This is a multi-use and multi-appliance screw. It can be used on a microwave, refrigerator, range/oven, air conditioner, dehumidifier, washer, or dryer. The measurements of this screw are 8 x 1/2 inch...
Removed all screws from the outside case, then I had access to the motor. Removed 4 screws from the bracket holding the motor assembly in place, removed it from the case. Next I pulled off the broken fan part, installed the new blade and secured it with the supplied bracket. Next I installed the motor assembly in reverse with the 4 screws I removed earlier. I made sure the blade would move freely, no wire in the way. Also, when you remove the motor assembly you will have to remove the motor wires from their attachment points, but is easy, they are just "plugged" in. In any case I recommend you make a small drawing/schematic as to where the wires go for proper hookup later. The last thing is to put the case cover back on, line up the holes and insert the screws you removed earlier. The unit has been running like new now!!
(1) Compared old an new motors to ensure compatability. (2) Removed old motor from frame. (3) Mounted new motor to frame. This was the easy part...took a couple of minutes. The tricky part was the wiring--because of how the original motor had been wired into the appliance, I ended up splicing the new motor wires into the old motor end-clips (left them connected the whole time)...took over half hour. Now if I can only figure out a way to keep the fan from working out along the shaft and hitting the radiator, I will be very happy (this seems to be annual repair).
