Arazoak konpontzea
Zerbitzuarekin harremanetan jarri aurretik, berriroview arazo eta irtenbide ohikoenak hauek dira:
| Arazoa | Kausa posiblea | Irtenbidea |
|---|---|---|
| Unitatea ez da pizten. | Argirik ez, urrutiko agintearen pilak agortuta, etengailu magnetotermikoa jauzi egin du. | Egiaztatu elikatze-iturria, ordezkatu urrutiko agintearen bateriak, berrezarri etengailua. |
| Hozte/berotze nahikoa ez. | Aire-iragazki zikinak, kanpoko unitatea blokeatuta, modu okerra hautatuta, tenperatura-ezarpena altuegia/baxuegia. | Clean air filters, clear obstructions from outdoor unit, select correct mode, adjust temperature. |
| Ezohiko zarata. | Pieza solteak, haizagailuaren oztopoa, hozgarriaren fluxuaren zarata (normala). | Check for loose parts. If noise persists or is abnormal, contact a technician. |
| Barneko unitatetik ur-ihesak. | Hustubide-hodia itxita, instalazio desegokia. | Check and clear drain line. If issue persists, contact an HVAC contractor. |
