Problem: Diagnostic code: Motor circuit failure—open winding or failed start capacitor
How to Fix Dryer Error
- Enter diagnostic mode and run motor test cycle—note if motor hums but won’t start (capacitor) or remains silent (open winding).
- Unplug dryer and remove rear panel to access motor WPW
- Disconnect wiring harness from motor terminals.
- Set multimeter to resistance mode and test windings: Main winding (typically terminals 1-
- should read 2-6 ohms; Start winding (terminals 2-
- should read 4-8 ohms. Infinite resistance indicates open winding—replace motor.
- Test start capacitor (typically 5-8 MFD) with capacitance meter—reading below 80% of rated value indicates weak capacitor.
- If capacitor weak but windings good, replace capacitor WP3392519 ($
- .
- If windings open or shorted, replace entire motor assembly WPW
- During installation, verify blower wheel is securely fastened to motor shaft (setscrew tight).
- Reconnect wiring harness ensuring correct terminal assignment per wiring diagram.
- Exit diagnostic mode and run test cycle—motor should start immediately and run smoothly without overheating.
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
