Someone may already have traced it or can help identify function.
Always isolate the mains before measuring resistances or replacing parts.
: Often caused by a blown fuse or a failure in the AC-DC converter module (check the VIPer series or similar PWM ICs).
This section drops the high voltage down to lower, stable levels, typically +18V (for the cooling fan and IGBT driver) and +5V (for the microcontroller).
Let us break down each functional block as depicted in the .
Inspect the 5µF filter capacitor and the 0.3µF resonant capacitor for swelling or loss of capacitance. Sensor Errors (E0, E1, E2) Symptoms: Display shows an error code and beeps.
