Robert E Omaha , NE January 28, 2017 Hold to start tab was broken on interface assembly I determined that the start tab was broken on the Interface Assembly by drilling a large hole in the Hold to Start button making it necessary to replace it as well. After watching the YouTube video on replacing the Interface Assembly a couple of times to familiarize myself with the procedure and feeling comfortable that I could do the job, I ordered the parts. The Control Knob was previously broken and needed to be replaced so I ordered the Control Knob, the Hold to Start button and the Interface Assembly. Our Duet gas dryer is stacked on top of the washing machine and it took longer to unhook the dryer gas line and get the dryer off of the washing machine than it did to complete the washing machine repair. I completed the repair and had everything put back together and the dryer stacked on top of the washing machine in about 45 minutes. The instructional video on YouTube was very informative and made the repair easy. I did break some of the the locking tabs off the old Interface Assembly due to them being brittle but didn't care as it was being replaced anyway. The repair was not difficult and I'm confident I saved $200-$300 by doing it myself, especially since the dryer had to be taken off the top of the washing machine. Time means $$$ plus the cost of a service call and mark-up on the parts. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
