The handles are a press fit on the shaft and a heavy hand yanking down to open the door can cause it to rotate out of position. The handle can be re-aligned and pinned in place, as I saw on an old posting here on Stovebolt. I also had some luck in bumping the handle back to its original position while still in the door by hitting it up with heel of my hand. That might work for awhile but if it moves easily back into position it will also move easily back out of position!
