Replace a Spare part Receiver drier – a defective one or if the limit of use has been already reached. Find out useful information about Receiver drier
Faults of receiver/dryer
corrosion;
mechanical damage;
clogging and contamination of the receiver;
wear of the filter element.
Symptoms of receiver-dryer faults
lack of control over airflow temperature;
the noise in the air conditioner pipeline.
Causes of receiver-dryer faults
depressurization of the system;
damage to O-rings and plugs;
freezing of hoses in the winter season;
absorbent chemical reactions with the compressor products;
improper refrigerant refilling procedure;
excessive or insufficient cooling agent amount in the system;
overheating of the system;
compressor failure;
use of low-quality refrigerant;
clogging of intake pipe.
Diagnostics
The receiver-dryer analysis begins with checking the refrigerant level in the system. If it is below normal, the entire pipe is checked for leaks. A special indicator is added to the agent that can be seen under ultraviolet light, so the diagnosis requires a source of light in that range.
The intake hose is checked in case of low the receiver throughput. Its inner diameter is 0.3 mm so ingress of even very small foreign particles could bring the receiver out of order.
Check the part outlet temperature. If it is cold to the touch, it is necessary to clean the receiver from dirt.
The receiver service life is about 5 years. It is directly dependent on the operation conditions of the entire air-conditioning system. Lack of maintenance can reduce it by several times. Diagnosis should be irun at least once a year or every 40 000-50 000 kilometers.
Repair and replacement of the receiver/drier
After 1.5-2 years of service it is necessary to replace the receiver filter element. It's quite simple, but requires special tools to work with Freon.
After removal of the cooling agent it is necessary to disconnect the receiver, remove the cover with the locking ring. If you cannot remove the filter, an incoming hole of the pipeline can be fed with compressed air. Remember that the filter element must be in a sealed package. Its maximum capacity is up to 50 ml of water, a resource that will last for 2 years, provided there is no damage to the pipeline.
