How to Troubleshoot & Replace Lg AP4439003 / 4986ER0004F Gasket

Reviewed repair videos for replacing the gasket assembly and the door lock switch assembly. Seemed easy enough to do. Had some problems identifying the exact parts for my LG front-load washing machine on the website, so I called the number and spoke with someone at Appliance Parts Pros. They confirmed that the parts I thought I needed were in fact the right replacement parts for my washing machine so I ordered both parts over the phone. Received them in 2 business days with normal shipping. Took about an hour to replace both parts (door gasket must be partially removed to replace door lock switch assembly anyway). The parts replacement were exactly as shown in the instructional videos. It would definitely be easier to re-install the spring loaded bands that hold the gasket in place with the spring expansion tool, but I managed okay with needle-nose pliers and screwdrivers. Needed a second person for the outer spring loaded band without the spring expansion tool. All in all, very happy with the price of the part and the results. Door now works just fine (no dE errors); no more smell from mildew stains on the door gasket; and no more leak from the small tear in the door gasket. I would definitely use AppliancePartsPros.com in the future. 

I replaced the door gasket because I started finding mold. With the help of the online videos on Appliance Pros website replacing the gasket was super easy. So much so that I ended up removing the washing drum from machine so I could clean the inside. Now no more smell!! Thanks for the videos guys!! 

Ordered new gasket. Gasket arrived in 2 days, watched a how to on YouTube and it all went smooth, saved a lot of money doing it myself. 

My problem was a broken spider. I followed your excellent video, but have some additional input that should be incorporated in a new video showing the required upgrade procedures and parts required to repair an early model with damaged front tub half using currently available parts. Don't expect everything to go as easy as the video. 1) Used 4lb. brass hammer to drive shaft from bearings. 2) Torqued spider bolts to 20ft lbs. with thread locking compound. 3) attached rubber seal to front tub cover before attaching the balance weights. Do like the video says and use vise-grips. 4) The new required heating element has the thermistor mounted to it with nonmatching electrical connectors. Had to make a pigtail from the old thermistor wiring harness by attaching two small female blade connectors with crimp fittings. Excellent parts supplier to deal with. Received 12 parts from three different states in four days just before Christmas by FedEx for $7. Thank you, thank you, thank you! 

I started by watching the video and it was very helpful. I would make one suggestion. On our model the weights on the tub sit very close to the front gasket. It is much easier to put the gasket on the tub before you put the weights on. Also, since the washer was tore apart, I replaced the hoses and seals and shocks since the machine is about 8 years old. The shocks made a huge difference. It spins like it did when it was new. Thanks for the video, it was very helpful. 

While I was replacing springs I decided to replace the gasket since I couldn't clean it anymore. Unfortunately that was on back order so I can't fix it just yet. I have taken this LG machine apart already and it is easy to work on. I love all the videos online that go step by step. This repair is simple. I had a difficult time with the spring around the gasket. I think the tool for getting that back on may be worth the $. I would hate to damage the gasket getting the new one on. I called AppliancePartPros when the back order would come. I spoke with a nice and knowledgeable person that told me it was shipping out in two more days. The order came quickly. Great job guys. 

I watched videos on you tube. It was simple. 

Pretty easy to fix, just disassembled the washing machine, disassembled the Outer tub,remove the inner drum replace the spider and reassembled. 

Purchased and installed new door seal. Had to make tool to expand springs during re installation. Repair was easy once I made the correct tool. 

The hardest part of the fix was getting the dryer off of the top. I cannot stress enough how much I appreciate that AppliancePartsPros.com had the 5 top items that cause a leak for my specific model device listed. I decided to get them all just in case and that was a lifesaver. Not only was the cold valve leaking but the dispenser hose also has a bad leak. While I had it apart I replaced everything even if it wasn't bad.
