How to replace Assy Pcb Main;Orca,Dryer Main,120V/60Hz,. Ordered the part and fixed it, very easy to remove the control board. Total time to take out and replace was probably 20 minutes. With the new board all is working right. Would have had to pay $85 for a service call from Sears. Saved a lot of money by doing this one myself!! Ordered the part on Sunday and had it by Wednesday. Appliancepartpros.com is a very easy site to use and I would say they did a great job. Found the part on a few other sites, and one was a little cheaper. But shipping was going to take a lot longer. It is not fun to be without a dryer so we picked the faster alternative! Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
