How old is my Amana refrigerator by serial number?
For most Amana refrigerators (including model SBD20NW-P1162503WW), you can estimate the age from the serial number by reading the first 2 digits as the year and the next 2 digits as the week of manufacture (YYWW). That tells you when the unit was built.
How to decode the serial number (YYWW)
Look for a 4-digit sequence at the start of the serial number:
- Digits 1 to 2 = year (for example,
09= 2009) - Digits 3 to 4 = week of the year (for example,
15= 15th week) - Combine them to estimate the build date (year + week)
- The refrigerator is typically put into service shortly after the build date
- If the label is worn, take a clear photo and compare characters carefully
Where to find the model and serial tag
On most side-by-side refrigerators, the rating label is commonly found:
- Inside the fresh food compartment on a side wall
- Near the crisper drawers
- Along the door frame
- Behind the toe grille area (less common)
Quick examples
| Example serial start | Year | Week | Approximate build timeframe |
|---|---|---|---|
| 0915XXXX | 2009 | 15 | Mid-April 2009 |
| 1427XXXX | 2014 | 27 | Early July 2014 |
| 9803XXXX | 1998 | 3 | Mid-January 1998 |
Why it matters
Knowing the manufacture week and year helps us match the right replacement parts and revisions for your Amana SBD20NW-P1162503WW, especially for systems like the ice maker, thermostat, and dispenser tubing.
Parts that commonly depend on the correct model identification
- Ice maker assemblies
- Temperature controls and switches
- Water line fittings and unions
- Fan motors and electrical start components
If you need parts after you decode the date, you can order from the parts list for this model or search by model number on Sears PartsDirect.

How to reset Amana side by side refrigerator?
To reset your Amana SBD20NW-P1162503WW side-by-side refrigerator, we recommend doing a power reset: unplug the refrigerator (or switch the breaker off) for about 5 minutes, then restore power. This forces the control to reboot and often clears minor glitches.
Quick reset steps (power reboot)
- Unplug the refrigerator from the wall outlet, or turn the circuit breaker OFF.
- Wait 5 minutes (10 minutes if the issue is persistent).
- Restore power.
- Wait 5 to 15 minutes for the compressor and fans to restart normally.
- Confirm the interior lights, dispenser (if equipped), and temperature controls respond.
If the problem comes back right away
A reset helps with temporary control issues, but it will not fix a failed part. After the reboot, check these common causes:
- Warm temperatures: condenser coils clogged with dust, blocked airflow, or a door not sealing.
- No cooling but lights work: start components or compressor circuit issues (a run capacitor is a common suspect).
- Ice maker not working: ice maker module or mechanical jam.
- Intermittent operation: loose wiring or a failing door switch.
Helpful parts we commonly see involved on this model include the refrigerator capacitor WPW10662129 and the refrigerator ice maker (red) D7824706Q.
What a reset can and cannot do
| Situation | Reset helps? | What to do next |
|---|---|---|
| Control panel acting “frozen” or unresponsive | Yes | Power reset, then verify settings |
| Brief power outage or flickering lights | Yes | Reset and monitor temps for 24 hours |
| Not cooling, compressor never starts | Sometimes | Check start circuit components (capacitor), wiring |
| Ice maker not producing ice due to a bad module | No | Troubleshoot and replace the ice maker if needed |
Why it matters
A proper reset is the fastest, safest first step for electronic hiccups. It also helps you confirm whether you are dealing with a one-time control glitch or a repeatable failure that points to a specific refrigerator part.

What is the average lifespan of an Amana refrigerator?
Most Amana refrigerators, including side-by-side models like SBD20NW-P1162503WW, typically last 10 to 15 years with normal household use. Consistent maintenance (especially airflow and clean coils) is what most often separates a 10-year fridge from a 15-year fridge.
What affects lifespan the most
A refrigerator’s life is usually limited by a few high-wear systems. These are the areas we focus on first when performance starts slipping:
- Condenser coil cleanliness (dirty coils make the compressor run hotter and longer)
- Door seal condition (air leaks cause longer run times and frost issues)
- Evaporator fan operation (moves cold air through the fresh food and freezer sections)
- Defrost performance (prevents ice buildup that blocks airflow)
- Ice maker and water system leaks (small leaks can create big problems over time)
Maintenance that extends life (simple, high impact)
These steps are the best return on effort for a side-by-side refrigerator:
- Vacuum and brush the condenser area regularly
- Keep vents inside the compartments unblocked
- Clean and inspect door gaskets; replace if torn or not sealing
- Set stable temperatures (avoid “coldest” unless needed)
- Level the refrigerator so doors close fully on their own
Common “it’s wearing out” symptoms and what they point to
| Symptom | Most common cause | What to check first |
|---|---|---|
| Warm fridge, freezer OK | Airflow problem | Evaporator fan, blocked vents |
| Frost buildup in freezer | Defrost or door seal issue | Gasket seal, defrost pattern |
| Clicking, hard starting | Start components | Run capacitor, wiring |
| No ice or poor ice harvest | Ice maker wear | Ice maker module and ejector |
Parts that often come up in real repairs
When troubleshooting aging-related issues on this model, these parts are commonly involved:
- Refrigerator evaporator fan motor WPC8891605 (air circulation)
- Refrigerator thermostat R0161087 (temperature control)
- Refrigerator capacitor WPW10662129 (helps the compressor start and run)
- Refrigerator ice maker (red) D7824706Q (ice production)
Why it matters
A refrigerator that is forced to run longer than normal (dirty coils, air leaks, weak fan) ages faster because the compressor and sealed system stay under higher heat and load. Keeping airflow and seals in good shape is the most reliable way to hit the 10 to 15 year lifespan.

Why is my Amana fridge not cooling but the freezer works?
When your Amana SBD20NW-P1162503WW freezer is cold but the refrigerator section is warm, the problem is almost always airflow: cold air is made in the freezer and must be moved through vents and a damper into the fresh food compartment.
Quick checks (10 minutes)
- Set the fresh food control colder; allow 12 to 24 hours to stabilize.
- Make sure packages are not blocking the supply and return vents.
- Check the freezer back wall for a solid frost sheet (points to an airflow blockage from ice).
- Listen for the evaporator fan in the freezer when the compressor is running.
- Confirm both doors seal tightly and close fully.
Most common causes and fixes
Evaporator fan not moving air
If the fan is weak, noisy, or not running, the freezer can stay cold while the fridge warms. A common repair is replacing the evaporator fan motor: refrigerator motor WPC8891605.
Frost buildup blocking the air path
Heavy frost on the evaporator area can choke off airflow to the refrigerator side. Fully defrosting the unit (unplug and leave doors open) can restore cooling temporarily; if it returns, a defrost-system repair is needed.
Door switch not signaling “door closed”
If the switch fails, the fan may not run as designed. Compare the correct switch for your model, such as refrigerator switch WP10533003 or switch W11384469.
Symptoms-to-cause guide
| What you notice | Most likely cause | What to do next |
|---|---|---|
| Little airflow at fridge vent | Fan issue or blocked duct | Check fan, clear vents |
| Frost sheet on freezer back wall | Defrost-related ice blockage | Defrost, then monitor |
| Fan runs only when switch is pressed | Door switch issue | Test/replace switch |
Why it matters
A warm fresh food compartment can rise above safe food temperatures even while the freezer seems normal; restoring airflow brings both sections back into balance.
