When operating, the compressor
vibrates and the motor emits
an irregular buzzing sound.
If it stops, it does not restart
although the sound of the motor
is present.
Single-phase motors:
faulty capacitor.
Have the capacitor replaced.
3-phase motors:
One of the phases of the
3-phase power supply is missing
due probably to blowing of a
fuse.
Check the fuses inside the
electric panel or the electric box
and if necessary replace those
that have been damaged (
fig.

).
Irregular presence of oil in the
network.
Too much oil inside the unit.
Check oil level.

Leaking of condensate from the
vent cock.

Any other type of operation must be carried out by authorized Service Centers, requesting original parts.
Tampering with the machine may impair its safety and in any case make the warranty null and void.
