Maytag MFF2558FEZ01 bottom-mount refrigerator Parts

On a Maytag MFF2558FEZ01 bottom-mount refrigerator, the “bottom part” most people mean is the compressor compartment (the machinery area underneath or behind the lower rear cover). The main component there is the compressor, which pumps refrigerant through the sealed cooling system.

What parts are typically in the bottom rear area?

Depending on the exact layout, the lower rear section commonly includes:

• Compressor (the pump for the sealed system)
• Condenser coil (releases heat from the refrigerant)
• Condenser fan (moves air across the condenser on many models)
• Start device/overload and wiring connections
• Drain pan (catches defrost water so it can evaporate)

For this model, a key “bottom area” sealed-system part is the refrigerator compressor W10233960.

Quick guide: “bottom of the fridge” terms

What you see/mean	Common name	What it does
Big black can-shaped motor	Compressor	Circulates refrigerant to create cooling
Hot tubing/coil near compressor	Condenser	Dumps heat so the fridge can cool
Water collecting underneath	Drain pan	Evaporates defrost water
Lower drawer area inside	Freezer compartment	Stores frozen food (not a mechanical part)

Why it matters

Using the right name helps you order the correct Maytag refrigerator parts and troubleshoot faster. For example, “freezer drawer” issues point to slides or baskets, while “bottom rear” noises or heat point to the compressor/condenser area.

Ordering the right part

When you are ready to replace a part, match by model number MFF2558FEZ01 and the exact part ID. You can order parts from the list for this model, or search by model on Sears PartsDirect.

For most households, a bottom-freezer refrigerator like the Maytag MFF2558FEZ01 is the better choice because the fresh-food section (used most often) sits at eye level, so you bend less and access everyday items faster; top-freezer models can be more budget-friendly and slightly simpler.

Quick comparison: top vs bottom freezer

Feature	Bottom freezer (like MFF2558FEZ01)	Top freezer
Everyday access	Best for fresh-food items at eye level	More bending for fresh-food items
Freezer access	More bending for frozen items	Frozen items at eye level
Organization	Often better freezer baskets and drawers	Often simpler shelves
Typical cost	Usually higher	Usually lower

How to choose what is “better” for you

• Choose bottom freezer if you use the refrigerator section most and want less bending.
• Choose top freezer if you want a simpler layout and typically lower purchase cost.
• If you cook with frozen foods often, a top freezer can feel more convenient day to day.
• If you want better freezer organization, bottom-freezer drawer baskets are usually easier to sort.
• If door sealing and temperature stability matter, focus on gasket condition and door alignment more than freezer position.

Why it matters (comfort, efficiency, and maintenance)

Freezer position mostly affects ergonomics and how you organize food. Energy use depends more on habits (door-open time, room temperature, condenser cleanliness) and whether the doors seal tightly than on whether the freezer is on top or bottom.

Parts that support performance on this model

If you are trying to improve cooling consistency or reduce frost and moisture issues on the Maytag MFF2558FEZ01, these model-matched parts are commonly involved:

• Whirlpool refrigerator door gasket (gray) W10443320 (helps prevent warm air leaks)
• Whirlpool refrigerator door gasket, right (gray) W10830162 (helps prevent warm air leaks)

Ice building up on the bottom of the freezer in your Maytag MFF2558FEZ01 almost always happens when the defrost drain clogs. During defrost, meltwater can’t flow down the drain, so it refreezes on the freezer floor and gradually forms a thick ice sheet.

What’s happening inside the freezer

When the refrigerator goes into defrost, frost on the evaporator melts and should drain to a pan underneath the cabinet. If the drain hole or drain tube is blocked by ice, food debris, or sludge, water backs up and freezes at the lowest point.

Common causes

• Drain hole iced over from repeated partial clogs
• Debris (crumbs, packaging bits) washed into the drain trough
• Drain tube restricted or kinked behind the unit
• Door not sealing well, adding excess moisture that overwhelms the drain
• Freezer left open or not closing fully (more humid air enters)

How we recommend fixing it

1. Unplug the refrigerator.
2. Remove the freezer drawer/basket and take out the ice buildup (warm towels help).
3. Locate the drain trough under the evaporator cover area and clear the drain hole.
4. Flush the drain with hot water (a turkey baster works well) until it flows freely.
5. Check the drain tube at the back for restrictions; replace the drain tube if it’s damaged.

If the drain tube is cracked, missing, or won’t clear, replacing it is the reliable fix: extension-dr W10619951.

Quick checks that prevent the ice from coming back

• Keep freezer food packages from blocking the rear air vents
• Make sure the freezer closes tightly every time
• Inspect door gaskets for gaps or tears
• Clean spills and crumbs before they wash into the drain

Door seal check (simple test)

Check	What you do	What it means
Dollar-bill test	Close door on a bill and pull	Easy pull = gasket leak likely
Visual gap check	Look for warped corners	Gaps add moisture and frost
Frost pattern	Heavy frost near door	Often points to air leak

Why it matters

A clogged defrost drain can cause recurring ice sheets, drawer rails that bind, and water leaks when the ice melts. Clearing the drain restores normal defrost drainage and keeps temperatures more stable.
