Replaced main control board. New exactly what it was. Kept coming up with code E-68. Heater & thermostat was fine.Ordered from appliancepartspros.com. Cheaper then eBay & Amazon had what I wanted in stock. Sent to me. Had it less than 2 days at my doorstep. Took front control panel off and installed new less then 10 minutes, and was fixed. If your not familiar with the front loader dryer unit. Can take longer but is pretty easy if you follow directions.
