My dryer is not shutting off or even registering the clothes are dry when using the sensor settings. Am having to use the timed dry. Could it be that the sensor bar needs to be replaced?

Steve for Model Number MDE7657BYW

ANSWER Hello Steve, You need to check the exhaust duct and clear the restriction. If the timed dry works, the only thing that will prevent the auto dry cycles from working properly is a lack of air flow. I get lots of arguments about this but think of it like this: When the hot moist air cannot exit the unit, the sensors continue to sense the same moisture and the timer never advances. If you want to test this, remove the exhaust duct from the back of the dryer and start it on an auto dry cycle. You will see the timer advance within 5 to 10 minutes. If the sensor bars were bad, the timer would advance all the time because it would never see the moisture and the timer would cycle without ever stopping.
