Thank you for submitting a question to Manage My Life. I know how frustrating it can be when appliances do not function properly.
The model number you gave me is incorrect. Here is general information about the "AF" error.
"AF" flashes if a restricted airflow condition exists; meaning that 3 consecutive cycles were run with airflow less than 19CFM (cubic feet per minute). Check to make sure the lint screen is clean, the door seal is securely in place and the vent is not obstructed. Also check the drum seals for air leaks. NOTE 1: Error code can be cleared by pressing the Drying Temp pad for 5 seconds while in stand-by mode. AF will flash in the display for 1 second then "on" will appear in the display. Press Drying Temp again and "of" will appear in the display. NOTE 2: Press "start" to turn the blocked vent detection display off. F30 will still be stored in the EEPROM.
If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
