Samsung NV75N5671RS Dual Cook exterior glass shattered spontaneously after 3 years (no impact)
Verified owner review on Samsung's official French product page for the NV75N5671RS. The reviewer (Portuguese) reports the exterior glass shattered spontaneously after ~3 years of normal use, with no impact, no prior crack, and no damage. The reviewer concludes it was poor manufacturing and notes it happened right after warranty expired. This is an independent confirmation of the glass shattering failure documented on the Darty forum.
What to check. This is a second independent confirmation of spontaneous exterior glass shattering on this exact model. The failure occurred after warranty expiry (~3 years), meaning the owner bears the full replacement cost. Consider whether this risk is acceptable.
Owner on Darty SAV forum reports the lower exterior glass of the Samsung Dual Cook oven exploded spontaneously. A second respondent in the same thread reports the oven self-starting repeatedly and paying €281 per repair. The glass shattering is a documented failure mode for this exact model (NV75N5671RS).
What to check. If you own this oven, inspect the exterior glass for stress cracks. If it shatters, contact Samsung support and the retailer. Do not use the oven if the glass is compromised. Replacement glass is a significant cost.
Samsung NV75N5671RS Dual Cook oven self-starts and heats unattended — fire risk
Safety risk
Multiple owners on the official Samsung Community forum (EU) report the NV75N5671RS turning itself on and heating at any time of day or night without user action. One owner reports paying over €600 for repairs after 2 years of use. Another states the oven 'endangers our homes and our lives'. The thread has 84 replies, indicating a widespread issue.
What to check. This is a serious fire risk. If your oven self-starts, unplug it or cut power at the circuit breaker immediately. Do not leave it plugged in unattended. Samsung's after-sales service may charge for the repair even though the fault is a known safety issue.
Samsung NV75N5671RS Dual Cook self-starts and heats to 170°C just 3 months after warranty expiry
Certified owner on Darty SAV forum reports the NV75N5671RS turning itself on and heating to 170°C, just 3 months after warranty expiry. The owner notes many similar cases on Samsung's own website. This is a third independent report of the self-starting fault on this exact model.
What to check. The self-starting fault appears to occur around or just after warranty expiry, meaning owners bear the full repair cost. If your oven self-starts, unplug it immediately. Document the behaviour with video evidence before contacting Samsung.
