Just replaced the Freezer evaporator fan motor, (for the 1st time) . The factory manual, you can find in this site, shows the evaporator unit dropped
then turned upside down & to hang with a wire from top condenser. I don't know about YOUR copper tubing skills , but if you force the tubing you will
more than likely get a kink. I just dropped it far down enough to get a screw driver in between & rested it on the top shelf. Yes it was hard but i am used to working
blind or limited visibility. Even then I had to be careful in putting it back in. Keep in mind where all the wiring plugs go & how they are routed. I have the CD which is
the same as the download at this site. Had it on my iPad , old timers need help these days.
