Frequently Asked Questions (FAQs)
1. What does a high pressure AC switch do?
A high-pressure AC switch is a safety device located on the high-pressure side of the car's A/C loop. It monitors the pressure level of the A/C system and enables or disables the compressor based on two pressure thresholds. Its main function is to ensure the safe operation of the A/C system.
2. Will AC work without a pressure switch?
No, the AC compressor relies on the pressure switch to control its on/off function. If the pressure switch fails, the compressor will not function at all. The compressor is responsible for pumping refrigerant throughout the system, so without it, the AC system will be unable to produce cold air.
3. Can you run AC without a high-pressure switch?
In some cases, it is possible to run the AC without a high-pressure switch if the system is in good condition. However, it's important to note that the switch also serves to protect the system in case of low refrigerant. So it is recommended to have a properly functioning high-pressure switch for the safe operation of the AC system.
4. Can you reset a high-pressure switch?
To reset a high-pressure switch, locate the switch near the compressor. It is a cylindrical device with two wires and a red button on top. Simply push in the button to reset the switch. After resetting, restart the AC unit by using the rocker switch.
