Was going to dry a load of clothes on Thursday at noon and dryer Electronic Control Board went poof....F01 Error . I priced a new dryer to match our washer and it was 800.00 ! So I looked up the part @ AppliancePartsPros.com and decided to try to fix it . I Ordered the Electronic Control Board on Thursday late in the evening and the new part was at my front door Saturday morning before noon . I installed the part in less than 5 minutes . My dryer is working just like new, and it was very easy to repair , at a big savings over purchasing a new dryer ! 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
