![]() Once compressed, the freon is in a volatile, high-pressure state. The compressor is powered by a serpentine belt, which provides the energy needed to compress freon refrigerant to cool the car's cabin. ![]() Replacing Your Car's AC CompressorĪt Advance Tire Company we recommended that car owners replace the complete AC compressor assembly because the compressor replacement core operates under extreme physical pressure. Call today at 61 and talk to one of our pro mechanics about repairing your car's AC compressor. ![]() A cracked or damaged compressor can cause your car air conditioning to fail. Do you need assistance inspecting the state of your ac compressor in your vehicle?Ĭall Us today ! We have automotive ac specialists near you.At Advance Tire Company we know each component of your car's AC has a specific function. Without refrigerant to move the oil, the auto ac compressor may not be properly lubricated and compressor lock up may result. The car engines in vehicles with the clutchless compressors should not be run without refrigerant in the A/C system. Low Refrigerant charge and electronically controlled compressor lock up ? An inefficient ac condenser will cause an auto ac compressor to lock up. Inefficient ac condensers and air conditioning compressor lock upĭebris on the condenser will affect the desuperheat, condensation and subcooling processes happening in the auto ac condenser.AC condenser with bent or missing fins will be unable to efficiently operate. Air and moisture inside the system will create excessively high operating pressures and temperatures and eventually could lead to a compressor lock up. Improperly replacing any component in the automotive air conditioning system where the system must be opened for replacement of the damaged part and not evacuating the system before recharging it with the proper amount and type of refrigerant will contaminate the ac system with air. The use of excessive Dye to help finding leaks in the ac system could create a contamination problem as well, increasing the normal working pressure of the ac compressor and the overall efficiency of the air conditioning system. The contaminated components must be replaced. Sealer can’t be removed from the A/C systems. The use of sealers to fix small refrigerant leaks will cause oil and refrigerant contamination and ultimately ac compressor lock up. Anything more than the correct type of freon and oil is a contaminant. AC compressors lock up due to ac system contaminationĪuto ac compressor damage may occur because of system contamination. ![]() Most compressor lock ups are the result of a lubrication problem. An undercharge or overcharge refrigerant condition will increase the air conditioning compressor temperature and a change in oil viscosity and lubrication characteristics. Refrigerant moves the oil inside the ac system and helps to cool down the ac compressor. SAE J2788 requires charge accuracy of +/- one-half ounce.Īttempting to charge by cans is History !! Car ac compressor lock up due to improper compressor lubrication. Being off as little as 2 ounces can cause problems.R-134a and R-1234yf ac system tolerances require charge rates that must remain or should be charged within +/- 5% of OEM recommendation. Modern auto a/c systems require super accurate charging. Inaccurate refrigerant(freon) charges increase the chances of auto ac compressor lock up. ![]()
