Tip & How-To about Refrigerators

How to add freon to a refrigerator by urself.

You don't need brazing skill or brazing tools to add freon to a refrigerator. And you don't need license to buy it's freon because all refrigerators now a days use R134.
First you will need a line tap which is available at most ac supply. Then you will need a retro fit adapter. available at most auto parts or where they sell automotive ac accessories. Then the freon and charging hose for R134. You would do it as if you are charging an old car with R134. Note that you should use the charging hose with the gauge. If you are handy it is a piece of cake.
One thing to remember is that refrigerators are not air conditions. So the low side pressure is much lower. As you charge it the pressure usually starts at 10psi or less then as the freezer gets colder can be as low as 5psi. Another thing is that it uses much less freon. An indication that it is overcharged is the compressor gets cold instead of getting warm. An indication that it is low on charge is that the compressor gets too hot, and the coils (condenser) do not get warm enough to dissipate heat.

Unless you have a lot of expensive refrigeration tools and a license to recover and buy freon, then you need a serviceman.

how to change a compressor on Samsung refrigerator RS2630SH side by side

Unless you have a license, you'll never be able to buy freon! You'll need a manifold gauge to evacuate and add freon. You'll need to purchase silver solder and an acetylene torch to remove and reinstall the tubing connected to the compressor. You'll have to evacuate the system with a vacuum pump. A specialty tool is needed to access the charging tube on the compressor and another to pinch off the tube once the system in fully charged. You'll need a very accurate scale to add the correct amount of freon. If you have all the tools mentioned here then have at it. I wouldn't suggest trying it if you have no experience with an acetylene torch.

i need to know how and where to add freon

Hello and Welcome to FixYa!
Actually the refrigerant lines of a mini-refrigerator can get punctured; the refrigerant leaks out and the refrigerator seems no longer usable. An appliance repairman is sometimes able patch these punctures and add new refrigerant. Sometimes a compressor will also need to be replaced, which requires removing old and adding new refrigerant. Adding refrigerant to a mini-refrigerator is tricky and should be done by a properly trained technician. A mini-refrigerator cooling system includes a compressor, a condenser and an evaporator.
Things Required:
Refrigerant Refrigerant capture device Vacuum pump PAG oil Instructions:
  • Turn the fridge around and look at the label on the compressor to see what type of refrigerant is used. Most likely it will be R12 or R34.
  • Remove refrigerant with a proper refrigerant capture device, if needed.
  • Locate the access or service valve. This is typically a T-shaped valve. Braze an access valve onto the compressor if one is not already there.
  • Vacuum down the system with a vacuum pump.
  • Screw the refrigerant can valve adapter onto the valve assembly. Attach the charger hose to the suction valve. Put the can in an upright position to keep liquid from leaking into the refrigerant lines. Screw the handle on the top of the valve to pierce the can. Add a small amount of refrigerant. Turn the system on, and continue to add refrigerant in small amounts.
  • Remove, close and cap the can after the refrigerator is properly charged, and add compressor lubricant/PAG (polyalkylene glycol) oil.

I wouldn't recommend you to add the refrigerant at your own, if you are in experienced. This is very dangerous and risky to you and to the surroundings. The successful completion of job requires precise tools and appropriate experience.

Hope this clears the picture, a bit more,

Do you add freon to your indoor unit or your outdoor unit? I have A new 2 ton first co unit indoors unsure what I have outside. Where does the freon go?

I would highly recommend that you get a friend or hire a pro, to deal with this. You dont just add freon, is it -R22 or the new 410A type? You always charge a system from the outdoor unit! If this is a new outdoor condensor, it will be pre charged for the unit, indoor coil and roughly 15 to 25 foot of line set. But after the brazing is done,,, NEVER SOLDERING! You need to use a Vac-Pump and pull the indoor coil and lineset down to 500 microns, before you open the king valves.
If this outdoor unit was used, then does i match the indoor coil? In sizing and type of refrigerant? Need to reclaim the existig refrigerant, pull a deep vacummn on the whole system and then weigh the charge in, according to the tag on the outdoor unit. You should have a CFC license t work with any type of refrigerant, if someone turned you in, it starts with a $ 10,000.00 fine for a start, You need allof the right type of tools and knowlege, save time and money,,,, get a CFC licensed tech,he will know all of this.

refrigetor doesn't freezer

small appliances use CLOSED systems because they use r-12 or 134a freon (you have to be licensed to buy and dispose of it) - once charged - they are sealed shut. You will have to make your own charging port with a tap (similar to a refrigerator water line tap. They are available at most A/C supply shops... however the taps are inconsequential if you do not have a license to purchase the refrigerant.
