Do-It-Yourself Story

I have replaced the LG water filter myself for the past 10 years. This time I inserted the filter, did not feel the thread was engaged, I turned the filter clockwise and no water came through the filter. So I figured that the filter head might be bad. I checked with YouTube and learned that to replace the filter head one just have to remove the housing or head, remove the water inline and outline and put it back. I used Google to search "LG water filter housing" (I did not know yet it was called filter head). It came up with appliancepartspros.com. I found the filter head was similar to mine. It costs $47 including shipping. So I decided to order it and gave it a try DIY. The part came in two days later. I turned off water line, removed the filter housing by taking out a holding screw, pulled out the filter head, removed the two plastic tubings. I used vinegar to clean the plastic tubings and coated them with Vaseline to make it easier to insert them. Then I inserted the tubing, one 1/4", one 3/8" to the new filter head, slid the head to a holding screw. Put the housing back. I inserted new water filter and turned it clockwise. I could feel that the head was engaged. I turned on water and there was no water leak at where tubings were inserted. So I know that I have completed the job. The old water head came in with manufacturer might be somewhat defective, because it used to be difficult for me to rotate the filter to remove it and rotate it after the replacement was inserted. With the new one, I can insert the new filter and rotate it clockwise easily.
