An error code on the LCD screen of your Maytag Neptune dryer may appear. Examples include “AF,” “F,” or “PF,” followed by a number. If this happens, press the “Power/Cancel” button twice to cancel the current drying cycle. After this, reselect a cycle and press “Start.” If this doesn’t work, you may need to do a full reset on your dryer. First, disconnect the power by removing the plug from the socket. Then, wait 30 minutes. Now, reconnect the power and choose a new drying cycle.
