Estate TT18HPXLQ01 top-mount refrigerator Parts

A fridge with the freezer on top is called a top-freezer refrigerator, also commonly called a top-mount refrigerator. Your Estate TT18HPXLQ01 is this style, with the freezer compartment above the fresh-food compartment and separate doors.

Common names you will see

• Top-freezer refrigerator
• Top-mount refrigerator
• Freezer-on-top refrigerator
• Two-door top-freezer (side-swing doors)

How to identify it quickly

Use these visual and functional clues:

• Freezer compartment is physically above the refrigerator section
• Two separate doors (one for freezer, one for fresh food)
• Temperature controls typically manage freezer cooling first, then fresh-food airflow
• Evaporator fan circulates cold air from the freezer into the refrigerator section

Refrigerator style name	Freezer location	Typical door layout
Top-freezer (top-mount)	Top	Two side-swing doors
Bottom-freezer	Bottom	Drawer or lower door
Side-by-side	Left side	Two tall doors
French door	Bottom	Two upper doors + lower freezer drawer

Why it matters (parts and troubleshooting)

Knowing the style helps us match the right parts and the most likely cooling system layout. For example, top-mount designs commonly rely on the freezer evaporator fan and defrost system to keep both sections cold.

If you are troubleshooting warm temperatures or weak airflow in the fresh-food section, these model-matched parts are often involved:

• Evaporator motor WPW10189703 (drives airflow across the evaporator)
• Defrost bi-metal WP4387503 (helps protect the defrost circuit from overheating)
• Refrigerator evaporator fan blade WP2163777 (moves air; damage can reduce airflow)

A top-mount refrigerator like the Estate TT18HPXLQ01 is usually the better choice when you want lower upfront cost, simple reliability, and strong energy efficiency. A bottom-mount is usually better when you want fresh-food items at eye level and easier access to the refrigerator section.

Quick comparison (what most homeowners notice)

• Top-mount (freezer on top): typically costs less, fewer complex features, easy to service
• Bottom-mount (freezer on bottom): refrigerator shelves are higher, less bending for daily items, often more drawer-style organization
• Either style: performance depends most on airflow, door sealing, and temperature control

Feature	Top-mount	Bottom-mount
Everyday access to fresh food	Good	Best
Upfront price	Best	Higher
Freezer access	Best for frequent freezer use	More bending for freezer
Repair simplicity	Often simpler	Often more complex
Best fit for	Budget, reliability	Convenience, organization

How to decide for your kitchen and habits

Use these practical tie-breakers:

• If you use the refrigerator section far more than the freezer, bottom-mount usually feels better day to day.
• If you want a straightforward, durable layout, top-mount is usually the better long-term value.
• If you have tight space, measure door swing and clearance; top-mounts often fit well in smaller kitchens.
• If you are trying to cut food waste, bottom-mount layouts can make fresh items easier to see.

Why it matters (performance and operating cost)

“Better” is mostly about how you use the appliance. Both styles can cool well, but any refrigerator will struggle if airflow is blocked, the condenser area is dusty, or doors do not seal tightly. If you are troubleshooting cooling or temperature swings on a top-mount like the TT18HPXLQ01, the evaporator fan system is a common place to start; see how to fix your evaporator cooling fan.

Top-mount refrigerators like the Estate TT18HPXLQ01 are reliable and efficient, but the main disadvantages are convenience and storage layout: fresh-food items sit lower (more bending), freezer access is higher, and you typically get fewer premium organization and dispenser features than other styles.

Common disadvantages (what you will notice day to day)

• More bending for fresh food: the refrigerator section is below the freezer, so you reach down more often.
• Less “grab-and-go” organization: many top-mount designs have fewer adjustable bins, deli zones, and wide pantry drawers than newer bottom-mount styles.
• Fewer built-in features: in-door water and ice are less common on top-mount models.
• Freezer space can feel tighter: the top freezer is often narrower and can be harder to organize for bulky items.
• Door swing clearance matters: in tight kitchens, door swing and shelf access can be less convenient.

Quick comparison: top-mount vs. other common styles

Feature	Top-mount (TT18HPXLQ01 style)	Bottom-mount	Side-by-side
Fresh food access	Lower (more bending)	Eye-level (easier)	Mid-level (mixed)
Freezer access	Higher (easy reach)	Lower (more bending)	Mid-level (narrow shelves)
Organization features	Basic to moderate	Often best	Moderate
Dispensers	Less common	More common	Common

Why it matters

If you use fresh foods most often, a top-mount layout can feel less ergonomic over time. If you use frozen foods more often, the higher freezer can be a plus. The “best” choice usually comes down to how you cook, your kitchen space, and whether you want features like in-door water and ice.

Tips to make a top-mount easier to live with

• Keep everyday items on the top refrigerator shelf to reduce bending.
• Use clear bins to group snacks, dairy, and condiments.
• Avoid overpacking; airflow helps temperature stability.
• If doors do not seal well, fix alignment and sealing issues early using how to fix a fridge door seal.

On an Estate TT18HPXLQ01 top-mount refrigerator, the upper section is typically the freezer compartment. That is the insulated space designed to hold frozen food and, on many models, it is also where the ice maker mounts.

Common names you may hear

• Freezer compartment (most common)
• Freezer section
• Freezer cabinet
• Freezer liner (the interior plastic “box” inside the freezer)
• Freezer door (the upper door on a top-mount unit)

What the upper (freezer) section does

The freezer compartment is more than storage; it supports cooling and airflow for the whole refrigerator.

Freezer-related function	What you notice when it is working	What you notice when it is not
Freezing and long-term storage	Ice stays solid, food stays frozen	Soft ice cream, thawing food
Airflow to the fresh-food section	Refrigerator stays evenly cold	Refrigerator warms up or has hot spots
Defrost management	Minimal frost buildup	Heavy frost, reduced airflow
Ice production (if equipped)	Steady ice output	No ice or small/hollow cubes

Parts commonly associated with the upper section

If you are troubleshooting cooling, frost, or ice issues on TT18HPXLQ01, these parts are often involved:

• Refrigerator ice maker W11700559 (if your unit is equipped)
• Defrost bi-metal WP4387503 (helps protect the defrost circuit)
• Refrigerator evaporator fan blade WP2163777 (moves cold air through the freezer and into the refrigerator)

Why it matters

When the freezer compartment has poor airflow or heavy frost, the fresh-food section often warms up even if the compressor is running. Identifying the “upper part” as the freezer helps you focus troubleshooting on the evaporator area, defrost system, and ice maker (if installed).
