I have a retreat destination trailer,and I cleaned the air conditioner. The cover that goes over the coils has 3 hinges on the bottom that I couldn't get back on . My question is do these actually have to go back on
We'd need to know the make and model of the AC unit. Do they HAVE to go on? Probably not. Would it be preferable for them to go on? Probably, or why would they invest the cost in adding them?
