1. Make sure that the 3-hr Air-fluff/Wrinkle Prevent option is not on.
2. Run a light load of clothing. Does it heat?
If the unit does not cut off and runs continuously unplug the unit for about 5 minutes and plug back in if it’s turning then we need more details about if the unit is heating or not.
