Description

Air conditioning pressure switch - Mercedes R107 W126 C126 W201 W124 C124 A124 S124 W116 R129 W202 W461 W463 W638

Pressure switch for the air conditioning system of various Mercedes models. This switch is mounted on the air conditioning filter dryer and monitors the refrigerant pressure.

The pressure switch activates when the pressure is too low, thereby preventing the air conditioning compressor from continuing to operate under adverse conditions. This helps prevent damage to the compressor and the air conditioning system.

A defective pressure switch can cause the air conditioning compressor not to switch on or the air conditioning to malfunction.

Additional information

1. Before replacement, check whether the fault is actually caused by the pressure switch. Low refrigerant pressure can also be caused by leakage or insufficient filling of the air conditioning system.
2. Check the electrical plug and wiring for corrosion, damage, and poor contacts.
3. Check whether the thread and electrical connection match the existing pressure switch.
4. Ensure proper sealing during assembly and prevent damage to the threads.
5. Work on the refrigerant circuit may only be carried out by persons who are authorized and qualified to do so. Do not allow refrigerant to escape uncontrollably.
6. After installation, check the operation of the air conditioning and the connection for any leaks.
7. The official Mercedes workshop manual and factory specifications always prevail.

Always check before purchase and installation whether the part is suitable and equivalent based on photos, description, and specifications; installed or used parts cannot be returned.
