Which side is the suction side of a compressor?

The low side, or suction line, will be the line connected to the compressor from the top or higher position. It will be cold to the touch and may be wrapped with insulation. This is where freon enters the compressor as a gas.

What is the low side pressure of a refrigerator?

The low side on a refrigerator only will run around 15 psig. If a freezer/Refrig, it will run around 1–5 psig. High side can vary from as low as 100 to over 175, depending on ambient temps and condenser design.

How do you identify a suction line?

How do I know if my refrigerator compressor is low on Freon?

How do you check refrigerator refrigerant pressure?

What happens when Freon is low in refrigerator?

An insufficient supply of Freon indicates that there is a leak in the system. If the leak is not repaired, the Freon gas will continue to leak. Freon (R-12) is a hazardous gas and inhaling the gas can cause respiratory difficulty, burns, brain damage, or even death.

What happens if you put too much Freon in a refrigerator?

A refrigerant overcharge alters the pressure inside the air conditioner and puts the compressor in danger. The Compressor: Excess refrigerant creates a danger called slugging. … Eventually, slugging will cause complete compressor motor burnout—and that often means the whole AC must be replaced.

Will a refrigerator compressor run without Freon?

Yes. A compressor can run without refrigerant, but they are not designed to do so and they will quickly overheat. Compressors employ an internal thermal cutout. This is the last line of defense against a compressor burnout.

Why is my refrigerator not cooling enough?

Problem: Fridge Not Cooling

Be sure the fridge is plugged in and getting power. … Vacuum the coils under or behind the fridge. Clogged coils can cause poor cooling. Check to make sure nothing is stuck in the condenser fan and that it spins freely (models with coils on the back won’t have a fan).

How long does Freon last in a refrigerator?

Never. Actually, Freon lasts forever. The only reason you would need more of it is because of a possible leak. Since the said refrigerant is circulated through copper refrigerated lines to keep your humble abode cool and keep the heat away, it stays inside the air conditioning unit, forever.

How does a side by side refrigerator work?

After doing a bit of research I discovered how these side-by-side refrigerators work. Cool air flows from the refrigerator side into the freezer compartment and back into the refrigerator. The flow of air is controlled by an air diffuser located in the wall between both compartments.

Is a fridge colder at 1 or 9?

Interior Knob Controls:

The coldest setting is “9” and the warmest setting is “1”. The “0” setting is OFF, which turns the cooling off. Turn knobs to lower numbers for warmer temperatures and to higher numbers for colder temperatures.
