Understanding the Problem
If your Whirlpool WED75HEFW0 dryer refuses to start or the drum doesn't turn while the motor hums (or is silent), the cause is commonly a failed drive belt, a seized idler, a faulty motor/start switch, or an open door switch or thermal cutoff. These dryers are direct-drive designs: a single motor turns the drum via a belt and idler. When one component in that drive path fails, the drum stops turning while the dryer may otherwise appear to have power. Diagnosing the problem requires a few safe checks: verify the dryer is receiving 240V power (for electric models), confirm the door latch is closing and the door switch is working, listen for motor humming, and inspect the belt and idler for breakage or slippage. Many issues are quick DIY fixes (belt, idler, door switch); motor or control failures may require more advanced work or replacement parts.
Common Symptoms
Dryer has power (lights/controls work) but won't start tumbling; motor hums or clicks; drum won't turn; dryer runs but no tumbling; sometimes a burning smell if belt is slipping.
Common Causes
- Broken or stretched drive belt
- Seized idler pulley or worn drum support/glides
- Faulty drive motor, start switch, or door switch

Helpful Repair Tip
Open the dryer door and try to turn the drum by hand. If it spins freely, the belt may be broken. If it won't turn and you hear the motor hum when starting, the idler or motor may be seized.
Frequently Asked Questions
How do I tell if the belt is broken or the motor has failed?
First unplug the dryer and manually rotate the drum. If the drum spins freely with no resistance, the belt may be broken. If the drum resists turning or doesn't move and you hear the motor hum when you try to start the dryer, the motor or idler pulley may be seized. A burned electrical smell, loud grinding, or visible belt damage confirms belt or pulley failure.
Can I safely replace the belt or idler myself, and how long does it take?
Yes — replacing the drive belt or idler is a common DIY repair if you are comfortable unplugging the appliance and removing the front or top panel. With basic hand tools it typically takes 30–60 minutes. Always disconnect power first and follow a step‑by‑step guide for your exact model. If the motor needs replacement or if you see electrical/control issues, consider a professional technician.
