I have the FUF 14 Upright freezer. The technician left the back panel off. Where does the two seals go on the back panel - on the top and bottom or on the two sides. Secondly, there is a plastic wheel like disc with 8 spokes and 8 holes located at the bottom of the spokes and a hole in the center. Where does this wheel go in the reassembly of the back panel covering the cold control thermostat WR9X544? I have located and ordered one, and plan to install the thermostat myself.
