Is top mounted refrigerator better than bottom mounted?
A top-mount refrigerator is usually the better pick if you want the lowest cost and strong energy efficiency, while a bottom-mount (like LG LRBN22511TT) is better if you want fresh-food items at eye level and easier day-to-day access. The “better” choice depends on how you use your refrigerator most.
| Feature | Top-mount (freezer on top) | Bottom-mount (freezer on bottom) |
|---|---|---|
| Most-used section access | Refrigerator section is lower | Refrigerator section is higher (more convenient) |
| Freezer access | Easier (at chest level) | Requires bending or pulling out a drawer |
| Organization | Often simpler, fewer drawers | Often better separation with bins/drawers |
| Typical price | Lower | Higher |
| Energy use (typical) | Often slightly better | Often slightly higher (varies by model) |
- Convenience for daily use: Bottom-mount designs keep the refrigerator compartment (where most people store everyday foods) at a more comfortable height.
- Freezer habits: If you use the freezer constantly, a top-mount can feel easier because you are not bending to reach frozen items.
- Kitchen layout: Bottom-mount units often need more clearance for a pullout freezer drawer.
- Temperature performance: Either style can cool well when airflow is not blocked and the doors seal properly.
On the LRBN22511TT, good performance depends on proper setup and airflow. The manual emphasizes keeping the refrigerator away from heat sources and ensuring air can circulate between compartments. If vents are blocked or the door gasket does not seal, cooling efficiency drops regardless of freezer location. See the LRBN22511TT owner's manual for placement, airflow, and door alignment guidance.
- Keep interior vents clear so cold air can circulate.
- Allow the refrigerator to run a few hours after setup before loading it with food.
- Level the refrigerator so doors close and seal consistently.
- Avoid placing the unit near direct sunlight or heat sources.
- If the doors look uneven, follow the manual’s hinge and alignment steps.

What is the most common problem with an LG refrigerator?
Cooling problems are the most common complaint we see across LG refrigerators, including the LG LRBN22511TT. In many cases, the root cause is a sealed-system or compressor-related issue, but airflow restrictions, defrost problems, and temperature-sensing issues can create similar “not cooling” symptoms.
- Confirm the temperature settings and give the unit 24 hours to stabilize after any change.
- Make sure doors fully close and nothing is propping them open.
- Listen for normal operating sounds versus new clicking, buzzing, or repeated start attempts.
- Check for heavy frost on the back wall of the freezer (often points to a defrost issue).
- Look for water under the refrigerator or ice buildup that can indicate a drain problem.
If the refrigerator is warm, start with the most common non sealed-system causes before assuming a major failure.
| Symptom | Common cause | Example part for LRBN22511TT |
|---|---|---|
| Warm fridge or freezer, frost buildup | Defrost system not working | Refrigerator defrost sensor assembly 6615JB2005C |
| Warm temps, fan noise changes, poor airflow | Evaporator airflow issue | Refrigerator evaporator fan blade 5901JJ1005A |
| Intermittent cooling, odd temperature swings | Temperature sensor issue | Refrigerator thermistor 6500JB2002T |
| Water leaks, ice buildup near drain | Clogged or damaged drain path | Refrigerator drain tube 5251JA3003D |
A “not cooling” complaint can come from a simple airflow or defrost failure that is much less expensive than sealed-system work. Checking the basics first helps you avoid replacing the wrong part and gets food-safe temperatures back faster.
Use the LRBN22511TT owner’s manual for the troubleshooting charts (noise, ice maker performance, odors, and water in the defrost drain pan) and for control-setting guidance.

What is the bottom part of a refrigerator called?
The bottom part of an LG LRBN22511TT refrigerator is commonly called the base grille on the outside, and the machine compartment behind it, where key cooling components (like the compressor and condenser area) are located. For safe access and removal steps, use the LRBN22511TT owner’s manual.
Depending on whether you mean the exterior cover or the area behind it, the “bottom part” can be called:
- Base grille (the front lower grille you can remove for cleaning or service access)
- Machine compartment (the space behind the grille that houses cooling-system components)
- Lower access area (a general term for the service space at the bottom)
- Drain pan area (underneath, where defrost water can evaporate)
The bottom area is important because it supports cooling performance and airflow.
- Compressor (pumps refrigerant through the sealed system)
- Condenser coils or condenser tubing (releases heat)
- Condenser fan (moves air across the condenser area on many models)
- Electrical components and wiring connections
- Drain pan (collects defrost water)
| What you mean | Common name | Where it is |
|---|---|---|
| The removable front cover at the bottom | Base grille | Front, bottom of refrigerator |
| The service area behind the cover | Machine compartment | Behind the base grille |
| The underside area where water may collect | Drain pan area | Under the cabinet |
Knowing the correct name helps you find the right instructions and parts, and it also helps you stay safe. The LRBN22511TT manual specifically warns against putting hands or tools into vents, the base grille area, or the bottom of the refrigerator because of injury and electrical shock risk.
Before inspecting or cleaning the bottom area:
- Unplug the refrigerator before reaching near wiring or moving parts
- Avoid inserting hands or metal tools into vents or the base grille opening
- Keep the refrigerator properly spaced for airflow (tight clearances can hurt cooling)
- Reinstall the base grille securely after service so airflow stays correct
