Lg 3920DD3005A Door Gasket OEM Part

Pulled out the old gasket. Then, found the middle of the new one and started in the top middle of the dishwasher and pushed the new one in and worked my way to the left and down the side and then the right and down the side. It did not seem long enough at first as it did not curve under at the bottom like the old one. I took it out and measured against the old one and it was a little shorter. So, I started again at the top middle and then pulled it taut as I worked my way around and down both sides tucking in the gasket. This worked great and gave it the proper length to wrap under the side bottom, like the old one. Problem solved.

Gasket replacement was diagnosed by a technician and then I easily installed it. / Before that I had replaced the vent fan assembly, which internet had said was most common reason for this model leaking small amount from left bottom corner of door

Bought a new seal, pulled out the old seal, and pushed in the new seal. It was very easy to replace. It took only a few minutes.

Removed the old gasket (it was coming apart). Cleaned the gasket retaining pocket and the surrounding area. Installed the new gasket by pressing into the slot (remember the orientation of original gasket - lip/flat pointing inward). Work it into place by pushing it into retaining slot. Then recheck to see it is all the way in.
