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 Maytag MTB2455DRW uses this design to keep everyday refrigerated items at easy reach while storing frozen foods above.
How a top-mount layout is organized
In most top-mount refrigerators (including Maytag models like MTB2455DRW), you will typically see:
- A top freezer section with shelves or a bin for frozen foods
- A lower fresh-food section with adjustable shelves and crisper drawers
- A temperature control system that cools the freezer first, then routes cold air to the refrigerator
- Door bins in both sections for frequently used items
Top-mount vs. other refrigerator styles
Here is a quick comparison to help you identify what you have and why it feels different day to day:
| Style | Freezer location | What it’s best for | Common tradeoff |
|---|---|---|---|
| Top-mount | Top | Simple layout, usually lower cost, easy freezer access | Bending more for fresh-food items |
| Bottom-mount | Bottom | Fresh-food items at eye level | Frozen items lower down |
| Side-by-side | Left or right side | Narrow door swing, easy access to both sections | Narrower shelves for wide items |
Why it matters for troubleshooting and parts
The “top-mount” design affects how cooling and airflow problems show up. For example, if the freezer is cold but the refrigerator section is warm, the issue is often related to airflow between compartments (such as frost buildup, a weak evaporator fan, or blocked vents).
- If you hear unusual fan noise or the refrigerator side is warming up, use how to fix your evaporator cooling fan
- If you are dealing with odors after a spill or power outage, use how to get rid of refrigerator smells

What are the disadvantages of a top mount fridge?
Top-mount refrigerators like the Maytag MTB2455DRW are reliable and straightforward, but the main disadvantages are less convenient fresh-food access (you bend more), fewer built-in organization features than many bottom-freezer styles, and fewer dispenser options on many models.
Common disadvantages (what you notice day to day)
- More bending for fresh food: the refrigerator section sits lower, so produce drawers and shelves are accessed from a lower position.
- Less flexible organization: many top-mount designs have fewer specialty drawers, dividers, and wide pantry-style storage than some bottom-mount layouts.
- Freezer at eye level can feel cramped: the upper freezer is convenient for frozen items, but can be tighter for bulky boxes.
- Fewer exterior features on many models: through-the-door water and ice are less common on top-mount units.
- Temperature swings from frequent freezer use: opening the top freezer often can slightly affect overall airflow, especially if vents get blocked.
Quick comparison: top mount vs. bottom freezer
| Feature | Top mount (like MTB2455DRW) | Bottom freezer |
|---|---|---|
| Fresh-food access | Lower, more bending | Higher, easier access |
| Freezer access | Convenient, upper level | Lower drawer, easier for large items |
| Organization | Often simpler | Often more configurable |
| Dispensers | Less common | More common on many models |
How to reduce the downsides
- Keep everyday items on the upper refrigerator shelves to reduce bending.
- Avoid blocking air vents with tall containers; airflow issues can make temps uneven.
- Use bins to group foods (snacks, deli, breakfast) so you open the door for less time.
- If you have a water system, replace filters on schedule to keep flow and taste consistent; see how to replace the water filter in a Maytag refrigerator.
Why it matters
Most “disadvantages” are really about ergonomics and storage style. If you shop often for fresh foods, the lower fridge access is the biggest tradeoff; if you use frozen foods more, the upper freezer can be a benefit.

