How do I know what model my sewing machine is?
On the Kenmore sewing machine model 3851684180, the model number and serial number are printed on the machine’s nomenclature plate. For this model, that plate is located on the back of the sewing machine; we recommend writing both numbers down for parts lookup and service.
Where to find the model number on Kenmore 3851684180
Check these common spots first:
- Back of the machine (primary location for this model)
- On the nomenclature plate (the label that lists model and serial)
- Near the power switch area or lower rear housing (sometimes adjacent to the label)
- Inside or near the free-arm/extension table area (less common, but worth a quick look)
For a diagram and the exact label location reference, use the 3851684180 owner's manual.
What to write down (and why)
When you locate the plate, record both numbers:
- Model number (for this machine: 3851684180)
- Serial number (unique to your specific unit)
- Item name: sewing machine
- A short part description when ordering (example: “foot control” or “needle plate”)
Quick reference table
| What you see on the plate | What it’s used for | Why it matters |
|---|---|---|
| Model number (3851684180) | Finding the correct parts list | Prevents ordering the wrong part |
| Serial number | Identifying your exact unit/version | Helps match parts and service info |
Why it matters
Kenmore sewing machines can look similar across the 385 series, but parts and accessories can vary by model. Using the exact model number from the nomenclature plate helps ensure you get the right match the first time.

How old is a Kenmore 3851684180 sewing machine?
The Kenmore 3851684180 is an older, vintage-era Kenmore 385-series sewing machine. The most accurate way to estimate its age is to use the serial number on the nomenclature plate and compare it to the identification details in the owner's manual; that ties your exact unit to its production run.
Where to find the information you need
To date your specific Kenmore 3851684180, we recommend recording the model and serial number exactly as shown on the machine.
- Look for the nomenclature plate on the back of the sewing machine.
- Write down the MODEL NO. 3851684180 and the SERIAL NO.
- Keep those numbers with your records for parts lookup and service history.
- Use the manual’s diagrams to confirm you are reading the correct plate.
- If you are ordering parts, always use the full model number and part description.
What “385” usually means for age
Kenmore model numbers that start with 385 were produced across multiple decades, so the “385” prefix alone does not give a single year. Your exact age depends on the specific model (3851684180) and the serial number.
| What you have | What it tells you | What it does not tell you |
|---|---|---|
| Model number (3851684180) | The exact design family and parts breakdown | The exact build date by itself |
| Serial number | The best clue to production timing | Nothing without a reference chart |
| Owner’s manual | Confirms features and identification locations | Not always a dated document |
Why it matters
Knowing the approximate age helps us match the right presser feet, bobbin and shuttle parts, needle system, and maintenance needs (cleaning and oiling points). It also reduces ordering errors when you shop by model.
Parts lookup tip
If you do not see the part you need listed for the 3851684180, search by the full model number on Sears PartsDirect to broaden results and compare diagrams.

How do I find out how much my sewing machine is worth?
A Kenmore sewing machine like model 3851684180 is typically valued based on real-world selling prices for the same model in similar condition, plus what is included (case, presser feet, accessories) and whether it sews smoothly. Start by recording the model and serial number, then compare recent sales.
Step 1: Identify your exact machine
Use the model and serial number from the nomenclature plate (the manual shows where to find it). Having the exact identifiers helps you match the right listings and avoid pricing the wrong 385-series variant.
- Write down MODEL 3851684180 and the serial number
- Note what is included: foot control, power cord, case/cabinet, accessory box
- Confirm it runs and stitches (straight, zigzag, buttonhole if equipped)
- Check for missing or damaged items (needle plate, presser feet, bobbin case)
Reference: owner's manual
Step 2: Grade condition the same way buyers do
Condition drives value more than age for most household electronic sewing machines.
| Condition level | What it usually means | Value impact |
|---|---|---|
| As-is / not sewing | Motor runs poorly, jams, or will not stitch | Lowest |
| Working | Sews basic stitches, normal noise | Mid |
| Serviced / tuned | Cleaned, oiled, timed, tension set | Higher |
| Complete / collectible | Original accessories, case, paperwork | Highest |
Step 3: Use comparable sales, then adjust for completeness
When you find sold listings for the same Kenmore model family, adjust up or down based on what you have.
- Add value if you have multiple presser feet and attachments
- Subtract value for missing foot control, damaged wiring, or cracked housing
- Subtract value if it locks up, runs sluggish, or the needle will not move
- Add value if stitches are balanced and fabric feeds evenly
Why it matters
A realistic value estimate helps you decide whether to invest in maintenance (cleaning, oiling, tension adjustment) or put that money toward parts or another machine.
If you decide to repair or replace components, we recommend searching by model number on Sears PartsDirect so you match parts to 3851684180.
