The two screws that hold the transformer in place are not identical: one is a regular silver screw and the other is a yellow/brass screw that doesn't have a slot for a screwdriver and must be removed and reinserted using a nut driver. Figure 5 of the installation instructions says: "During reassembly, Ensure that one of these screws is yellow."
