And it no longer circulates refrigerant in your air condition system. When the AC compressor failed, of course, your AC vent will not send cold air inside the car. The responsibility of this part is to convert the refrigerant gas into a liquid as it passes through the condenser. The compressor is an important component of the air conditioning system and without it, your AC can not be able to function. And the last result is that your AC is off at the same time. When the coolant has problems such as leaks, blockages, condensation, or the coolant level is too low compared to the standard, it will cause the cooling process to be interrupted, and the car engine will be too hotter than the standard. The hot water is then cooled by the fan, transported to the tank, and recirculated back to the engine. ![]() When the engine generates heat, coolant is pumped, making your engine cool down. The first cause of engine overheating comes from the coolant. Car engine overheating is mainly due to problems from the above components: Coolant level A well-lubricated motor also reduces friction and helps prevent overheating. The cooling mechanism for a car’s internal combustion engine includes a cooling system and a radiator system. We can say that you should notice all the causes of overheating engine when you experience the phenomenon: a car overheats when ac is off. If you read this far, do you wonder what causes this phenomenon? Let’s move to the next part to find the reasons Why? What Cause The Engine Hot AC Turn Off?Ĭar overheating is the main reason that makes the AC system turn off. Then you can go on driving without any damage.

Let’s find the answer (Photo: ) To lower the load to avoid further heat gain, AC will be off.Ĭurrently, the ECU has a mechanism to control and govern all engine activities by receiving data from sensors in the car, then the signal is transmitted to the ECU for processing, and “output command” forces the actuators to perform such as fuel regulation, ignition angle, automatic throttle…When ECU detects the temperature in your engine is too high, it will automatically control the air conditioner system. You can simply understand this phenomenon that when your engine reaches a high temperature, at this time the engine computer system will be aware that there’s too much heat or the cooling fan is not operating. However, in some cases, our drivers said that they realized that AC turned off when the car overheated. Overheating is one of the most dangerous car engine errors that drivers need to be aware of during operations. If not cooled in time, the car engine will overheat, leading to the risk of fire and explosion, causing danger to drivers. When the engine burns fuel to generate energy, it generates a large amount of excess heat. So you wonder whether you will continue to operate or pull over? In today’s article, we will find the problem: AC off due to high engine temp – What does it mean? And what should we do when you notice this warning on the dartboard?
