Fault code 12 — PFC overload current detection of failure

Was bedeutet 12 ?

The Power Factor Correction (PFC) circuit is detecting an overload current. This suggests a system overload, a faulty control board, or a problem with the PFC itself.

• System overloads, and the current is too high
• Control board fails
• PFC fails

1. 1

   Check the system for any signs of overload.

2. 2

   If no overload is found, the control board may be faulty.

3. 3

   The PFC component itself might also be the cause.
