Hello, I have a Whirlpool Steam Duet dryer, model #: WED9600TA1. It was running fine for 6 loads throughout the day. Then I went to start it with my final load, when I pushed the start button, it made a clicking noise and would not initiate drying cycle. I unplugged for a few minutes, plugged back in and tried it again. Same response. Before I spend money on a repairman, I'd like to know what it could possibly be and if it's even worth repairing as I've had for 15-16 years. Thank you.
