John for Model Number GDF520PGJ5CC This machine appears to be dead. No LED's no response from button pushes. After starting to work on it, it came to life. seemed to be working fine. Could not get it to fail. After several uses it failed again. Before finding your website and good repair help, I replaced the WD21X24901 Main Board from a local parts supplier. That didn't solve the problem. I found your website and asked a question and received an immediate response to test for 13.5 volts on the black/green and yellow/blue wires on the User Interface Control Board. Voltage is there. Machine worked for a couple of days and fail again. I have taken the door apart attempted to clean the connector contacts the best as possible, flexed the entire wiring harness. Before putting additional money into the machine or a new User Interface Control Board, I would like to make sure this will fix my problem. Today I took the non working machine apart again and the first thing I did was unplug the wiring harness on the main board going to the User Interface Board. When I plugged it back in the machine came to life. Can't get it to stop working now. The reason I hesitate to buy the User Interface Board is my concern of the Current Sense Module shutting down the machine due to motor or more expensive problem. Mother-in-law who owns the machine says that ever since it was purchased it would randomly have the LED's come on and make some sounds. She also indicated that even when running on short cycles machine would run for three to four hours. Does it sound like the User Interface Control Board will solve my problem or could it be the Current Sense Module tripping because of another problem? You guys a doing a great job with the quick response and from now on your my supplier for appliances parts!
