What is the bottom part of a refrigerator called?
On the Kenmore 79578403801 bottom-mount refrigerator, the bottom area is commonly called the machine compartment (also referred to as the compressor compartment). It sits behind the base grille and houses key cooling parts like the compressor, condenser area, and related airflow components.
What you will find in the bottom section
The lower compartment is more than a cover; it protects and ventilates the refrigeration system.
- Base grille: the front lower grille you remove for access and cleaning
- Compressor area: where the sealed system pump sits
- Condenser area: where heat is rejected from the refrigerant
- Drain pan: catches defrost water so it can evaporate
- Wiring and airflow path: supports condenser fan airflow (on many bottom-mount designs)
For model-specific access and safety notes (including base grille removal), use the 79578403801 owner's manual.
Common names customers use (and what they mean)
| What people call it | What it usually refers to | Where it is |
|---|---|---|
| Bottom grille | Base grille | Front, bottom of cabinet |
| Bottom panel | Toe kick or lower cover area | Front, bottom |
| Back bottom cover | Rear access cover (varies by design) | Rear, lower section |
| Motor area | Machine compartment | Bottom, behind grille |
Why it matters
Knowing the correct name helps when ordering parts and troubleshooting issues like warm temperatures, unusual noises, or airflow problems. It also helps you follow safe access steps because the manual warns against putting hands or tools into the base grille or bottom area.
Quick safety and care tips
- Unplug the refrigerator before removing covers or reaching near wiring.
- Use a soft brush or vacuum to remove dust from accessible areas.
- Keep hands and metal tools out of vents and the bottom opening.
- Reinstall the base grille fully so airflow is not restricted.

Is a top mount or bottom mount fridge better?
A bottom-mount refrigerator like Kenmore 79578403801 is usually better for everyday convenience because fresh food sits at eye level and the freezer is in a pull-out drawer. A top-mount is often the better pick if you want the simplest layout and typically lower energy use.
Quick comparison
| Feature | Bottom-mount (like 79578403801) | Top-mount |
|---|---|---|
| Fresh food access | Easier (less bending) | More bending |
| Freezer access | Drawer style, organized bins | Shelf style, easy to see |
| Organization | Strong (baskets, dividers) | Basic |
| Energy use | Often slightly higher | Often slightly lower |
| Cost to buy/repair | Often higher | Often lower |
When a bottom-mount is the better choice
- You use the refrigerator section more than the freezer.
- You want better organization for frozen foods (drawer baskets help).
- You prefer easier access for heavy items like milk, produce drawers, and leftovers.
- You want features common on bottom-mount designs (multi-airflow cooling, door storage).
When a top-mount is the better choice
- You want a simpler, budget-friendly design.
- You want a layout that is typically more energy-efficient.
- You prefer a freezer you can scan quickly without pulling out a drawer.
- You want fewer moving drawer components to maintain over time.
Why it matters
The “better” style depends on how you cook and shop. Most households open the refrigerator section far more than the freezer, so bottom-mount models reduce bending and make daily use easier. If you are focused on lowest operating cost and a straightforward layout, top-mount models often win.
Model-specific tip for 79578403801 owners
For best performance on a bottom-mount design, keep vents clear so air can circulate between the freezer and fresh-food sections; our 79578403801 owner's manual covers airflow and control settings.

How much does it cost to replace a refrigerator shelf?
For Kenmore refrigerator model 79578403801, replacing a refrigerator shelf typically costs $20 to $200 for the part, depending on shelf style (glass vs. wire) and whether you replace the full shelf assembly or just a support. Labor is usually $0 if you DIY.
What affects the shelf replacement cost?
- Shelf type: tempered glass shelves usually cost more than wire shelves
- What you replace: full shelf vs. small components (rails, supports, bins)
- OEM vs. aftermarket: OEM parts typically cost more but fit and finish are consistent
- Shipping and availability: large shelves can cost more to ship
- Damage cause: impact cracks or warped frames can require replacing the whole shelf
DIY replacement basics (what we recommend)
Your 79578403801 shelves are adjustable; the manual also notes glass shelves are heavy and can break with sudden temperature changes or impact.
- Unload the shelf completely
- Lift the front edge slightly, then slide the shelf out (typical for this design)
- If it is a glass shelf, handle with two hands and set it on a flat surface
- Reinstall at the height you want for better airflow and easier access
- Use the steps in the 79578403801 owner's manual for the exact removal method for your shelf style
Typical price ranges (parts only)
| Replacement item | Typical cost range | Notes |
|---|---|---|
| Wire shelf | $20 to $80 | Usually the lowest-cost option |
| Glass shelf assembly | $60 to $200 | Higher cost due to tempered glass and frame |
| Door bin or basket | $30 to $200 | Often model-specific and varies by size |
If you are replacing a door bin instead of an interior shelf, a common example for this model is the refrigerator door deep bin 5005JJ2022A.
Why it matters
A cracked or missing shelf reduces usable storage and can block proper air circulation. Keeping shelves correctly positioned helps maintain even cooling and reduces how long the door stays open.

Why is my Kenmore refrigerator leaking from the bottom?
On Kenmore bottom-mount refrigerator model 79578403801, a bottom leak is usually caused by defrost water missing the drain path (a clogged or frozen defrost drain) or a water supply issue for the ice maker or dispenser. Start by checking for ice or debris in the drain area and inspecting the water line connections.
Most common causes (and what to check first)
- Clogged defrost drain: Water from the defrost cycle backs up, then runs into the fresh food section and out the bottom.
- Cracked or shifted drain pan: Defrost water is supposed to collect in the pan; if it is damaged or out of position, water can spill.
- Water line or fitting leak: A slow drip from the supply line, valve area, or tubing can track down and pool under the cabinet.
- Door not sealing: Warm air leaks in, creates excess frost, then more defrost water than normal.
- Ice maker fill or dispenser tubing issue: Leaks can show up as a bottom puddle even when the source is higher up.
Step-by-step troubleshooting
- Unplug the refrigerator and remove food from the area you need to access.
- Look for ice buildup on the freezer floor or under the crisper area; that strongly points to a defrost drain problem.
- Clear the drain path using hot water (turkey baster) and confirm water flows to the drain pan.
- Inspect the drain tube for kinks, splits, or a loose connection; replace if damaged.
- Check the water tubing and fittings for drips, especially after dispensing water or during an ice maker fill.
- Inspect door sealing and hinge alignment; correct sagging doors and clean the gasket sealing surfaces.
Parts that commonly relate to bottom leaks on this model
| Symptom you see | Likely area | Example part to inspect |
|---|---|---|
| Ice sheet on freezer floor | Defrost drain system | Refrigerator drain tube 5251JA3003D |
| Drip near hinge side | Door alignment or closure | Refrigerator door cam latch, left 4430JJ2005B |
| Water trails near dispenser/line | Water tubing connection | Refrigerator water tube fitting 4932JA3002B |
Why it matters
A bottom leak is not just a mess; it can lead to ice buildup, poor cooling, and repeated defrost drain overflows. The manual also notes that you may hear water running into the drain pan during defrost, so when that water cannot drain correctly, leaks are a common result. Use the 79578403801 owner's manual for access steps, door alignment guidance, and troubleshooting checks.
