Not knowing for sure that the problem was the capacitor, I was reluctant to purchase and replace the part. I went AppliancePartPros.com web site and clicked on the part replacement video.The repair video was short and well illustrated. Before the repair began, the service rep says, " the reason you would replace the capacitor is that after turning the timer on, the machine would just hum." The instruction video was the reason that I purchased the part at AppliancePartPros.com The part was indeed cheaper at AppliancePartPros.com but even if it was a few dollars more than other parts places, I would've used AppliancePartPros.com. because of the video. It was well done, informative with the correct replacement diagnosis. Thanks AppliancePartPros.com.
