What is top mount and bottom mount refrigerator?
A top-mount refrigerator has the freezer on top and the fresh-food section below; a bottom-mount refrigerator (like Maytag MFF2258FEZ07) puts the freezer on the bottom so everyday refrigerated items sit closer to eye level. Bottom-mount designs are often preferred for convenience.
Quick comparison
| Feature | Top mount | Bottom mount (bottom freezer) |
|---|---|---|
| Freezer location | Top | Bottom |
| Fresh-food access | Lower, more bending | Higher, less bending |
| Typical layout | Single fridge door | Often French doors on top |
| Best for | Frequent freezer use | Frequent fresh-food use |
How to choose between them
- Choose top mount if you use the freezer most and want the simplest layout.
- Choose bottom mount if you access fresh food many times a day and want less bending.
- Consider door swing and clearance; French-door bottom mounts need side clearance for both doors.
- Think about storage style; bottom freezers use baskets, which can stack items but may hide smaller packages.
- Match the style to your kitchen workflow (meal prep, kids grabbing snacks, bulk frozen storage).
Why it matters
Refrigerator style affects daily comfort and organization. With a bottom-mount unit like MFF2258FEZ07, the items you reach for most (milk, produce, leftovers) typically sit higher, while frozen foods are stored below in pull-out baskets.

What is the most common problem with Maytag refrigerators?
The most common Maytag refrigerator problem is a cooling complaint (fresh food not cold enough, freezer warming, or the unit running constantly). On the Maytag MFF2258FEZ07, the most frequent root causes are airflow restrictions, dirty condenser coils, door sealing issues, or a failing evaporator fan system.
Most common causes (and what to check first)
- Condenser coils are dirty: reduced heat release makes the compressor run longer and cooling suffers.
- Door not sealing: warm, moist air leaks in and causes temperature swings and frost.
- Evaporator fan not moving air: the freezer may get cold but the refrigerator section warms.
- Temperature sensor (thermistor) drifting: the control can misread temps and under-cool or overrun.
- Ice maker issues: low ice production or no ice from water supply problems or a failed ice maker.
Quick troubleshooting steps for MFF2258FEZ07
- Set temps to typical targets: 0°F freezer, 37°F refrigerator.
- Clean condenser coils and confirm the unit has airflow behind and underneath.
- Check for a tight door seal using the “paper test” (paper should drag when pulled).
- Listen for the evaporator fan in the freezer; it should run when the compressor is running.
- If the door light stays on or the fan stops when the door closes, test the door switch.
Parts that commonly solve these symptoms
| Symptom | Common part to inspect/replace | What it affects |
|---|---|---|
| Warm fridge, frost, sweating | Whirlpool refrigerator door gasket (gray) W10443316 | Air leaks and moisture intrusion |
| Fan not running, intermittent cooling | Refrigerator door switch W11396033 | Fan and light logic |
| No airflow noise, warm fresh food | Refrigerator evaporator motor W11024089 | Cold air circulation |
| Fan runs but weak airflow | Refrigerator evaporator fan blade WP2169142 | Air movement across evaporator |
| Temps swing, odd cycling | Refrigerator thermistor 12002355 | Temperature feedback to control |
| No ice or low ice | Assembly, icemaker (complete) W11692144 | Ice production |
Why it matters
Cooling problems usually get worse over time; longer run times increase energy use and can lead to heavy frost, food spoilage, and compressor strain. Catching a simple airflow or door-seal issue early is often the fastest, lowest-cost fix.

Why does my Maytag bottom freezer build up ice on the bottom?
Ice on the bottom of the freezer in a Maytag MFF2258FEZ07 bottom-mount refrigerator almost always happens when the defrost drain clogs. Defrost water can’t flow to the drain pan, so it refreezes on the freezer floor and builds into a thick ice sheet.
What’s happening inside the freezer
During normal operation, frost melts off the evaporator during defrost and should run into a drain trough, down a drain tube, and into a pan underneath. When that drain path is blocked (usually by ice, food debris, or sludge), water backs up and freezes at the lowest point.
Most common causes
- Ice plug in the drain hole from repeated partial thawing
- Debris in the drain trough (crumbs, packaging bits)
- Drain tube restricted or kinked
- Door left slightly ajar causing heavy frost that overwhelms the drain
- Warm, humid air leaks from a worn door gasket
Quick checks we recommend (no parts required)
- Unplug the refrigerator before working in the freezer.
- Remove the freezer drawer and look for a solid ice “lake” on the floor.
- Find the drain opening under/behind the rear freezer panel area.
- Melt the ice with a hair dryer on low or by placing towels and letting it thaw.
- Flush the drain with hot water using a turkey baster until it flows freely.
- Confirm the refrigerator doors close tightly and evenly.
Parts that commonly relate to this symptom
If the drain keeps freezing back up, the drain tube or air leaks are usually involved.
| Symptom you notice | Likely area | Helpful part to check |
|---|---|---|
| Ice returns in 1 to 3 weeks | Drain line restriction | Extension-dr W10619951 |
| Frost buildup plus ice sheet | Door not sealing | Whirlpool refrigerator door gasket (gray) W10443316 |
| One door feels “loose” or doesn’t shut the same | Door alignment/seal issue | Whirlpool refrigerator door gasket, left (gray) W10830283 or whirlpool refrigerator door gasket, right (gray) W10830162 |
Why it matters
A clogged defrost drain can lead to recurring ice buildup, reduced airflow, warmer freezer temperatures, and water leaking when the ice melts. Clearing the drain restores normal defrost drainage and helps the freezer maintain consistent cooling.

Why is my Maytag refrigerator leaking from the bottom?
Water leaking from the bottom of your Maytag MFF2258FEZ07 refrigerator is usually caused by a clogged defrost drain that overflows into the fresh-food section and runs down to the floor, or by a water supply leak from the ice maker line or inlet valve area.
Quick checks we recommend first
- Look for a sheet of ice or standing water under the crisper drawers (points to a defrost drain issue).
- Check the water filter area and the back lower area for drips (points to a supply leak).
- Inspect the freezer floor for ice buildup (often tied to a blocked drain).
- Verify the refrigerator is level; a forward tilt can encourage water to spill out.
- Confirm the doors close tightly; warm air can increase frost and drain clogs.
Most common causes (and what to do)
| What you see | Most likely cause | What to do next |
|---|---|---|
| Water under crispers, then puddle on floor | Defrost drain clogged or frozen | Clear the drain opening; flush with hot water and a turkey baster. |
| Puddle near front corners | Door not sealing, excess frost melt | Inspect and clean the gasket; warm and reshape if warped. |
| Water near back/bottom, especially after ice maker use | Leaking water line connection or valve area | Tighten fittings; inspect tubing for cracks; replace damaged parts. |
| Intermittent leaking with temperature swings | Drain tube not routing water to the pan | Check the drain tube for kinks or blockage. |
Parts that commonly relate to bottom leaks on this model
If you find a specific failure point, these model-matched parts are often involved:
- Extension-dr W10619951 (drain tube extension; helps route defrost water to the drain pan)
- Whirlpool refrigerator door gasket, right (gray) W10830162 (helps prevent warm-air leaks that create excess frost)
- Whirlpool refrigerator door gasket, left (gray) W10830283 (same purpose on the left door)
Why it matters
A small leak can turn into recurring ice buildup, warmer refrigerator temperatures, and floor damage. Fixing the drain path or sealing issue early keeps defrost water going where it belongs: into the drain pan for evaporation.
