How to Troubleshoot & Replace Lg AP4635690 / 5040JA2004A Rear Evaporator Motor Grommet

First let me say not only were the prices of the parts great. But they also arrived lightning fast. Rather than just replace the motor. I ordered the fan motor, fan and all related parts as well as the grille panel. Since I was not sure whether I could remove the old grille panel without breaking it or not. I was correct I broke a corner off the old panel as I removed it. While I had the panel off I used a hair drier to defrost and dry off the evaporator coil. After that is was simply a matter of removing the old fan assembly. Then assembling the new fan motor, dampers, motor bracket and fan and attaching the assembly to the new grill panel. Then reinstalling the panel, drawer track and drawer. The only hard part to the repair was removing that drawer and drawer track. Only removed one side of the draw track to clear enough room to remove grille panel. I refrigerator now is working perfectly it is now so quiet I barely even hear it running. 

I had to replace the Defrost Sensor and the entire fan assembly. I purchased everything just so I had every part I needed. The Fan Assembly took less than an hour to replace. I had previously replace the Defrost Sensor so I already knew the steps to access the Fan Assembly. The videos are extremely helpful, step by step procedures. NO surprises 

I replaced the fan , motor and support .plus found the condensation drain tube clogged .gave it a goodly cleaning . the nose and odor went away .the parts came in the mail within 2 days perfect timing to make it a week end job.took about 2hrs. 

Remove all shelves and bins out of refrigerator and all shelves and bins out of freezer to remove center back Center duct assembly to replace blower motor remove glass out of shelf and replace outer support reinstall all parts parts fit just like original good quality 

I installed replacement motor and grommets. After figuring out this was the most likely cause of the problem, I watched a couple of videos. I didn't find any videos featuring a fridge like my 2003 model, but I was able to figure out my way back through the freezer compartment with trial and error until I exposed the old evaporator fan and motor. Tip: pliers can be very helpful for releasing the clips of electrical connectors - I had to unclip several. As soon as I got to the fan, it confirmed that this was the problem: the "propeller shaft" had a huge amount of play as it rotated, causing the fan to rub against the housing as it turned. Sure enough, as soon as I had reassembled the fridge with the new parts, it worked perfectly with no noise. 

Followed the instructions in your videos. However, when it came time to pry off the evaporator cover along the inside-back of the freezer, I initially could release only the right-hand side. I eventually figured out that so much ice had frozen onto the left-hand end of the evaporator coils, that the ice was "glueing" the cover to the coils. I positioned the nozzle of a hair dryer between the base of the cover and the inside-back of the freezer compartment. I blew hot air into the area of the evaporator coils for twenty minutes, to de-frost the coils enough so that the evaporator cover would finally release. Once I had access to what I thought was the faulty fan motor, I discovered that I had ordered the wrong replacement fan. I reassembled the freezer, with the intention of buying the correct replacement fan (now that I had seen and photoed the part number of the old fan). To my surprise, the refrigerator started working correctly (the troublesome fan noise had gone away)! My conclusion: so much ice had built up on the evaporator coils, that it had interfered with the proper operation of the fan. Your videos are excellent!!! 

Read the probable cause for the situation, figuring an evaporator fan was the issue and ordered the grommets. Removed the freezer drawer to access the fan and evaporator coil area. Removed the panel along the back wall and noticed ice build up in corner of coil and encroached into the fan blades. Defrosted the the coils with a hair drier and removed ice, checked the evaporator heater resistance. All ok. reassembled. Didn’t need the parts after all. 

Turned out to be the fan for the ice maker. The fan for the evaporator was next to it so I replaced it also with new rubber mounts. The fans were 15 years old. The fridge works great now. I have replaced the ice maker twice since new in 2007. Very easy fixes, just watch the videos. I have used AppliancePartsPros.com now for about 20 years. 

Ordered new motor, there is only one Philips screw on the front panel, take it out then, the sides of panel they just snap in. When you have front panel off, unhook temperature sensor and motor. The panel will pull out, take 2 Philips screw out, then pull motor out and replace it. 

I replaced the fan and the two bushings, upper and lower. I watched the video on this site that was with the bushing page, very easy. I saved myself quite a bit of money on a technician or new refrigerator.
