After reading other posts, I learned that "tO" meant that the thermistor was open. Also, I read that this part would bench test with a multimeter correctly but could still malfunction in the dryer. FIRST UNPLUG DRYER. After checking all of the exhaust ducting including inside the dryer for any blockages that could result in an overheating problem I decided to order a new thermistor. To replace thermistor: First, there are two screws at the rear top that you remove and the top tilts up and comes off. There are four screws on the top front that removes the front control panel. Next remove the screws at the top of the dryer, two screws in recesses behind the door and tilt front forward while unplugging the door switch. Lift and remove front with door attached. Remove screws from exhaust duct and slide down and out. Thoroughly clean inside of duct and fan blades. Clean out any other lint build up. Locate thermistor to the right of duct, unplug and remove two screws. Replace with new part and reassemble while not forgetting to plug the door switch back in. At the rear of dryer, remove screws around exhaust duct and remove. Dryer will have to be slid away from wall about three feet to remove duct from inside dryer. Clean thoroughly and check/clean and check for blockages in ducting from dryer to outdoors. Re assemble making sure rear duct engages the front ducting properly.Plug dryer back in and enjoy.
