your condensor is clogged up, or your condensor fanmotor is not working, or your compressor struckup due mechanical problem inside of your compressor.
Compressor terminal amps refer to the electrical current measured at the terminals of a compressor motor, indicating how much current the compressor is drawing during operation. This measurement is crucial for assessing the compressor's performance and ensuring it operates within its rated specifications. High terminal amps can indicate issues such as overloading, voltage problems, or mechanical failures, while low amps may signal inefficiencies or improper functioning. Monitoring terminal amps helps in maintaining the efficiency and longevity of the compressor system.
The starting amps for a 4-ton AC compressor typically range from 20 to 50 amps, depending on the specific model and manufacturer. This high inrush current, known as the "starting current," is significantly higher than the running amps, which usually range from 10 to 20 amps. It’s important to check the compressor's nameplate or manufacturer's specifications for the exact starting amp rating. Additionally, factors like the system voltage and design can influence these values.
It could, the computer will disengage the ac compressor if the engine temp is too high.
High voltage and low resistance would cause high amps. E = I R or I = E/R. PS E would be electromotive force measured in volts. R would be resistance measured in ohms. I would be current flow measured in amps.
Compressor problems but sounds the opposite of what the symptoms are usually. Repace compressor and check for leaks. Compressor problems but sounds the opposite of what the symptoms are usually. Repace compressor and check for leaks.
Was the voltage to the compressor clutch checked? Not knowing how thorough the under-hood check was, it sounds as if the compressor is not engaging. The causes for that are varied, but it is an electronically controlled event.
Inside an air conditioner compressor is a motor with two windings: a high-current coil called Start, and a low-current coil called Run. Both windings are connected to each other at a junction, aptly called the Common terminal.
A high-pitched noise from your home air conditioner compressor could indicate several issues, including a failing capacitor, loose components, or a refrigerant leak. It may also be related to the compressor itself struggling to operate properly. It's important to address this issue promptly, as ignoring it could lead to further damage or system failure. Consider contacting a qualified HVAC technician to diagnose and resolve the problem.
The electric fans used to cool the engine are designed to switch on to full speed when the air conditioner compressor is being used. When you turn on the heater/defroster the air conditioning compressor also turns on to help remove moisture from the air. Since both when heating or cooling your car the air conditioner compressor is working the fan will be running at high speed and makes more noise.
On any automotive A/C system there is one basic rule. The line that leads from the compressor to the interior of the vehicle is always the Low side. The line that runs from the compressor to the front of the vehicle is always the high side.
It's a cycling clutch compressor. It disengages to keep system pressure where it should be. When it reaches the high point, it disengages. Then it engages again when it reaches the predetermined low point.
Too much refrigerant can do it, yes. System pressures get extremely high on both sides of the AC system when it is overcharged.
