An AC system has many components: compressor, condenser, receiver dryer, evaporator, and hoses. The compressor, the “heart” of the car’s air conditioning system works like a pump taking refrigerant, ( R-12 Freon in older cars, R-134a in 1995 and newer cars) and pressurizing it, passing it along to the evaporator. The AC compressor has several moving parts (including pistons and valves). These internal parts can fail, causing the AC compressor to stop working. It is common for the internal parts of the compressor to come apart and disperse metallic debris throughout the system. Consequently, it is a requirement to replace the orifice tube and the receiver dryer when replacing the compressor since some of the debris may have ended up there. 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 remanufactured 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.Keep in mindThis service comes with receiver dryer and orifice tube. It is very common for metals from the compressors to go throughout the system and get caught in different components. If the compressor is replaced without the dryer and the orifice tube, it will ruin the new compressor and it will not be covered by the warranty from parts manufacturers.

The A/C does not cool without a working compressor, and the compressor does not function properly without a working A/C compressor clutch. In order to properly diagnose and fix problems associated with an A/C compressor clutch, consumers should develop a basic understanding of how the system works.

Otherwise, they could spend time and money purchasing the wrong parts when they could have conducted some simple A/C compressor clutch diagnostics. The A/C compressor is essentially the working core of a vehicle's A/C system. ac unit smells like moldWhen consumers turn on their A/C units, the A/C compressor starts to compress refrigerant in the system. rv ac repair tampaThis compression creates high pressure and raises the temperature of the refrigerant before it enters the A/C condenser. samsung air conditioner window 1 ton priceThe A/C compressor clutch is in charge of alerting the compressor to start this compression. In other words, the compressor clutch is responsible for communicating to the A/C compressor when to start and stop operating.

The A/C compressor clutch actually has multiple components. Once the A/C system activates, the compressor clutch pulley starts to rotate the compressor clutch hub, which is a round metal piece located at the front of the clutch. The compressor's belt rides along the pulley. The compressor clutch hub attaches to the compressor shaft, which starts to rotate, creating both suction and discharge. The compressor's belt then forces the compressor clutch pulley to rotate, and that causes the compressor clutch coil to pull the hub against the pulley. The compressor clutch coil is tightly wound copper wire found below the pulley that acts as an electromagnet. These combined actions allow the A/C compressor clutch to engage the compressor and turn on the A/C. A lot of common A/C problems originate with the A/C compressor and the compressor clutch. However, before jumping to any conclusions, consumers should attempt to rule out any issues that could merely require simple fixes. If the A/C blows only moderately cool air when the temperature setting is at the coldest, owners can check a couple of things.

First, they need to ensure the cooling fans on the A/C radiator and A/C condenser work properly. They also need to look for debris that might be blocking the A/C condenser and keeping cold air from passing over it. Finally, consumers should check the cabin air filter to ensure it is free of debris and contaminants. Although a completely non-working A/C system could certainly indicate a serious problem, sometimes another culprit exists. Consumers should examine A/C systems to determine that no breakers or fuses have tripped or blown because those issues prevent power from running through the A/C system. A/C compressor clutch problems regularly occur when routine maintenance does not take place on the vehicle's A/C system. As a result, the A/C compressor clutch is often to blame for common A/C problems. Suction pressure is too high Discharge pressure is too low Compressor delivers inconsistent pressure to the refrigerant Addition of a shim to close air gaps between the hub and pulley Replace A/C compressor clutch

If A/C compressor has voltage, probably defective compressor clutch Replace A/C compressor clutch A/C compressor clutch coil receiving inadequate voltage Overheating of internal winding Slippage of hub against the pulley A/C compressor clutch may have a defective pulley bearing With regards to most of these issues, the best solution is often to replace the A/C compressor clutch. However, qualified technicians are sometimes able to replace or fix individual components within the A/C compressor clutch. eBay has a wide selection of A/C compressor clutches and its components for purchase from a variety of reputable sellers, including clutches and related parts made by top brands like AC Delco, Motorcraft, and Four Seasons. Search for the exact A/C compressor clutch part you need and then narrow down your search results by price, condition, or even the location of the seller. Before making a purchase, be sure to check out eBay's deals on car and truck parts to see if you can find what you need at the lowest possible price.
