How To Diagnose A Choking Car Compressor?
If you are experiencing problems with your car's air conditioning, the compressor may be to blame. The compressor pumps refrigerant through the system, and if it is not working correctly, you will likely notice a decrease in cooling power.
As a leading service provider, Southgate Ford will discuss how to diagnose a choking car compressor.
How Does A Compressor Choke?
The compressor has a certain amount of pressure that it can handle. If this exceeds, the compressor will start choking and operating inefficiently.
A compressor can choke for several reasons:
- The belt may be loose or broken, which causes the pulley to slip as well as insufficient airflow through your condenser coil.
- Overheating of suction gas or ambient conditions at the higher side, which increases the pressure ratio between low and high sides, thereby choking the compressor.
Signs of a Choking Compressor
Loss Of Cooling Power
The first sign is loss of cooling power - your car's air conditioner may not be blowing cold air. There are several reasons this could happen, and they can all be dangerous to the compressor if ignored for too long.
Blocked Condenser
Your compressor may choke if the condenser is blocked by dirt or debris in front of it. This reduces airflow through the condenser, which results in overheating.
Mold or Mildew
Mold or mildew has accumulated in the evaporator of the air conditioning system. This inhibits heat transfer and also creates a foul odor when you turn on your car's air conditioner.
Low on Refrigerant
The compressor is low on refrigerant, which often happens due to leaks in the A/C system. The result is that it takes longer for the compressor to cool down. The compressor will make noises when it is running due to increased vibration.
No Lubrication
Another reason for a choking car compressor is if it was not properly lubricated. This often happens when the compressor is new and needs to be broken in with mineral oil before you can use it in your car's air conditioning system.
To diagnose this problem, check whether or not there are leaks around any of the hoses that connect to the A/C system.
If you suspect your car's A/C system might be suffering from one of these problems, don't wait until summer arrives before getting it checked out by a trusted mechanic.
