Mark M for Model Number WTW5550XW0 During the sensing mode, the washer will spin and stop twice, which is normal. The third time, it starts to spin and the motor hums very loudly and will not stop humming unless unplugged. The tub does spin, but slowly. I have run the diagnostics and both fault & error codes say "motor control fault'. Looking further (page 16 of service tech manual) says a faulty capacitor may cause the motor to 'hum', not start or turn slowly. I am confused by a prior question on this page where you said it WASNT the capacitor. I do not have an ohm meter. When running thru every item on the manual and automatic test mode, each function works! I guess I was hoping it was the capacitor and not the main control board.
Answer Hello Mark. With it working sometimes and not others, it does not sound like the capacitor. However, it could be a weak capacitor causing the issue. Try replacing it and if the issue continues, replace the board. Read More... Answered by AppliancePartsPros.com | Friday, October 10, 2014
