Hartsell W Woodstock , GA February 19, 2018 E68 error code Watched You Tube and followed their lead.Error is code 68 is usually A stuck button, but if not, it is then either a bad circuit board or bad thermostat. I purchased both and will return the thermostat since the circuit board was the problem. Very easy to replace and saved over $200. 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
