Vestel Nova Inverter 122 A++ GI Pro WiFi outdoor unit caught fire; service blamed mainboard and high voltage
Safety risk
Owner of the exact 122 A++ GI Pro WiFi model reports the outdoor unit suddenly caught fire about 8 months after purchase; the authorized service later said the mainboard had burned and high voltage was present, then closed the service record without repair or a written report, while the unit was still under warranty.
What to check. This is a single owner report, not a recall, but it is the exact model and involves flame and a refused warranty repair. Before buying or while owning this unit, keep the outdoor unit clear of combustibles, ensure proper earthing and a surge/breaker setup, and photograph any fault. If an outdoor unit ignites, treat it as a safety event and push for a written service report and replacement rather than accepting a verbal 'not product-related' dismissal.
Vestel Nova Inverter 122 A++ GI Pro WiFi outdoor unit intermittently fails to engage until breaker is cycled
An owner of the exact Nova inverter 122 gı Pro 12000 BTU Wi-Fi model reports the outdoor unit intermittently will not start cooling until the mains breaker is switched off and on; Vestel service attributed it to a voltage fault and said it was not a problem.
What to check. If the outdoor unit will not start and only a breaker cycle restores it, this matches a documented pattern on this model. Have the control board and supply voltage checked under warranty; an intermittent no-start that needs a breaker reset is not normal operation and should be logged with the service.
Vestel Nova Inverter 122 A++ outdoor unit leaks water from day one; indoor unit drips into the room
Multiple owners of the Nova Inverter 122 A++ family report water leaking from the outdoor unit from the first day and the indoor unit dripping water into the room, causing wall stains; the authorized service repeatedly failed to resolve it and in one case charged for a follow-up visit.
What to check. Water leakage/condensation is the most frequently reported issue on this model. Check the condensate drainage and installation (leveling, drain routing) at install time, and get any leak complaint documented in writing while under warranty, since owners report service visits that end without a fix or with a charge.
Nova Inverter 122 A++ GI Pro WiFi error codes ER11/ER13: compressor overcurrent protection
A service-documentation page (sourced from Vestel's own published material) lists error codes for the Nova Inverter 092/122/182/242 A++ GI Pro WiFi family, including ER11 and ER13 as compressor overcurrent protection messages that shut the unit down.
What to check. If the unit shows ER11/ER13, it is a protection shutdown, not a hard failure, and it can be restarted from the remote; but if it recurs frequently, the page advises calling authorized service because an underlying fault may exist. Knowing the code helps you avoid being talked out of a warranty claim.
Vestel 122 A++ GI Pro WiFi manual: R32 refrigerant is mildly flammable
The manufacturer's user manual for the 122 A++ GI Pro WiFi (listed alongside the 092 A++ in the same manual) states the unit contains R32 refrigerant, which is mildly flammable, and warns against installation near flammable gases or in smoky/dusty environments. Note the manual's cover names the series 'Nefes Inverter 122 A++ GI Pro WiFi'; it shares the 122 A++ GI Pro WiFi model designation with the subject Nova unit, so treat this as the same hardware family.
What to check. R32 is mildly flammable, which matters given the reported outdoor-unit ignition event on this model. Keep the outdoor unit away from ignition sources and flammable materials, and have any refrigerant work done by an authorized technician; a leak or a damaged line near a flame source is the risk this warning targets.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
