Replace – What is the purpose of  the AC Compressor ? An AC system has many parts that works together or simultaneously , compressor, condenser, receiver dryer, evaporator etc… and hoses. The compressor, is  the “heart” of your home air conditioning system it pumps the refrigerant, (R-222 in older systems , R-410A in ones) and pressurizing hot gas from the evaporator super-heating process.  If it fails it will either be locked LRA WILL BE HIGH or it will simply not pump at all .The AC compressor contains many moving  parts (like  pistons and valves depending on the type ). These internal parts can fail, causing the AC compressor to stop working.

After replacing the compressor you must.

It is a requirement to replace the orifice tube and the receiver dryer after replacing the compressor hence  the debris may have ended trapped in these components. For an AC compressor to work, it needs a clutch, bearing, and an electrical connector. The clutch is driven by a drive/serpentine belt, which engages the compressor when you switch on the AC. The clutch can burn or the bearing can fail. If the bearing or clutch have failed, it is recommended that the compressor be replaced.

Sometimes replacing the entire compressor with a re manufactured one can be cheaper than replacing an individual clutch or bearings. It is also common for the seals in the AC compressor to go bad. The compressor may start leaking refrigerant and/or the AC oil. If the seals no longer hold, you will need a new compressor, as the seals cannot be replaced. A compressor may also fail if there is sludge or debris in the air conditioning system. If there is sludge or debris, the hoses, evaporator, and condenser should be flushed to get rid of the contaminants. When it is not possible to flush the parts, you may need to replace those parts.

Cause of failure.

What is the cause for the compressor failure? The compressor contains the only moving components of the refrigerant circuit, and must respectively be sufficiently supplied with oil. Another task of oil in the refrigerant circuit is compressor cooling in order to avoid overheating. If a compressor is operated with an insufficient amount of refrigerant for an extended period of time (e.g. due to a leak), this results in insufficient heat dissipation and lubrication of the compressor components, as the oil must be transported together with the refrigerant through the air conditioning system.

Due to the excessive operating stress on the compressor components, metal abrasion is generated on the components, which may cause partial or complete blockage of the control valve located on the inside. The control valve blockage results in the compressor not properly working anymore. This damage can only be corrected by professional replacement of the compressor, which also includes flushing of the system. By the way, insufficient lubrication results in damage in all compressor designs.
