What is the top mount refrigerator?
A top-mount refrigerator is a classic fridge layout where the freezer compartment is on top and the fresh-food (refrigerator) compartment is below. Your Magic Chef CTB1722GRW uses this design to keep everyday refrigerated items at easy reach while storing frozen foods overhead.
How a top-mount layout is set up
- Freezer on top: shelves or a bin for frozen foods
- Refrigerator below: main storage for fresh foods, drawers, and door bins
- Shared cooling system: cold air is produced at the evaporator and distributed to both sections
- Separate doors: helps reduce cold-air loss compared to a single-door design
Why people choose a top-mount refrigerator
Top-mount models are popular because they are straightforward, space-efficient, and typically easy to service. They also tend to have fewer complex door mechanisms than some multi-door designs.
| Feature | Top-mount refrigerator | Bottom-freezer refrigerator |
|---|---|---|
| Freezer access | Eye level | Lower, often a pull-out drawer |
| Fresh-food access | Lower shelves require bending | More items at eye level |
| Typical complexity | Lower | Moderate |
| Common maintenance items | Door gasket, thermostat, fan motor | Door rails, drawer seals, fan motor |
Why it matters for troubleshooting and parts
Knowing you have a top-mount design helps narrow down common symptoms and the parts that usually cause them.
- Frost buildup in the freezer can point to the defrost system (for example, a refrigerator defrost heater WP61001946 or refrigerator defrost bi-metal thermostat WP61005254).
- Warm refrigerator section with a cold freezer often points to airflow issues, including the evaporator fan (such as a refrigerator evaporator fan motor WP61004888).
- Moisture or temperature swings can also relate to controls like a refrigerator thermostat WP627985 or sealing issues like a refrigerator door gasket WP61005587.

How do you defrost a Magic CTB1722GRW refrigerator?
To defrost your Magic Chef CTB1722GRW top-mount refrigerator, move food to a cooler, turn the temperature control to OFF (or unplug the refrigerator), and let the frost melt naturally. Keep towels handy and empty the drip pan as needed; most defrosts take a few hours.
Quick defrost steps (safe and effective)
- Unplug the refrigerator (or switch the control to OFF).
- Move perishable food to a cooler; keep freezer items insulated.
- Open the freezer door to speed melting.
- Place towels under the front edge and check for water runoff.
- Do not chip ice with sharp tools; it can puncture the evaporator.
- When ice is gone, wipe the freezer dry and restart the unit.
Speed it up (without damaging the liner)
Use gentle heat only:
| Method | How to do it | What to avoid |
|---|---|---|
| Bowl of hot water | Set on a towel in the freezer; refresh as it cools | Don’t spill water into vents or controls |
| Warm, damp cloth | Press against thick frost to loosen it | Don’t use boiling water directly on plastic |
| Hair dryer (low) | Keep moving, 6 to 12 inches away | Don’t overheat one spot or aim at wiring |
If frost keeps coming back
Heavy frost usually means warm, moist air is getting into the freezer or the defrost system is not clearing ice.
- Check the door seal for gaps or tears; replace the refrigerator door gasket WP61005587 if it is not sealing.
- Make sure the door closes fully and nothing is blocking it.
- If the freezer wall is packed with ice and airflow is weak, the defrost heater or thermostat may be failing; common replacements include the refrigerator defrost heater WP61001946 and refrigerator defrost bi-metal thermostat WP61005254.
Why it matters
Defrosting restores airflow across the evaporator coil, which helps the evaporator fan move cold air into the fresh food section. That improves cooling performance, reduces run time, and helps prevent temperature swings.

What is the upper part of a fridge called?
On a Magic Chef CTB1722GRW top-mount refrigerator, the upper compartment is the freezer. It’s the section designed to keep foods frozen, and it often houses ice-making components (like an ice tray or an optional ice maker).
What the freezer does
The freezer compartment is built to:
- Maintain temperatures cold enough to keep food frozen long-term
- Freeze fresh foods quickly when airflow is good
- Support ice production (manual trays or an ice maker kit, if equipped)
- Circulate cold air that helps cool the refrigerator section below
Common freezer-related parts you might see
Depending on how your CTB1722GRW is equipped, these parts are commonly associated with the upper section:
- Ice-making components such as the refrigerator ice tray WP841180A
- Defrost system components that prevent frost buildup
- Airflow components that move cold air through the freezer and into the fresh-food section
Quick part reference (examples)
| Symptom in upper compartment | Common area to check | Example part on this model page |
|---|---|---|
| Frost building up on back wall | Defrost system | Refrigerator defrost heater WP61001946 |
| Warm freezer, fridge also warming | Air circulation | Refrigerator evaporator fan motor WP61004888 |
| Ice cubes not forming well (manual) | Ice tray condition | Refrigerator ice tray WP841180A |
Why it matters
When the freezer (upper compartment) has airflow or defrost problems, you’ll often notice temperature swings, frost buildup, or weak cooling in the refrigerator section. Keeping vents clear and addressing frost early helps the whole unit cool correctly.

How heavy is a Magic CTB1722GRW mini fridge?
The Magic Chef CTB1722GRW is a full-size top-mount refrigerator, not a mini fridge. For moving and delivery planning, most top-mount refrigerators in this class weigh about 200 to 250 lb empty; plan on two adults plus an appliance dolly.
What weight to plan for
Use these practical planning numbers when you do not have the exact spec label handy:
- Empty refrigerator: 200 to 250 lb
- With food and bins: add 30 to 80 lb
- With doors removed (if needed for tight spaces): subtract 20 to 40 lb
- Stairs: plan for an extra helper and a strap system
- Truck loading: use a ramp; do not lift the full weight
| Scenario | What to assume | Why it matters |
|---|---|---|
| Moving (empty) | 200 to 250 lb | Chooses the right dolly and manpower |
| Moving (loaded) | 230 to 330 lb | Prevents tip-over and back strain |
| Tight doorway | Remove doors if needed | Avoids cabinet and gasket damage |
Safe moving checklist (protects the sealed system)
- Unplug and empty the refrigerator; remove the ice tray and loose bins.
- Tape doors shut and secure shelves and drawers so they do not shift.
- Keep the unit upright during transport.
- After moving, let it stand upright before plugging in (several hours is standard practice).
Why it matters
Planning for a 200 to 250 lb appliance helps prevent injuries and reduces the chance of damaging the compressor system, hinges, and door seal. If the door seal gets nicked or starts leaking after a move, replacing the refrigerator door gasket WP61005587 helps restore proper cooling efficiency.
