How to find discontinued appliance parts?
For Oster model 940-08-A (kitchen center power unit with grinder/pureer), the fastest way to find discontinued parts is to search by the exact model number and any numbers printed on the old part, then cross-check for compatible substitutions or “new old stock” listings. We focus on matching fit and electrical ratings so the replacement works safely.
- Find the model tag and confirm the model is 940-08-A.
- Remove the part and write down every marking: part number, molding numbers, and any voltage/amp ratings.
- Search using multiple formats: the full part number, just the numeric portion, and common name (for example, “drive coupling” or “switch”).
- Compare photos and measurements (mounting holes, shaft shape, connector style).
- If the part is electrical, match ratings (volts, amps, wattage) and terminal type.
- Our model-based parts lookup and search tools on Sears PartsDirect.
- “New old stock” (NOS) and used parts listings (verify condition and return policy).
- Appliance parts recyclers and local repair shops that keep older inventory.
- Compatible or superseded parts (same function, same fit, same ratings).
| What to match | Why it matters | What to look for |
|---|---|---|
| Mounting and fit | Prevents vibration and misalignment | Hole spacing, tabs, bracket shape |
| Shaft/coupler geometry | Ensures power transfers correctly | Flat spots, splines, diameter |
| Electrical rating | Prevents overheating and failure | VAC, amps, wattage |
| Connector style | Avoids loose connections | Spade size, plug type |
Discontinued small-appliance parts often have look-alikes that do not fit or do not meet the same electrical rating. Verifying fit and ratings up front prevents repeat failures and protects the motor, switch, and wiring.

Is a vacuum cleaner considered a small appliance?
Yes. In most household and retail categories, a vacuum cleaner is considered a small appliance because it’s a portable, plug-in device used for everyday home cleaning, similar to other countertop or handheld electric appliances.
Small appliances are typically:
- Portable (not permanently installed)
- Powered by electricity (corded or battery)
- Used for routine household tasks
- Easy to store in a closet, cabinet, or on a shelf
- Serviced by replacing common wear items (cords, switches, filters, belts)
Most upright, canister, stick, handheld, and robot vacuums fall under “small appliance.” Some edge cases can be labeled differently depending on the seller or service category.
| Item type | Common category label | Notes |
|---|---|---|
| Upright/canister/stick vacuum | Small appliance | Most common classification |
| Handheld vacuum | Small appliance | Often grouped with small cleaning appliances |
| Central vacuum system | Built-in/home system | Typically treated as installed equipment |
| Commercial shop vacuum | Tool/equipment | Often categorized with power tools |
Category labels affect how parts are organized and searched. If you’re looking up parts for an Oster 940-08-A kitchen center power unit with grinder pureer, it’s also listed under small appliance parts, even though it’s a kitchen device rather than a cleaning device.
- Use the exact model number when searching parts lists
- Match the product type (vacuum vs. kitchen center) to avoid wrong-fit parts
- Check for common wear items first (filters, belts, cords, switches)

What is the average lifespan of 940-08-A?
Most Oster kitchen center power units like model 940-08-A last 10 to 15 years with normal home use and basic care (cleaning after use, not overloading the grinder/pureer, and storing attachments properly).
- Motor load: forcing tough ingredients or running the grinder continuously shortens motor life
- Heat buildup: long run times without breaks can overheat the motor
- Cleaning habits: moisture left around the drive hub or switches can lead to corrosion
- Cord condition: repeated bending near the plug or housing can break internal wires
- Attachment wear: dull grinder parts make the motor work harder
- Run in short bursts; let the motor rest between batches.
- Keep vents clear; wipe the housing with a lightly damp cloth only.
- Dry all removable parts completely before reassembly or storage.
- Stop using it if you smell burning or hear grinding; inspect before the next use.
- If performance drops, check for dull or jammed attachments before assuming a motor problem.
| Usage pattern | Typical lifespan | What you usually notice first |
|---|---|---|
| Light (occasional) | 12 to 15 years | minor noise increase, slower grinding |
| Normal (weekly) | 10 to 12 years | intermittent power, worn attachments |
| Heavy (frequent, long runs) | 7 to 10 years | overheating, switch issues, cord wear |
A kitchen center power unit is motor-driven; most “end of life” failures come from overheating, worn electrical connections, or overworked attachments. Matching your use habits to the motor’s limits is the simplest way to reach the 10 to 15 year range.
