My clothes dryer seems to be on the blink. Just looking for some feedback before I call in the repairman to see if I may be able to fix it myself. When you turn it on it runs for about 5 minutes then shuts off. Saturday I pulled it out from the wall, cleaned under and behind it. Shopvak'd inside the back of it and double checked that the vent hose was clear and not all jammed up. No matter what I did, it still does the same thing. Anyone else had this happen before?
