What year is my Kenmore dryer model?
For Kenmore dryer model 11086873800, the exact manufacture year comes from the serial number, not the model number alone. We date it by decoding the serial tag (usually on the door opening or inside the door area) and matching the serial format used for this Kenmore-built-by-Whirlpool style dryer.
Look for the model and serial tag, then write down the full serial number exactly as shown.
- Open the dryer door and check the door opening (cabinet front)
- Check the inside of the door itself
- Check the rear panel if you do not see a tag up front
- Record both the model and serial numbers before ordering parts
We use the serial number to identify the production date. On many Kenmore 110-style dryers, the serial number format includes a date code that maps to a specific year and week/month of production.
| What you have | What it tells us | What to do next |
|---|---|---|
| Model number (11086873800) | Product family and configuration | Use it to find correct parts and diagrams |
| Serial number | Build date (year and week/month) | Decode the serial to get the exact year |
The build year helps confirm the correct version of parts when a design changed mid-production (common with wear items like a drum belt, idler pulley, or door switch). If your dryer squeals, will not tumble, or will not start, the right part match prevents repeat repairs.
If you are troubleshooting while you date the unit, these are frequent replacements for this model family:
- Belt 341241 (no tumble, burning rubber smell)
- Dryer idler pulley WP691366 (squealing, belt slipping)
- Dryer door switch W10820036 (won’t start when door is closed)
- Motor 279827 (hums, won’t run, intermittent start)

Where is the part number on a Kenmore dryer?
On a Kenmore dryer like model 11086873800, the model and serial tag is usually on the door opening (often on the frame just inside the door). Once you have the model number, we use it to look up the correct part number for the exact component you need.
- Open the dryer door and check the front frame around the opening
- Look along the left or right door jamb area
- Check the back panel of the cabinet if you do not see a tag in the door opening
- For some builds, the tag can be near the lint screen housing area
Most people say “part number,” but there are two different numbers that matter:
| What you need | What it’s used for | Example for this model page |
|---|---|---|
| Model number | Identifies the exact dryer version so we can match parts | 11086873800 |
| Part number / part ID | Identifies the replacement part itself | Belt 341241 |
- Write down the full model number exactly as shown (all digits)
- If the tag is worn, take a clear photo and zoom in
- Match the symptom to the part category (no heat, no start, squeal, thumping)
- Use the model number to confirm fit before ordering common wear items like a belt or idler pulley
Kenmore dryers often have multiple versions that look similar. Using the correct model number (like 11086873800) prevents ordering a belt, motor, door switch, or thermal cut-off that does not fit your exact dryer.

What is the average lifespan of 11086873800?
A Kenmore dryer like model 11086873800 typically lasts 13 years with normal household use and basic maintenance (good airflow, clean lint path, and stable power). Keeping wear parts in good shape helps the dryer heat, tumble, and dry efficiently over its full service life.
- Airflow and venting: restricted venting overheats components and shortens life.
- Lint buildup: lint in the chute, blower housing, or ducting increases heat and strain.
- Load size: frequent overloading stresses the drum support, belt, and motor.
- Heat cycles: high-heat drying all the time accelerates wear on heating and safety parts.
- Electrical condition: loose connections can cause intermittent operation and damage.
If the dryer still has a solid cabinet and drum, replacing a few common wear parts often restores reliable operation:
| Symptom | Common wear area | Example part for this model |
|---|---|---|
| Drum not turning or squealing | Drive system | Belt 341241 |
| Long dry times, weak airflow | Blower and lint path | Dryer blower wheel WP694089 |
| Thumping, belt slipping | Tensioner | Dryer idler pulley WP691366 |
| Won’t start when door closes | Door switch/strike | Dryer door switch W10820036 |
- Clean the lint screen every load; wash it monthly to remove residue.
- Check and clean the vent run; keep it short, smooth, and not crushed.
- Avoid overloading; dry similar fabrics together for shorter cycles.
- If drying slows, inspect the lint chute and blower area for buildup.
- If you see heat damage or smell hot wiring, stop using the dryer and inspect the terminal connections.
Most “old dryer” failures are airflow or wear-part issues, not the cabinet itself. Good venting and timely replacement of drive and airflow parts reduce overheating, improve dry times, and help your Kenmore 11086873800 reach its full 13-year lifespan.
