Is it normal for a car air conditioner to start and stop frequently every 10 seconds?

It is abnormal for a car air conditioner to start and stop frequently every 10 seconds. A car air conditioner refers to the air conditioning device installed in a vehicle, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. The reasons for a car air conditioner frequently starting every 10 seconds are as follows: 1. The energy-saving mode of the car air conditioner is engaged; 2. The exhaust pressure is too high or the suction pressure is too low, and moisture in the system causes pipe blockage and icing; 3. Insufficient or excessive refrigerant, as the amount of refrigerant determines the system pressure, and abnormal pressure can cause the compressor to start and stop frequently; 4. The relay setting limit is too high.
An air conditioner that starts and stops every 10 seconds is definitely abnormal. Normally, a car's air conditioning compressor starts and stops based on changes in the cabin temperature, with intervals ranging from a few seconds to several dozen seconds. A 10-second cycle is too frequent and usually indicates insufficient refrigerant or a leak, causing the system to automatically shut down due to insufficient pressure. It could also be an issue with the electrical control components, such as a burned-out relay or a malfunctioning temperature sensor, causing the compressor to mistakenly believe the target temperature has been reached. If you notice weak cooling performance and difficulty lowering the cabin temperature while driving, it's advisable to check the refrigerant level and wiring connections as soon as possible. Delaying repairs can lead to compressor overheating and damage, resulting in more expensive repairs. Additionally, such excessive cycling of the air conditioner increases fuel consumption, making it both uneconomical and unsafe.
