How do I know if my Kenmore dryer thermal fuse is blown?
On Kenmore dryer model 11087874800, a blown thermal fuse usually shows up as a dryer that won’t start at all (most common) or runs but won’t heat on some configurations. The sure way to know is a quick continuity test with a multimeter after disconnecting power.
Common symptoms we see
- Dryer won’t start, even though the outlet has power
- Motor hums briefly, then stops (some cases)
- Dryer tumbles but has no heat (less common, depends on design)
- Cycle ends early or clothes stay damp because the dryer never heats
- You recently had restricted airflow (lint buildup, crushed vent, clogged screen)
How we test the thermal fuse (safe, reliable)
- Unplug the dryer (or switch off the breaker).
- Access the fuse (often on the blower housing or exhaust duct area).
- Pull the wires off the fuse terminals.
- Set a multimeter to continuity or ohms.
- Touch probes to the fuse terminals.
What the meter reading means
| Meter result | What it means | What to do next |
|---|---|---|
| Beep or near 0 Ω | Fuse is good | Check door switch, start switch, belt switch, motor, or timer/control |
| No beep or OL/infinite | Fuse is blown | Replace the thermal fuse and correct the airflow problem |
Why it matters (and what to fix at the same time)
A thermal fuse is a one-time safety device; it opens when the dryer overheats. If you replace it without fixing the overheating cause, the new fuse can blow again.
- Clean the lint screen and housing
- Inspect and clear the vent duct to the outside
- Confirm the outside vent hood opens freely
- Avoid long, crushed, or kinked vent runs
- Don’t run the dryer with the lint screen missing

How do I tell what model my Kenmore dryer is?
Your Kenmore dryer’s model number is printed on the appliance’s ID tag; once you find it, match the full number exactly (letters and digits) when ordering parts or troubleshooting. For this page, the model number is 11087874800.
Where to look for the model number tag
Check these common locations on Kenmore dryers:
- Inside the dryer door opening (on the door frame or cabinet front)
- On the back panel of the dryer cabinet
- Around the lint screen housing area (near the filter opening)
- On the side panel edge near the door opening
- On the lower front area behind a small access panel (some designs)
What the model number looks like (and why it matters)
Kenmore model numbers are usually a long string of numbers (sometimes with a prefix like 110). Using the exact model number helps us show the correct diagrams and parts for your dryer, such as the belt 341241 or the dryer valve coil kit 279834.
Quick ID checklist
- Copy the model number exactly as printed
- Also write down the serial number (helps with production version)
- Take a clear photo of the tag before it wears off
- Use the full model number, not just the first three digits
Model number vs. serial number
| Item | What it tells you | Used for |
|---|---|---|
| Model number | The exact dryer design and parts fit | Parts lookup, diagrams, repair help |
| Serial number | Production run details and date coding | Confirming revisions, service history |
Why it matters
A single digit difference can change the drum support, door switch, or gas burner parts that fit. Matching the model number first prevents wrong-part returns and speeds up repairs.

What is the average lifespan of 11087874800?
A Kenmore dryer like model 11087874800 typically lasts 13 years with normal household use and basic maintenance. Keeping airflow strong (lint screen and venting) and replacing wear parts as needed helps this dryer reach its full service life.
Typical lifespan and what affects it
Most dryers fail early due to heat and airflow stress, or due to drum-drive wear.
- Heavy loads and frequent cycles shorten life
- Restricted venting overheats components
- Running with a slipping belt strains the motor and idler pulley
- Gas ignition parts wear with age on gas models
- Regular cleaning reduces breakdowns and drying time
Maintenance that extends life
These steps make the biggest difference for a Kenmore dryer:
- Clean the lint screen every load
- Inspect and clean the vent duct regularly (short, smooth metal venting is best)
- Avoid overloading; it stretches the belt and stresses drum supports
- Listen for squealing or thumping and address it early
- If the drum stops turning or slips, replace the belt 341241 before it damages other parts
Common wear parts and what they do
| Symptom | Likely wear area | Example part on this model |
|---|---|---|
| Drum will not turn, burning smell | Drum drive | Belt 341241 |
| Squealing, slow drum start | Tension support | Dryer idler pulley WP691366 |
| No heat on a gas dryer, intermittent ignition | Ignition system | Dryer igniter 279311 |
Why it matters
A dryer near the end of its lifespan often shows longer dry times, more noise, or intermittent heat. Fixing airflow issues and replacing a low-cost wear part early can prevent bigger repairs like a motor replacement.
