The fan motor is bad. The fan motor capacitor may also be the problem. First, an amperage test should be done on the motor to see if its exceeding the rated amps. Secondly, the capacitor should be tested for the amount of microfarads it has. If its an old mtor, it should be replaced, along with the capacitor. All of this should be done by a licensed A/C contractor!
when unplug ed and plug ed the power switch relay will make click if supply is in working condition to circuit. so compressor if not working the means no sound then definately it is in problem.
If the compressor in a refrigerator stopped working, the heat transfer cycle would be disrupted because the compressor is responsible for circulating refrigerant and compressing it to remove heat from the interior of the refrigerator. Without the compressor, the refrigerant cannot absorb heat from the interior and release it to the surroundings, resulting in a lack of cooling inside the refrigerator.
An increase in discharge pressure will generally lead to an increase in compressor amperage, as the compressor will have to work harder to maintain the higher pressure. This could indicate that the compressor is working harder and consuming more energy to meet the increased demand. Monitoring compressor amperage can help in understanding the system performance and identifying any potential issues.
A compressor can stop for various reasons, such as a loss of power, a malfunction in the motor or electrical components, low refrigerant levels, or a blocked air filter. Regular maintenance and troubleshooting can help identify and address issues that may cause a compressor to stop working.
Hazards of working with a dynamic balancing machine include entanglement in rotating parts, exposure to high-speed moving parts, risk of electrical shock, and potential for injury from unbalanced rotating objects. Proper training, use of personal protective equipment, and adherence to safety procedures are crucial to mitigate these risks.
Determine what is not working properly, then determine why.
with a new compressor is a good place to look and see if it's working then see if the fan to blow it is still working you fix it with a new ac compressor pulley and recharge the freon in the car
You will have to figure out why: This the 90% of the time failur: Is there Freon in the system, if there is not a minimum pressure, usually 17 PSI, the compressor will not run. Is the compressor and clutch capable of working? Is the fuse in good shape.
working principle of a compressor
the asiest way to see if it is working is to start the car, turn on the a/c, watch your compressor. you should hear a click than the center of the compressor pully will start rotating, if that doesnt happen you could be low in gas in your system, you can always fill it just to check
it might be the air condition gas or most probably the air condition compressor
If its just the compressor that's not starting then it could be bad contactor bad capacitor burnt or broken wire bad compressor lower than normal line voltage If you are not comfortable testing or working with electricity then don't attempt this on your own
Central air conditioning may quit working at night due to various reasons such as a malfunctioning thermostat, clogged air filters, low refrigerant levels, or issues with the compressor. It could also be due to an overloaded electrical circuit or a tripped breaker. It is recommended to have a professional HVAC technician inspect and diagnose the problem to determine the exact cause.
I would start with the basics and look for a blown fuse - there should be a fuse for the air conditioning switches , A/C compressor clutch
The A/C compressor is clutch driven, when electricity is applied to a coil, it engages the clutch. Most likely the coil shorted out in the A/C clutch on the front of the compressor.
Air conditioning systems can stop working for several reasons. The most common reason is that the fluid charge has leaked out. Other causes include a disconnected wire, a worn compressor clutch, a broken belt, a seized compressor, a clogged expansion valve, and the list goes on...
Most likely, your air conditioning compressor is cooked or its pulley clutch has seized. Hopefully it was the pulley, because the compressor is not cheap.
