Appliance Parts Pros saved the day once more. I found the defective part via the exploded part posted on Appliance Parts Pros web site. They even had a video for the repair. I used a hair dryer to melt the ice and dry the freezer section. The part swap took thirty seconds.
A big thank you to Appliance Parts Pros again. I have been using them for the past ten years: their instruction videos are wonderful, their prices are awesome, their website and exploded parts diagrams very useful, they always have the original parts available and the packaging is flawless, nothing comes broken . They are so reliable and real pros.
