My clothes dryer had an issue and the repairman came promptly. My unit is a tall double apartment-size washer/dryer in a closet-like space. He tore the walls off the entire unit and made a big mess. He did put it back together but when I went to use it, the stainless circular air grill inside the back of the dryer fell off and thumped around with the motion. I checked it and it seems there were NO screws to hold it in place and none to be found nearby. I wasn't reassured when the same guy came to fix it, but it does now work ok.
