Which is better, top mount or bottom mount refrigerator?
A top-mount refrigerator like the Frigidaire FPUI2188PF1 is usually the better choice if you want lower upfront cost, strong reliability, and good energy efficiency. A bottom-mount is usually better if you want fresh-food items at eye level and easier access to the refrigerator section.
Quick comparison (what changes day to day)
| Feature | Top-mount (freezer on top) | Bottom-mount (freezer on bottom) |
|---|---|---|
| Most-used section | Refrigerator is lower | Refrigerator is higher |
| Typical price | Lower | Higher |
| Freezer access | Easier for frequent freezer use | Easier for large freezer drawers |
| Organization | Simple shelves and bins | Often more drawer-based storage |
How to choose for your kitchen and habits
We recommend deciding based on how you actually use the refrigerator:
- If you cook daily and reach for fresh foods often, bottom-mount usually feels more convenient.
- If you use the freezer a lot (frozen meals, bulk meat), top-mount can be more practical.
- If you want fewer complex parts and simpler service access, top-mount designs are typically straightforward.
- If you are tight on budget, top-mount models often deliver the best value.
- If bending is a concern, bottom-mount reduces how often you bend for the refrigerator section.
Why it matters
“Better” depends on ergonomics and storage style. The layout affects how often you bend, how you organize groceries, and how quickly you notice temperature issues (for example, warm fresh-food temps can be linked to airflow problems).
Related maintenance tip (applies to both styles)
If you ever notice weak cooling in either compartment, checking the evaporator fan system is a common next step. For this model, parts that relate to airflow include the refrigerator evaporator motor 242077705 and refrigerator evaporator fan blade 5308000010.

What is the upper part of a fridge called?
On the Frigidaire FPUI2188PF1 top-mount refrigerator, the upper section is typically called the freezer compartment. It is the coldest area of the appliance and is designed to keep food frozen and support ice-making features when equipped.
What you will find in the upper (freezer) section
- Freezer shelves or bins for frozen food storage
- A temperature control setting that affects freezer performance (and often fresh-food temps too)
- Air vents that circulate cold air down into the refrigerator section
- Ice-making components if your unit has an ice maker installed
Common terms people use (and what they mean)
| Term | What it usually refers to | Where it is |
|---|---|---|
| Freezer compartment | The upper frozen-food area | Top section on a top-mount refrigerator |
| Freezer door | The door that seals the freezer | Upper door |
| Evaporator area | The cooling coil and fan zone that makes cold air | Behind the rear freezer panel |
| Ice maker | The assembly that freezes and harvests ice | Inside the freezer (if equipped) |
When the “upper part” is not cooling right
If the freezer is warm, the refrigerator section will usually warm up too. These checks solve many cooling complaints:
- Confirm the freezer door closes fully and the gasket seals all the way around
- Make sure vents are not blocked by food packages
- Listen for the evaporator fan running when the compressor is on
- Look for heavy frost on the back freezer wall (a defrost problem clue)
- Verify the temperature setting was not accidentally changed
If you are troubleshooting ice production specifically, our common refrigerator ice maker problems and solutions guide helps narrow down the cause.
Why it matters
On a top-mount design like the FPUI2188PF1, the freezer is the “engine room” for cooling. Cold air is produced in the freezer and then circulated to the fresh-food compartment, so freezer airflow and sealing directly affect overall temperatures.

Do all Frigidaire refrigerators use the same water filter?
No. Frigidaire refrigerators (including model FPUI2188PF1) do not all use the same water filter; the correct filter depends on the exact refrigerator model and its water system design. Using the wrong filter can reduce water flow, cause leaks, or prevent proper filtration.
How to choose the right filter for FPUI2188PF1
We recommend matching by model number first, then confirming the filter style and connection type.
- Confirm the refrigerator model number on the inside wall label: FPUI2188PF1
- Check whether your unit uses an internal cartridge filter, an inline filter, or no filter
- Compare the old filter’s shape and end connections (quarter-turn, push-in, etc.)
- Replace on schedule (most refrigerator water filters are changed about every 6 months)
- If you have low flow after replacement, purge air and flush several gallons
If your refrigerator uses an inline-style filter/drier in the sealed system, that is a different component than a drinking-water filter. For this model, an example sealed-system component is the refrigerator filter dryer 5303305677.
Quick comparison: water filter vs filter dryer
| Item | What it does | Where it’s used | When it’s replaced |
|---|---|---|---|
| Water filter (drinking water) | Improves taste and reduces contaminants | In the water line or inside the fresh food section | Routine maintenance (often about every 6 months) |
| Filter dryer (sealed system) | Removes moisture/contaminants from refrigerant | In the refrigeration sealed system | During sealed-system service |
Why it matters
A matched filter protects your Frigidaire refrigerator’s water system performance (flow rate, ice maker fill, and leak prevention) and helps ensure you get the filtration results you expect.

What does EF stand for on a Frigidaire refrigerator?
On the Frigidaire FPUI2188PF1 top-mount refrigerator, EF (often shown as SY EF or 5Y EF) points to a problem in the evaporator fan circuit. In most cases, the issue is the evaporator fan motor, fan wiring, or airflow restrictions that keep the fan from running correctly.
What to check first (safe, quick checks)
- Make sure food packages are not blocking the air vents in the freezer.
- Listen for the evaporator fan: it should run when the compressor is running and the freezer door switch is pressed.
- Look for heavy frost on the back freezer panel (a defrost problem can stop airflow and trigger fan-related symptoms).
- Check that the freezer door closes tightly and the gasket is sealing evenly.
- Power reset: unplug the refrigerator for 5 minutes, then restore power and recheck.
Parts commonly involved
If the EF code keeps returning after airflow checks, these model-compatible parts are common suspects:
- Refrigerator evaporator motor 242077705 (fan motor not running or noisy)
- Refrigerator evaporator fan blade 5308000010 (blade stripped, cracked, or rubbing)
- Refrigerator defrost bi-metal thermostat 5303918202 (defrost issue leading to frost buildup and poor airflow)
Symptom-to-likely-cause guide
| What you notice | Most likely cause | What we recommend |
|---|---|---|
| Freezer cold but fresh food warm | Weak or stopped evaporator fan | Inspect fan motor and blade |
| Loud buzzing or scraping in freezer | Fan blade hitting ice or shroud | Clear ice, check blade condition |
| Heavy frost on freezer back wall | Defrost system problem | Check for defrost-related failure |
| EF code comes and goes | Intermittent fan wiring/connection | Inspect harness and connectors |
Why it matters
The evaporator fan moves cold air from the freezer through the refrigerator. When the fan circuit has a fault, temperatures drift, frost can build up, and food can warm up even if the compressor is running.
