Googled my appliance model number for problem and indications were the control panel. I identified the part for model WDF510PAYBA. Ordered and Received part promptly and installed myself. Took some thought and effort but I am mechanical and it went in perfectly. Saved $100 by not calling a repair service out. Now all cycles and features are working again. Thanks for the quick service, the right part, and a return policy that made me comfortable if I messed up and ordered the wrong thing.
