cooling problems are the most common issue we see on Frigidaire refrigerators like model GLRT13TEK1. In many cases, the root cause is restricted airflow or heat removal (dirty condenser area, blocked vents, or a door that is not sealing), which makes temperatures drift and food spoil faster.
Quick checks that fix many “not cold enough” complaints
- Confirm the temperature controls are not set to 0 (that stops cooling). See the recommended settings in the GLRT13TEK1 owner's manual.
- Allow 24 hours after changing settings for temperatures to stabilize.
- Make sure the refrigerator is level so the doors close tightly.
- Do not overcrowd shelves; keep air vents clear so cold air can circulate.
- Clean the condenser area periodically; it helps the refrigerator run more efficiently.
Other common Frigidaire refrigerator issues (and what they usually point to)
| Symptom | Most common cause | What to check first |
|---|---|---|
| Runs a lot, weak cooling | Poor heat removal or airflow | Condenser cleaning, vent blockage, door closing |
| Warm fridge, freezer OK | Airflow problem between sections | Frost buildup, evaporator fan airflow |
| Noisy or vibrating | Cabinet not level or weak floor | Leveling, floor stability |
| Odors | Spills or uncovered food | Clean interior, cover foods |
| Light not working | Bulb or stuck switch | Replace bulb, press light switch |
If the interior light is out, replacing the refrigerator light bulb 316538904 is a common, quick repair.
Why it matters
A refrigerator that cannot move heat out efficiently or cannot circulate cold air will run longer, waste energy, and struggle to hold safe food temperatures. Basic airflow, leveling, and cleaning checks solve a large share of “Frigidaire refrigerator not cooling” calls.

What is a top mount refrigerator?
A top-mount refrigerator is a classic refrigerator layout where the freezer compartment is on top and the fresh-food (refrigerator) compartment is below. Your Frigidaire GLRT13TEK1 uses this design to keep everyday refrigerated items at a comfortable reach while still providing a full-width freezer above.
How a top-mount layout is organized
In a top-mount refrigerator like the GLRT13TEK1, you typically get:
- A freezer section on top for frozen foods and ice storage
- A fresh-food section below for produce, dairy, and beverages
- Door bins and shelves for quick access to frequently used items
- Adjustable storage features (varies by configuration)
For a full overview of features, controls, and storage options, use the GLRT13TEK1 owner's manual.
Why many people choose top-mount refrigerators
Top-mount models are popular because they balance capacity, simplicity, and easy service access.
| Feature | Top-mount refrigerator | What it means for daily use |
|---|---|---|
| Freezer location | Top | Frozen items are at eye level |
| Fresh-food location | Bottom | Most-used items are slightly lower |
| Typical design | Traditional, straightforward | Fewer complex components than some styles |
| Door swing options | Often reversible | Helps fit different kitchen layouts |
Installation and space basics (important for performance)
Proper airflow and leveling help any top-mount refrigerator cool correctly and avoid vibration noise.
- Allow about 3/8 inch clearance at the sides and top
- Allow about 1 inch clearance at the back
- Keep the toe grille unblocked for airflow
- Level the cabinet so it sits solidly on all corners and tilts slightly back
Those setup details are covered in the GLRT13TEK1 installation guide.
Why it matters
Knowing you have a top-mount refrigerator helps when you are planning kitchen clearances, reversing door swing, organizing food zones, and troubleshooting cooling issues (freezer cold but fresh-food warm often points to airflow or fan problems).

What is the upper part of a fridge called?
On a Frigidaire GLRT13TEK1 top-mount refrigerator, the upper section is typically called the freezer compartment (or simply the freezer). It’s the coldest area of the appliance and is designed to keep foods frozen while supporting overall temperature control.
What you’ll find in the upper (freezer) compartment
Common freezer-area features on top-mount refrigerators include:
- Freezer shelves or racks for frozen food storage
- Door shelves for smaller items (best for stable, less temperature-sensitive foods)
- Cold-air circulation paths that help freeze food quickly
- A door gasket that seals the compartment to prevent warm air leaks
- Space for ice trays or an optional ice maker (if equipped)
Freezer vs. refrigerator section: quick comparison
| Section | Primary job | Typical temperature target | Best for |
|---|---|---|---|
| Freezer (upper) | Freeze and store long-term | 0°F | Meat, frozen meals, ice, long-term storage |
| Fresh food (lower) | Keep food cold, not frozen | 37°F to 40°F | Produce, dairy, leftovers, drinks |
Why it matters
Knowing the correct name helps when you’re looking up parts, organizing food for better cooling, or following setup and care instructions. For example, many top-mount models cool the fresh-food section by moving cold air from the freezer, so keeping vents clear supports steady temperatures.
Tips for better freezer performance
We recommend these practical habits for most top-mount refrigerators:
- Leave space between packages so cold air can circulate
- Avoid overloading the freezer door with hard-to-freeze items (like ice cream)
- Keep the refrigerator level so doors close tightly
- Maintain proper installation clearances for airflow
- Follow the temperature settings and use guidelines in the GLRT13TEK1 owner’s manual

Why is my Frigidaire top mount freezer not freezing?
If your Frigidaire GLRT13TEK1 top-mount freezer is not freezing, the most common causes are an incorrect temperature setting, poor airflow from overpacking, dirty condenser area, or a defrost-system or fan issue that prevents cold air from circulating. Use the GLRT13TEK1 owner's manual temperature targets to guide your checks.
Quick checks that fix many “not freezing” complaints
- Confirm the freezer is set to 0°F or lower (recommended target for this model family).
- Make sure the freezer is at least 2/3 full for best efficiency, but not packed tight.
- Leave space between packages so cold air can circulate.
- Avoid loading a lot of warm food at once; it can temporarily raise freezer temperature.
- Verify the freezer door closes fully and stays shut.
Airflow and fan symptoms to watch for
A top-mount refrigerator cools by moving air; if airflow is blocked or the fan is failing, the freezer warms up.
Common signs of an airflow problem
- Freezer is warm but you hear the refrigerator running often
- Frost buildup on the back wall of the freezer
- Fresh food section temperatures swing (too warm or uneven)
If you suspect a fan issue, our how to fix your evaporator cooling fan guide walks through the typical checks.
Defrost system problems (frost buildup)
If the evaporator coils ice over, airflow drops and the freezer stops freezing well. On this model, a failed defrost thermostat or heater is a common repair path.
| What you see | Likely direction | What to do next |
|---|---|---|
| Heavy frost/ice on freezer back wall | Defrost system not clearing frost | Defrost fully, then troubleshoot heater/thermostat |
| No frost, but warm temps | Airflow, sealed system, or condenser-side issue | Check fan operation and condenser area |
If you find defrost-related symptoms, the refrigerator defrost bi-metal thermostat 5303918202 is one of the model-matched parts commonly involved.
Why it matters
Keeping the freezer at 0°F or lower protects food quality and safety, and proper loading (space between items, not overloading with warm food) helps the GLRT13TEK1 freeze faster and run more efficiently.
