Dryer will not start and displays F26 (motor drive system error)

Safety First: Unplug the dryer. Moving parts and live circuits can be hazardous.

• Check drum movement: With the dryer unplugged, open the door and try to rotate the drum by hand. It should turn smoothly. If it is very hard to turn, inspect for jammed items or seized rollers.
• Access motor: Remove the front panel and drum (if necessary) to access the drive motor and blower wheel.
• Inspect blower wheel: Check for foreign objects in the blower housing and ensure the blower wheel spins freely and is not cracked or rubbing.
• Check wiring: Verify the motor harness connector is fully seated and wires are not burnt or loose.
• Motor test: With the motor removed or isolated, test motor windings for continuity according to the service sheet values. An open winding indicates a bad motor.
• Relay check: Inspect the main control board for a burnt motor relay. If the relay is visibly damaged or does not click when starting, the board may need replacement.
• Replace components: Replace the drive motor or main control board as indicated by testing. Ensure the correct Whirlpool part numbers are used.
• Reassemble and test: Reinstall the drum and panels, restore power, and run a cycle to confirm the motor starts and F26 is cleared.
