Lexus Air conditioning pressure switch replacement

Does Your Lexus Air Conditioning Pressure Switch Need to Be Replaced?

Air conditioning (A/C) is a basic necessity for many Lexus owners.

When your A/C is not operating at its best, it can be a major inconvenience.

If the A/C is not working at all, well, this could signify a complete catastrophe, especially in an Australian summer.

When an A/C pressure switch fails you might only realise it’s not working when your Lexus doesn’t cool down.

The low-pressure switch needs to detect enough A/C refrigerant pressure to close the circuit and the high-pressure switch will remain closed unless the refrigerant pressure gets too high and then it will open the circuit.

If a switch detects too little or too much pressure the circuit will remain open and no power will proceed to the compressor clutch.

If your Lexus’s compressor was to operate with the wrong refrigerant pressure it will damage the unit so it's best to get the pressure switch replaced as soon as a problem is detected.
