Does the unit have a manufactures process stub on the compressor casing. That is where I put piercing valves to add refrigerant. Remember that EPA does not allow piercing valves to remain on system and the hole it forms has to be brazed shut. So if it does have a process stub place the peircing valve close enough to the end so you have enough stub to pinch off to braze thehole shut.

If there is no process stub, then install piercing valve in a convenient location in the suction piping and pierce the line. Remove the refrigerant and install a "tee". On one leg of the "tee" install a schreader valve pressure tap and rebraze the joints. Perform and pressure and vacuum test to check for leaks and weigh in the correct amount of refrigerant. Once your proficient at this procedure, it should take about 60 to 90 minutes depending on obstructions around compressor.

Just a comment, low air flow on evaporator give that same indications as a low charge. Make sure the evaporator fan is working and you have good air flow through evaporator section.
Hope this helps

Hi, do you still have the parts? I just got a SR-4433S and I think it's missing some of the basic interior stuff like the crisper drawer, etc. I'll figure out all of what I need if you email me back and still have it: m_perlik@hotmail.com

3 way valve charging procedure


On the data plate there is the amount of freon and it's type. Usually F22. There is a tube connected to the compressor that looks like it's going no where. You need a piercing valve to attach to this tube. Evacuate the system for several hours. Add the freon. Use a pinch off tool to close off the tube between the piercing valve and the compressor. Remove the valve and use an acetylene torch and silver solder to close the end of the tube, NO other type of solder besides silphos is acceptable. Remove the pinch off tool and turn on the refriferator

Freon valve location on a sr-4433s sanyo compact refrigeraior


There are generally no service valves on refrigerators. Unlike car A/C refrigerators are designed NOT to leak so need no "recharge" If you are leaking freon you must have the leak fixed. A temporary service valve is attached after the repair is complete, charge is brought up to spec and then valve is removed and the tube it was connected to is soldered shut.

I have a True GDM10 that won't cool. Motor runs normal, Evap fan is running, no ice build up, just won't cool. Is this a coolant problem and can a True GDM10 be recharged? See no hook ups in t


First let me ask, are you sure the compressor is running? If you verified that it was running by vibrations in the compressor area just know that the condenser fan can also cause those if your machine has one. The way to tell is if the compressor is generating heat. With that said, assuming that the compressor is running, and all applicable fans are running, you need to determine if the machine was losing cool over time or did it happen overnight? If the latter of the two you'll need to isolate where the leak is, be it the evaporator or the compressor area. To actually add freon to the system if no access ports are available you;ll need to get a piercing valve, I personally use pt# bpv-31 bullet piercing valves.

Where do you get tap to add freon


I always get my tap valves at www.apdepot.com. The best ones to use are bpv-31 bullet piercing valves, because they are capable of piercing a variety of line sizes, so your not limited to your tap location and find the most accessable spot.

I HAVE A 5 CU. FT. FREEZER AND IT NEEDS FREON. I DONT SEE A FITTING TO INSTALL THE FREON WERE AND HOW DO I PUT THE FREON IN?


Hi, most chest type freezers do not come with service valves to add freon. Why, don't know but its frustrating to me as a commercial Refrigeration Contractor. If you are sure you have a leak, and you know its low on charge, check the data plate to see what freon it takes. Most older models have R-12. Some are 134-A, and I have had some that are R-404A. If your lucky, it will be the 134-A that you can buy at any auto store. When I come across a unit like this, I have what is called a bullet piercing valve or saddle valve that is attached to the suction line of the unit. It is a 2-piece valve that has adapters to fit lines from 1/4" to 3/8" lines. You can find ones for larger lines. They are held on with 3- Allen head screws tightened down evenly so they don't leak when you pierce it. It has a 1/4 " fitting for a service tech's manifold gauges. Your problem would be if it is 134-a, is the hose kit will not fit the valve, as they are made to fit a auto fitting. I know they sell adapters at refrigeration parts houses to convert these to fit, but you need to be a contractor. If you have a Grangers any where near you, this will be your best bet to get both the saddle valves, and the adapter you will need. If you had any way to get a regular service manifold set, that would be a plus. I know this will be your hold up, that and freon if its not the 134-a. Anyway, thats how its done by installing a bullet piercing valve. Once its clamped on the line, the larger of the 2 coming off the compressor, there is a set screw in the center of valve. With hose attached, screw the set screw down to pierce the can. Now, once it is down, it will not flow until you turn the set screw back the other way. When you know you have enough, turn it back to shut it off. Remove the hose and put the supplied cap on the valve. Thats how its done. I wish you the best of luck.

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,

Please do Rate the solution, if you think this helps you,

Concerned.

Everything works on the unit but it does not get cool


You can purchase a bullet piercing valve port to install the refrigerant your unit takes. Refrigerant is available; however, some are much more expensive than others and it is necessary to use the exact type of refrigerant your unit was designed for. The prices of R12 and R22 are astronomical. If your window unit uses either of these two refrigerants, you would be well advised to invest your money in a new unit rather than repair what you have.

Though this is probably not news you wanted to hear, I hope the information is very helpful to your decision-making, moving forward. :-)
