THANK YOU 

Removed the lower back panel, pulled blade from motor and just pushed the new blade onto the small motor shaft. 

Installed a new fan it was a snap. 

Off old, on new. 

I had never used this website before but I have to say they are now my go to people for parts. I checked around for prices on what I needed and they have the best prices and fastest shipping. I received my part the next day (I choose the 10.95 shipping) and was completely satisfied with my purchase. The part I ordered was actually better quality than the one on my fridge! 

Perfect fit...easy to replace. Used nut driver to remove back cover. Thank you for next day service...! 

Upon cleaning the cooling coils, we discovered one of the condenser fan blades had broken off. Replacing the fan was quick and easy, saving us thousands in potential replacement costs. 

PULLED OFF OLD FAN AND REPLACED WITH NEW. 

I ordered the part, it got here early, and I replaced the fan without incident. 

Very easy repair, the old fan pulled right off and I pushed on the new one. Took about 5 minutes. This is the third appliance I've repaired with parts from Appliance Parts Pros, always the right part with fast shipping, and the how-to videos always help.
