yep, find the leak. If it's not a line out by the compressor, it's going to be the evaporator which would mean new fridge time if it's not easy to get to the leak point. The condensors almost never seem to go bad. If it doesn't say how much refrigerant it takes, you can kinda "wing it" by vacuuming it down, plugging it in, and then add refrig until it turns on and runs. Then just add a bit more (excess will pool up in the evaporator core) and leave it be. What you don't want is to add so much that it's fluid coming back into the compressor. An icing evaporator can also cause that. You could take this time to add an inline sight glass. In that case, just add refrigerant until it's not bubbly in the sight glass.
If they can get you asking the wrong questions, they don't have to worry about answers.
