Motor has failed mechanically or electrically — drum does not rotate when the dryer runs. Replacing the drive motor restores tumbling.
Centrifugal switch inside the motor is stuck or contacts are burnt, causing a loud hum with no rotation on startup.
Overheating motor with failing windings trips thermal protection repeatedly, causing the dryer to stop shortly after starting.
Worn motor bearings produce loud rattling, grinding, or squealing during operation; replacing the motor eliminates the noise.
A motor with a defective centrifugal switch fails to close the heater circuit, so the drum spins but no heat is generated.
💡 Pro Tip: Diagnose Your Samsung Dryer Motor Before Ordering
Your part is likely the culprit if you notice any of the following:
⚠️ Dryer drum does not spin or tumble at all
⚠️ Motor hums loudly on start but drum refuses to turn
⚠️ Dryer starts then shuts off after a few seconds and repeats
⚠️ Motor feels excessively hot to the touch after a short run
🔬 Quick bench test: With the dryer unplugged, try turning the motor shaft by hand. If it is seized and will not rotate, the motor has mechanically failed and must be replaced. For an electrical check, reconnect power and measure resistance between terminal 3 and terminal 4 — should read 2.88 Ω; terminal 4 to terminal 5 should read 3.5 Ω. Readings outside these values confirm a failed winding. Also confirm 120 VAC is reaching the motor from the control relay before condemning the motor — absent voltage points to control board DC92-00382A instead.
