How do I know if my Kenmore dryer thermal fuse is blown?
On Kenmore Elite dryer model 11087872603, a blown thermal fuse commonly shows up as a dryer that won’t start at all or runs but won’t heat. The only reliable way to confirm it is to unplug the dryer and test the fuse for continuity with a multimeter.
Quick symptoms to watch for
A blown thermal fuse can look like other problems, but these are the most common signs:
- Dryer won’t start (no motor run)
- Drum turns but there’s no heat
- Cycle starts and then stops quickly
- Burning smell or very hot cabinet (often from restricted airflow)
- Repeated “no heat” complaints even after checking cycle settings
How we confirm the thermal fuse is blown (continuity test)
Use the steps in the 11087872603 manual for safe access and disassembly guidance.
- Unplug the dryer (or shut off the breaker).
- Access the thermal fuse (typically on the blower housing or exhaust path).
- Pull at least one wire off the fuse terminal.
- Set a multimeter to continuity or ohms.
- Touch probes to the fuse terminals.
- Good fuse: continuity tone or near 0 ohms
- Blown fuse: no continuity (open circuit)
Helpful part reference
If you confirm the fuse is open, use the exact replacement listed for this model: dryer thermal fuse WP3392519.
Why the fuse blew (and what to fix so it doesn’t happen again)
A thermal fuse usually opens because the dryer overheated. The most common cause is poor airflow.
| What to check | What you’re looking for | Why it matters |
|---|---|---|
| Lint screen | Film or heavy lint | Restricts airflow and raises temps |
| Vent hose behind dryer | Kinks, crush points | Blocks exhaust |
| Outside vent hood | Weak airflow, stuck flap | Traps heat and moisture |
| Blower area | Lint buildup | Reduces air movement |
Why it matters
The thermal fuse is a safety device. Replacing it without correcting the airflow problem can lead to another no-heat or no-start situation and can overheat other components like the heating element or thermostat.

How much does it cost to replace idler pulley on dryer?
Replacing the idler pulley on a Kenmore Elite dryer model 11087872603 typically costs $200 to $350 when a service technician does the work; the job usually takes 30 to 60 minutes. If you’re doing a DIY repair, your cost is usually the part(s) plus basic supplies.
What affects the total price?
Several factors change the final cost, even for the same Kenmore Elite 11087872603 dryer:
- Labor rates in your area and minimum service-call charges
- Whether the drive belt is worn and replaced at the same time
- Whether drum support rollers or other wear items are also noisy
- If the dryer needs extra disassembly due to installation (tight closet, stacked setup)
- Whether you choose DIY vs. professional repair
Parts commonly replaced with an idler pulley
On this model, a squeal or chirp often points to the idler pulley, but it can also be belt or roller wear. If you’re already opening the cabinet, it can be cost-effective to replace wear parts together.
Quick comparison: DIY vs. service call
| Option | What you pay for | Typical cost range |
|---|---|---|
| DIY | Parts (and your time) | Often under $100 depending on what you replace |
| Professional repair | Parts + labor + service call | Commonly $200 to $350 |
Why it matters
The idler pulley keeps proper tension on the drum belt. When it wears, the belt can slip, squeal, or eventually break, leaving the drum unable to tumble and potentially causing additional wear on the motor pulley and drum support system.
Helpful reference for this model
For safety steps and basic dryer care that can reduce wear (like keeping airflow strong), use the 11087872603 dryer manual.

How to hard reset a Kenmore dryer?
For Kenmore Elite dryer model 11087872603, the most reliable “hard reset” is a power reset: unplug the dryer (or switch the breaker off) for 1 minute, then restore power and try starting a cycle again. This clears many temporary control glitches without disassembly; see the 11087872603 use & care manual.
Hard reset steps (model 11087872603)
- Press STOP/CANCEL twice to end any active cycle.
- Unplug the dryer (or turn both dryer breakers off if it is hardwired).
- Wait 1 minute.
- Restore power.
- Press POWER, select a cycle, then press and hold START for about 3 seconds.
If the dryer still will not start after a reset
These checks are especially important on this electric Kenmore Elite model because the drum can sometimes turn even when heat or full power is missing.
- Confirm the dryer has 240V power; many homes use two fuses/breakers for the dryer.
- Make sure the door is fully closed and the latch engages.
- If the display shows PF (power failure), press and hold START to restart.
- If the dryer starts then stops or will not run, a safety device may have opened.
Common part-related causes (and what they affect)
| Symptom | Likely area | Example compatible part for this model |
|---|---|---|
| Won’t run at all | Overheat safety opened | Dryer thermal fuse WP3392519 |
| Runs but no heat | Heater circuit issue | Dryer heating element WP8544771 |
| Stops due to overheating | Airflow restriction or over-temp protection | Whirlpool dryer thermal cut-off fuse kit (352-degree f) 280148 |
Why it matters
A true power reset is fast and safe, and it helps us separate a one-time electronic “glitch” from a repeatable problem like restricted venting, overheating, or a failed heating component.
