I have a washer and dryer stacked on top of each other in a fairly tight closet, see picture below. Due to a couple electrical boxes on one side of the closet, I am unable to slide the units to the side to access the back of the closet. By climbing on top of the stack I can see that the water hoses are too short to slide the whole unit out of the door, as suggested in this question: How to move stacked washer/dryer from closet
There does appear to be enough dryer vent and electrical cord to move just the dryer all the way out of the door.
I have verified that the dryer will come free of the washer by removing a couple screws on the front of the unit.
I'm not strong enough nor large enough to move the 127 lbs of dryer by myself, and due to the space restrictions of the closet I can't see how to get another person in the space to help me with the lift. Additionally, the width of dryer is 27" while the width of the door at the smallest point is 29.5" which means it would be impossible to carry the unit out the door and have your arms wrapped around the side of the unit.
What is the easiest method of removing the dryer from the top of the washer for servicing? What tools or devices are recommended to help safety remove the dryer?
