MCC/Smart Forfour Air conditioning pressure switch replacement
How important is it to replace a faulty MCC/Smart Forfour air conditioning pressure switch?
Air conditioning (A/C) is a basic necessity for many MCC/Smart Forfour 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 MCC/Smart Forfour 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 MCC/Smart Forfour’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.
