Question about Sanyo Refrigerators
Need to add freon and unsure of bullet piercing valve location
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: email@example.com
