No pressure … The recommended pressure for a home refrigerator using R134A refrigerant is between 2 psig and 150 psig. Currently working on an LSXS26386S. Either you have a leak in the system or you have a bad compressor. Most refrigerators built after 1995 typically uses the R134a refrigerant.

Recently installed new Linear … I really appreciate the questionnaire, that actually helps me out a lot. Technically, it is both a motor and a pump, and it looks like a small, often dark-colored cylinder that it is connected to the condenser on one side… Save my name, email, and website in this browser for the next time I comment. R-134a is the most common refrigerant found in automobiles today. I personally now suspect a bad compressor. Lg has been having massive compressor fail rate in units 3-4 years old. Alright folks so we’ve gone over some of the basic facts about R-134a but now let’s take a look at some of the more interesting points about this refrigerant: 1. On the other hand, if you feel like your LG refrigerator water pressure is … The temperature difference varies from one kind of refrigerant to another. As a low-pressure refrigerant system, the R134a is used in most home refrigerators as it is very effective and convenient for high-temperature applications. Is it Worth Replacing a Compressor on a Refrigerator? Agnes is a kitchen and cooking enthusiast as well as a fitness fanatic. These … It can be … If the valve is only allowing a small amount of water through, the water may dispense slowly or with poor water pressure. On a refrigerator, the initial low/high side pressures while it’s running really can’t tell you for sure if it’s a low or high side leak. Having said that, here’s the scoop on system pressures in residential refrigerators running R-134a refrigerant: Low Side: About 2 psig, although I’ve seen these systems pull a slight vacuum, 0 to … Pressure Temperature Pressure Temperature Pressure Temperature psig Degrees F psig Degrees F psig Degrees F (22)-62.38 37 42.00 145 109.4 (20)-55.02 38 43.00 150 111.5 (18)-48.85 39 … The pressure for an ordinarily operating R134a is between 22 and 57 pounds per square inch (PSI). At the lowest temperature, the normal running pressure of the coil is expected to be 22 pounds per square inch. Every Refrigerator have different size of Compressor when we charge Gas then Some Refrigerators Ready on zero (0 PSI) Running Pressure … If the ambient temperature rises or lowers than normal, the pressure changes accordingly. This can be done by reading from the pressure-temperature chart on the refrigerator. Hence, the normal pressure gauge in R134a ranges from 22 to 57 pounds per square inch gauge. I haven't tapped the high side … I'm used to see about 0 psi +or-2 psi in low side… Remember, there are two sides to the chart; we have the low and the high.