What is the average lifespan of a Maytag refrigerator?
Most Maytag refrigerators, including top-mount models like MTB2455DRW, typically last 12 to 15 years with normal household use. Consistent cleaning, good airflow around the cabinet, and fixing small cooling or water issues early are the biggest factors that keep a refrigerator running longer.
Typical lifespan ranges (what to expect)
Refrigerator life varies most by usage, maintenance, and how hard the compressor has to work.
| Refrigerator type | Typical lifespan | Notes |
|---|---|---|
| Top-mount (freezer on top) | 12 to 15 years | Often a strong value for longevity and efficiency |
| Side-by-side | 10 to 14 years | More doors and features can mean more wear points |
| French door | 9 to 13 years | More seals, drawers, and airflow paths to maintain |
What shortens lifespan fastest
These are the most common conditions that push a refrigerator to fail earlier.
- Dirty condenser area (dust and pet hair make the system run hotter and longer)
- Poor ventilation (tight enclosure, blocked rear or bottom airflow)
- Door seal leaks (warm air intrusion causes long run times and frost issues)
- Overloading or blocking vents inside (reduces airflow to the fresh food section)
- Ignoring early symptoms (warm temps, unusual noises, water leaks)
Maintenance that adds years
A few simple habits reduce compressor run time and prevent common failures.
- Keep the condenser area clean and maintain clearance for airflow
- Set stable temperatures (avoid frequent dial changes)
- Keep door gaskets clean and ensure doors close fully
- Level the refrigerator so doors self-close and seals seat evenly
- Replace water filtration on schedule if your unit uses one (see how to replace the water filter in a Maytag refrigerator)
Why it matters
A refrigerator usually wears out from heat and long run times. When airflow is restricted or seals leak, the sealed system works harder, which accelerates wear on the compressor and cooling components.

How do I find my Maytag fridge model number?
On a Maytag top-mount refrigerator like model MTB2455DRW, the model number is typically printed on a rating label inside the fresh food compartment, most often on the upper left interior frame or near the control housing.
Where to look first (fastest checks)
- Open the refrigerator (fresh food) door and check the upper left interior frame.
- Look along the side wall just inside the door opening.
- Check the underside or edge of the temperature control housing (control panel area).
- If you do not see it in the refrigerator section, check the freezer compartment side walls.
- Look for a label that includes both model and serial numbers.
What the label looks like
Most Maytag rating labels include:
- The word Model followed by letters and numbers (example format: MTB2455DRW)
- A Serial number
- Electrical info (volts/amps)
- Sometimes a bar code
| What you need | Why it matters | Example |
|---|---|---|
| Model number | Ensures parts fit your exact refrigerator | MTB2455DRW |
| Serial number | Helps match production series and revisions | Varies |
Why it matters
Using the exact model number prevents ordering the wrong refrigerator parts (like a door gasket, evaporator fan motor, or water filter) and helps us match diagrams and compatible replacements.

What are the dimensions of a Maytag refrigerator?
Maytag refrigerator dimensions vary by model and configuration; for your Maytag MTB2455DRW top-mount refrigerator, the most reliable way to size it is to measure the cabinet and doors directly (including handles) and plan installation clearances around those measurements.
How to measure your MTB2455DRW (the numbers you actually need)
Use a tape measure and record each dimension twice: once for the cabinet only, and once including doors and handles.
- Height: floor to the top of the hinge cover (also note height with leveling legs adjusted)
- Width: widest point with doors closed (include door edges if they protrude)
- Depth: back of cabinet to front; measure without handles and with handles
- Door swing: measure how far the doors need to open to clear shelves and drawers
- Ventilation clearance: leave space behind and above for airflow
Typical top-mount size range (for planning only)
If you are estimating before measuring, most full-size Maytag top-mount refrigerators land in these bands:
| Dimension | Typical range | What to measure on yours |
|---|---|---|
| Height | 65 to 70 in. | To top of hinge cover |
| Width | 29 to 33 in. | Widest point with doors closed |
| Depth | 30 to 34 in. | With and without handles |
Fit and clearance checklist
These checks prevent “it fits in the opening but not in real life” problems:
- Compare opening width to refrigerator width plus side clearance
- Confirm depth so doors and handles do not block walkways
- Verify overhead clearance so the unit can be rolled in and leveled
- Measure the delivery path (doorways, turns, stairs)
Why it matters
Exact dimensions affect door swing, airflow, and whether drawers can open fully. If your MTB2455DRW has a water filter, service access space matters too; see how to replace the water filter in a Maytag refrigerator for typical filter locations and clearance needs.
