Reasons for Frequent 5-Second Cycling of Car Compressor

[LucilleDella]

Reasons for frequent 5-second cycling of car compressor are as follows: intervention by the car air conditioning's energy-saving mode. The energy-saving mode operates similarly to a household refrigerator. When its self-checked temperature reaches the set target, it automatically shuts off the compressor to cease operation, achieving energy-saving effects. When the temperature rises beyond the set range, it restarts to bring the temperature back on track. Many Japanese cars feature this energy-saving mode, which is a normal phenomenon and not indicative of compressor issues. High discharge pressure and low suction pressure. Presence of moisture in the system can cause pipe blockages or ice jams. These can be resolved by flushing the pipes with high-pressure nitrogen. Internal blockages in the expansion valve may also affect intake and exhaust pressures. Insufficient or excessive refrigerant. The amount of refrigerant directly determines system pressure, and abnormal pressure can lead to frequent compressor cycling. The above explains the reasons for frequent 5-second cycling of car compressors.
