OUr dryer has a moisture sensor in it so it shuts off automatically when clothes are dry.I have replaced the moisture sensor bar towards the front of the door and that did nothing to shut off the dryer 1x when the clothes are dry. We now have to run the clothes 3x with the autosensor(not on a timed setting)to get them dry vs 1x when we bought it. I have cleaned the dryer totaly out from lint and the duct work is now cleaned too. After that, it still needs 3x on autodry cycle get clothes dry. Could you please give me an idea what I should do and look for now? thank you very much!
ANSWER Bob, When you replaced the sensor bar, are you sure the wires did not get disconnected or knocked loose or shorted to the chassis. You may want to check the circuit resistance of the sensor circuit at the main control board on the J4 connector. In the wiring harness pin 3 and pin 4(blue wires) there should be an "open" circuit between the wires, place a metal or wet object on the sensor bar and the circuit should "close". Then check each wire to chassis ground, there should be an "open" circuit. If all's OK, recheck the dryer operation and heat with the vent disconnected from the dryer, an average sized/type load should take 35 to 45 minutes to dry if the dryer is heating properly. Otherwise you may need a control board. Good Luck and Thanks
