  • Summer in 2015, my 13 years old fridge started to not cool enough. So I decided to fix this problem. I did not know what was the main reason for this failure, so I checked many websites as well as youtube videos. What I found was that I needed to check many possibilities for this failure. I cleaned the fridge from bottom to top, then replaced the main control board as well as ice making unit, etc… Non of those worked for me. Then further research, I suspected R-134a ( AKA Freon) thing. So I decided to recharge it. I bought 3 tools. You can buy from ebay or Amazon.
    (I put products links here from Amazon for you !)

    1)Johnsen’s (6312) R-134a A/C Refrigerant – 12 oz.


    2)Supco BPV31 Bullet Piercing Valve


    3)Enviro-Safe R12/R22 Can Tap with Gauge – R-134a Can to R-12/R-22 Port


    Update 11/1/2017


    This is the item to seal and prevent leaks in the refrigeration system. I have not used it, but, from reviews on Amazon seems like it will do the best job. If you use this item to seal and prevent gas leak, please share your experience in the comment section. That will help many viewers in this video as well as people who need to repair their refrigerator. Thank you!

    For me this was first time to recharg R-134a, so my work in the video was kind of in fear and trembling, and made many mistakes.

    From my experience, you want to keep needle of the gauge at around or less 5 psi during the recharging, and keep it slow.

    This video is long and boring if you do not have to fix your fridge, but useful for those who need to recharge compressor with R-134a.

    Always be careful with your DIY project, and I hope you can fix your refrigerator problem too.
