What's the lifespan of a bottom freezer fridge?
Most bottom-freezer refrigerators last about 12 to 15 years with normal household use. For your Samsung RF28HFEDTSR, lifespan depends most on condenser airflow, door seal condition, and how well the ice maker and defrost system stay clear; our RF28HFEDTSR owner's manual covers the care steps that help maximize service life.
A bottom-mount (bottom-freezer) refrigerator’s life is mainly driven by compressor run time and heat removal.
- Condenser cleanliness (dust and pet hair raise operating temps)
- Door gasket sealing (warm air leaks increase run time)
- Ice maker health (clogs and freezing issues can create extra load)
- Room temperature and ventilation (tight cabinets shorten life)
- Power quality (surges can damage control boards and motors)
Use this simple schedule to extend life and reduce breakdowns:
| Task | How often | Why it helps |
|---|---|---|
| Clean condenser area and ensure airflow | Every 6 months | Reduces compressor stress |
| Check door seal for gaps, tears, or warping | Every 3 to 6 months | Prevents warm-air infiltration |
| Keep vents inside compartments unblocked | Ongoing | Maintains even cooling |
| Replace water filter on schedule (if equipped) | About every 6 months | Protects water flow and ice production |
These symptoms often show up more frequently as a unit ages:
- Compressor runs almost constantly or struggles to restart
- Temperatures swing (food spoils faster, freezer softens)
- Excess frost or recurring defrost problems
- Water leaks or puddles that keep returning
- Ice maker stops producing reliably
A refrigerator that’s working harder than it should uses more electricity and can warm up during heavy use, which risks food safety. Preventive care keeps the sealed system (compressor and evaporator) from being overworked.
For ice-related issues that can shorten lifespan, follow why your Samsung fridge stopped making ice and how to fix it.

What is the difference between force defrost RD and FD?
On Samsung refrigerator model RF28HFEDTSR, RD is the forced defrost mode for the refrigerator (fresh food) compartment, while FD is a broader forced defrost mode used to run a defrost cycle through the system. These modes are mainly for troubleshooting and service checks; see the RF28HFEDTSR owner's manual for your model’s control steps.
- RD (refrigerator defrost): Targets the fresh food evaporator area to clear frost that can block airflow.
- FD (forced defrost): Runs a forced defrost routine that may be used as a general defrost mode on some Samsung designs.
- Mode order: When stepping through service modes, RD often appears before FD.
- Why you would use it: To address symptoms like warm fresh food temps, fan noise from ice buildup, or restricted airflow.
- Use RD when:
- Fresh food section is warming up but freezer seems normal
- You hear the evaporator fan hitting ice
- Frost builds up behind the fresh food rear panel
- Use FD when:
- You need a more general forced defrost for troubleshooting
- You suspect system-wide defrost issues
- You are following a diagnostic procedure from the RF28HFEDTSR owner's manual
| Mode | What it refers to | What it’s meant to defrost | Most helpful for |
|---|---|---|---|
| RD | Refrigerator defrost | Fresh food evaporator area | Fresh food warming, airflow restriction |
| FD | Forced defrost | General forced defrost routine | Broader defrost troubleshooting |
Choosing the right forced defrost mode helps you melt the frost that is actually causing the airflow problem. That can restore cooling faster and helps you confirm whether the issue is frost buildup (defrost system) versus a failed fan, sensor, or control.
If frost and airflow problems keep returning, common related checks include the evaporator fan operation, temperature sensing, and door sealing. For door sealing issues, the refrigerator door gasket DA97-05253W is a common wear item to inspect.

What is the most common problem with Samsung refrigerators?
The most common issues we see on Samsung refrigerators like model RF28HFEDTSR are cooling problems (warm fridge or freezer), ice maker troubles (no ice, clumping, freezing up), and water leaks from a clogged drain or door seal gaps. Start with airflow, temperatures, and basic maintenance checks.
- Confirm settings: refrigerator about 37°F and freezer about 0°F.
- Make sure vents are not blocked by food packages.
- Clean dust from the condenser area (restricted airflow causes warm temps).
- Check doors close fully; look for torn or loose gasket areas.
- If you see water under drawers, inspect for a drain restriction.
| Symptom | Most likely cause | What to do first |
|---|---|---|
| Fridge warm, freezer OK | Fresh food airflow issue, frost buildup | Check vents, listen for fan, inspect for frost behind rear panel |
| Freezer warm, fridge warm | Condenser airflow issue, sealed system issue | Clean condenser area, verify condenser fan runs |
| No ice or slow ice | Ice maker freeze-up, water supply restriction | Check fill tube for icing, confirm water flow |
| Water pooling inside | Defrost drain restriction | Clear drain path and confirm water flows to drain pan |
If troubleshooting points to a failed component, these are examples of parts on this model that often tie to the symptoms above:
- Refrigerator temperature sensor DA32-10104N (temperature reading issues)
- Refrigerator condenser fan motor assembly DA97-15765A (poor condenser cooling, warm temps)
- Refrigerator door gasket DA97-05253W (warm temps, moisture, frost from air leaks)
- Refrigerator drain cap DA67-01301A (water leaks from drain issues)
Cooling and ice maker complaints often start as simple airflow, dust buildup, or door-seal problems. Fixing those early helps prevent food spoilage, excessive frost, and strain on the compressor.
For model-specific operating details, error displays, and reset steps, use the RF28HFEDTSR owner's manual. For ice maker-specific troubleshooting, follow why your Samsung fridge stopped making ice and how to fix it.
