Why Is My Delonghi PAC EX100 Silent Displaying Error F2?

Possible Causes of Error F2

If your Delonghi PAC EX100 Silent is displaying an F2 error, one of the following could be the reason..

Bad temp sensor

One of the very notorious causes of the F2 error code is a defective temperature sensor.

You see, since this sensor detects the temperature inside your unit, it can trigger the F2 error when it stops working

Clogged air filter

Another pretty common cause of the F2 error is a clogged air filter.

Thing is, when the air filter becomes dirty and blocked, it restricts the airflow.

That in turn tends to cause the AC to overheat, and the F2 error.

A wonky control board

If not the above two, it could be that you either have a bad control board in there or there’s an issue with the compressor….both situations occasionally result in the F2 fault code.

In fact, F2 error points to a fault with the Invertor module….
