Lg 3920ED4009B Cam Motor Shaft Seal OEM Part

This was a very simple repair. It was done in about an hour. It involves disconnecting the dishwasher, emptying the water from the inside, taking it out and flipping it over, and replacing the diverter motor. This repair is done on the underside of the dishwasher, nothing to disconnect inside (just remember to remove the baskets). It would be wise to order the motor seal and micro switch that goes with it as they are all cheap parts and easy to swap out during the procedure. Be sure to take pictures of what you disassemble in case you forget how they go back. You will have to reuse the plastic cam from the shaft of the old motor, or you can order a new one (note which side is up!).

I remove the dishwasher laid it on it's backside, took off the bottom panel everything was easy to access. while I had the dishwasher out I just decided to replace the motor as well, I've noticed in the past the motor had been making some abnormal noises.Only reason I knew it was the motor making noise is because I own the same dishwasher, the repairs I just made were on my moms dishwasher, she's owns the same exact dishwasher as I do. After three years of owning my LG I had to replace the motor because it completely went out and it sounded like hers was doing the same. But as for why the drain hose cracked in half that's still a mystery... All in all it has been a decent dishwasher but for the price and the repairs that had to be made on both I won't be purchasing anymore LG dishwashers, but at least LG has made them easy to work on...!! I thank Appliance Parts Pros for offering these parts that were very reasonable priced, the availability, and the shipping options. I will definitely be using Appliance Parts Pros for all my appliance needs and I highly recommend them to anyone.

Replaced the circulation pump and related rubber gaskets, seal and the rubber check valve. Didn't realize how noisy the unit had become until after I replaced the pump. Now we don't even hear it when it's running! Was easy to replace with basic tools, just like the videos. RM

Watched the Video, ordered the Circulation Motor, installed in 30 min. works like a charm. The Video was very helpful Thank You..

Most important lesson: This model has a newer and very different chassis, the underside has a monolithic polyethylene base that is very difficult to remove. The diverter motor is accessible but just barely with an offset wrench. Also, the sprayers are quite different from the video, I could not figure out how to remove them. Note that the LG calls the diverter a Vario motor. I replaced the motor but this did not fix the issue, so I called in the pros. They confirmed that the motor was not the issue, but discovered two round metal punch-outs that were holding the internal plastic valve immobile. Removed the obstruction and the problem solved. This dishwasher includes an elaborate filter system that makes it all but impossible for objects that size to have been washed into the system, so going to file a claim with LG.
