What causes an air conditioner compressor to fail?
What causes an air conditioner compressor to fail?
Two common problems will wear out or kill a compressor: excessive pressures or lack of oil. Lack of oil is the most common cause of failure. Lack of oil is caused by either: A low level of oil related to refrigerant loss over the years. As the refrigerant escapes from the system the oil is carried out with it.
What to do if your Porsche air conditioner is not working?
Make sure your ignition is off. Apply 12 volts to the coil side of the wire (that’s the wire lead that goes to the compressor side of the circuit). The front clutch hub should move or snap into the clutch pulley. If it does then chances are your clutch coil is OK.
What causes a Porsche air conditioner clutch to slip?
Clutch turns but slips. If the front hub on the compressor seems to “slip” (we are not discussing the belt here) you could have two potential problems: The air-gap between the faces of the front hub and pulley is too large. This does not happen often on it’s own, more probably if the compressor was overhauled.
What happens if there is no oil in the air conditioner compressor?
Since the compressor relies on the refrigerant to carry the a/c oil to it for lubrication, a lack of refrigerant will reduce the amount of oil to the compressor. Without oil the compressor will lock up. Compressors are simply “pumps” with closely machined tolerances.
Can a malfunctioning AC compressor cause a problem?
The heat of summer can be intense, and the worst thing that can happen is finding yourself with a malfunctioning HVAC compressor. A working AC will provide you with nice and cold air as opposed to bearing the brunt of warm, dry air. With how much the HVAC runs, something is bound to go wrong with its compressor.
How can I tell if my compressor is running or not?
Not really. DIY kits come with a low pressure side gauge and they’re designed to provide a static pressure (engine not running or AC off) and a running pressure. Static low side pressure won’t give you any idea of system charge. You could have a low side target range of 50-psi and see that static pressure on your gauge.
What should I do if my compressor clutch is not working?
If you’re not getting battery voltage, pull the compressor clutch relay and check for power and ground on the relay control coil terminals in the socket. Wiring varies by make, model, and year. Some car makers trigger the relay control coil ground through the PCM or ECM.
Make sure your ignition is off. Apply 12 volts to the coil side of the wire (that’s the wire lead that goes to the compressor side of the circuit). The front clutch hub should move or snap into the clutch pulley. If it does then chances are your clutch coil is OK.
