How to Troubleshoot & Replace Lg AP4438221 / 4681JB1029A Evaporator Fan Motor Assembly (Refrigerator)

Unplug. Removed ice bin and support brackets. Removed ice maker and support brackets. Removed top shelf. Removed lamp cover and bulb. Removed rear cover ( 6 tabs ), look for arrows. Removed fan assembly and replaced motor. There are three electrical connectors, ice maker, freezer lamp and freezer fan. 

I replaced the fan motor and reused the old fan assembly. The fan assembly sent was the wrong diameter. It would rub on the side of the opening. 

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. 

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. 

Replaced the freezer fan 

Bought the parts from you and have a repairman come and install the. saved quite a bit of money. pricing matching also helped. will buy again and recommend to others thanks... 

Replaced evaporator motor. Ordered new motor, arrived in two days!!! Great service!!!! I'm a happy, wife is happy!! Once motor is replaced just power cycle to clear error code. 

I replaced the motor with a new one. 

I followed the directions on you tube. very easy and only needed slotted and Philips screw driver. It took 30 minutes and that includes emptying and filing the fridge of all condiments.
