My fridge was too cold - everything was freezing solid, even in the produce bins. The air from the diffuser vent was constantly running. After unplugging the fridge and plugging it back in, the diagnostic code on the control panel indicated that the air diffuser was not working. I purchased a new air diffuser, watched the very helpful video that showed how to install it, and replaced the part in about 10 minutes. The next day, I can tell that everything in my fridge has finally begun to thaw out. So happy! This part saved me from spending $1500 on a new fridge. Thank you, Appliance Parts Pros!
