Sherry N Puyallup , WA February 27, 2015 Appliance: Model DLEX3470V The main control board went out Our LG dryer would not stop running. We had a company come out to fix the dryer, and they gave us an estimate of $425.00. They told us it was our main control board which would cost $280.00. And it was on back order it. We went on the internet and found AppliancePartsPros.com and the same part was $135.00. We saw a video on utube how to install it, very simple. Order the part did it ourselves and it cost us a total of $142.00 which included shipping. Saved a bundle. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
