When an AC unit is exposed to electrical problems, it can lead to the compressor receiving too much or too little voltage. Liquids are relatively incompressible; while some can be compressed, the main action of a pump is to pressurize and transport liquids. The reason behind is the overheating and drawing too much power, causing the circuit breaker to trip. Siemens cautions that only an approved airline antifreeze should be used no coolant, rubbing alcohol, methyl hydrate, or anything else that could potentially contaminate the air system.

The main function of an AC compressor is to compress the low-pressure refrigerant from the evaporator and then release it as high-pressure vapor into the condenser. One of the most common signs is a loss of air pressure. But if there is a leak, then this not only raises harmful health issues because of the chemical component but also raises energy consumption.

Home Trucks Common Signs Of A Bad Truck Air Compressor. The refrigerant is then compressed, which condenses into a fluid, and is then released under pressure. Our shops perform annual air drier services on all trucks in the fall replacing desiccant cartridges, testing heater elements, servicing purge valves and we also purge the trailer air system, he says. The compressor is housed within the condenser unit and the component that starts the chain reaction cools the refrigerant. The voltage there should be between 10-16 volts, depending on the model of the car you are testing. If your air compressor is overheating, it could be due to a problem with the cooling system.
