What's the lifespan of a bottom freezer fridge?
Most bottom freezer refrigerators typically last 15 to 20 years with normal use and routine maintenance. For your Samsung RF28HFEDTSG, lifespan depends most on compressor health, airflow, and keeping the condenser area clean; our RF28HFEDTSG owner's manual covers key care steps that help it reach that range.
Typical lifespan and what affects it
A bottom-mount (bottom freezer) design usually runs longer when the sealed system stays efficient and the fans can move air freely.
Common factors that shorten lifespan:
- Dirty condenser area and restricted airflow
- Door seal leaks that force longer run times
- Ice maker and water system leaks or clogs
- Overpacked compartments that block interior vents
- Skipped maintenance after power outages or moves
Maintenance that helps you reach 15 to 20 years
These are the highest-impact habits for a Samsung bottom-mount refrigerator:
- Vacuum dust from the rear of the refrigerator once or twice a year (do not remove the back cover).
- Keep food from blocking interior air vents; blocked vents can cause overcooling and other issues.
- Use potable water only for the ice maker and dispenser; keep water pressure in the normal operating range.
- If you will be away more than 3 weeks, empty the unit, unplug it, close the water valve, wipe moisture, and leave doors open to prevent odors and mold.
- After a power disconnect, wait at least 5 minutes before plugging back in.
What “end of life” usually looks like
Many refrigerators are still repairable late in life, but these symptoms often signal major wear:
| Symptom | Most likely system involved | Typical next step |
|---|---|---|
| Warm fridge and freezer, running constantly | Sealed system or condenser airflow | Check condenser cleanliness; test cooling performance |
| Clicking, no cooling | Compressor start or compressor | Diagnose compressor circuit; consider compressor repair |
| Heavy frost, poor airflow | Defrost system or evaporator fan | Check defrost heater and fan operation |
| Water under unit or in fresh food section | Drain system or water line | Clear drain and inspect drain tube |
Why it matters
Knowing the 15 to 20 year lifespan helps you decide when a repair is routine maintenance versus when it is time to plan for a larger sealed-system repair (like a compressor) that can extend the refrigerator’s usable life.

What is the most common problem with Samsung refrigerators?
The most common problems we see with Samsung refrigerators, including Samsung model RF28HFEDTSG, are cooling complaints and ice maker issues. These usually trace to restricted airflow from frost buildup, a defrost or drain problem, or a fan that is not circulating cold air correctly; use the RF28HFEDTSG owner's manual for operating and care steps that help prevent repeat icing and temperature swings.
Most common symptoms
- Fresh food section warms up while the freezer still feels cold
- Ice maker stops making ice, makes small cubes, or clumps ice
- Frost or ice buildup on the rear interior panel or around the ice room
- Water under crisper drawers or puddles near the front
- Fan noise (buzzing, rubbing, rattling), especially after doors close
What usually causes it
| System | What goes wrong | What you notice |
|---|---|---|
| Airflow | Frost blocks vents or fan can’t move air | Warm fridge, uneven temps |
| Defrost and drain | Defrost water can’t drain, refreezes | Ice buildup, leaks |
| Temperature sensing | Sensor reads wrong temperature | Overcooling or warming |
Quick checks that fix many “common problems”
- Keep packages clear of interior air vents; blocked vents cause poor circulation.
- After unplugging, wait at least 5 minutes before plugging back in.
- For ice maker issues, confirm the water supply is on and pressure is 20 to 125 psi.
- If you see water inside, clear visible ice or debris at the drain area.
- If frost keeps returning, inspect the defrost system; a failed heater is a common culprit.
Parts often involved on RF28HFEDTSG
- Refrigerator defrost heater DA47-00244U
- Refrigerator temperature sensor DA32-10104N
- Refrigerator fresh food evaporator cover and fan assembly DA97-12608B
- Refrigerator drain tube kit DA97-04049E
Why it matters
Cooling and ice maker problems usually worsen because frost and restricted airflow make the refrigerator run longer, warm food faster, and can lead to leaks. Addressing early signs helps prevent food spoilage and repeat icing.

What is the difference between force defrost RD and FD?
On Samsung RF28HFEDTSG refrigerators, RD and FD are service-style defrost selections used to melt frost; RD is used to defrost the refrigerator (fresh food) cooling system, while FD is used when you want a full forced defrost to clear heavier frost conditions that can affect cooling and ice production. For your model’s control-panel procedure and safety notes, use the RF28HFEDTSG owner's manual.
What each mode is for
- RD (refrigerator defrost): Focuses on defrosting the refrigerator compartment’s evaporator area to restore airflow and normal fresh food temperatures.
- FD (forced defrost): Runs a more aggressive, service-oriented defrost intended to clear significant frost buildup that can impact overall performance.
- Automatic defrost still matters: RF28HFEDTSG is frost-free and normally defrosts on its own; RD/FD are mainly for troubleshooting and clearing ice.
When to use RD vs. FD
Use the symptom location to pick the mode:
| What you notice | Use first | What it helps you do |
|---|---|---|
| Fresh food section warming, weak airflow from fridge vents | RD | Clear frost that blocks the refrigerator evaporator and fan airflow |
| Ice maker area icing up, freezer performance dropping, widespread frost symptoms | FD | Clear heavier frost conditions that can interfere with cooling and ice making |
| You are checking whether the defrost system can produce heat | FD | Force a defrost event so you can confirm melting/heat is occurring |
If the frost comes back quickly
Recurring frost after a forced defrost points to a defrost-system or airflow issue. Common items to check include:
- Defrost heater circuit and connections
- Temperature sensor input
- Evaporator fan operation and air passages
- Door seals and frequent door openings
Parts that often relate to these symptoms on this model include the refrigerator defrost heater DA47-00244U and the refrigerator temperature sensor DA32-10104N.
Why it matters
Using RD for a refrigerator-side airflow problem and FD for heavier, system-wide icing saves time and helps you confirm whether the defrost system is working before replacing parts.
