Costly or dangerous
Heavy smoke from the rear of the oven during cooking; owner demanded refund on safety grounds
An owner on Şikayetvar (complaint 'Mini Fırında Aşırı Duman Ve Güvenlik Riski, İade Ve Ücret Geri Ödemesi Talebi', 28 March) reports thick smoke pouring from the rear of the oven during cooking, filling the kitchen, and asked for a refund citing both safety and health concerns.
What to check. A reported heavy-smoke event during normal cooking is a fire and inhalation hazard. If you own or buy this oven, run the first use in a ventilated space and watch the rear of the unit; if dense smoke appears, stop use and pursue a refund or exchange rather than accepting a repair.
Oven-door glass cracked while cooking; service charged for the part
An owner on Şikayetvar (complaint 'Mini Fırın Camı Çatladı, Servis Ücreti İsteniyor, Çözüm Yok', 12 July 2025) reports the oven-door glass cracked while cooking, and that Beko's service asked to be paid for the service and part before even visiting.
What to check. If you buy this oven, check the door glass early and document any crack immediately; the owner's report indicates Beko treated the cracked glass as a chargeable repair rather than a warranty failure, so a glass failure could cost you the door assembly out of pocket.
Interior enamel coating flaking/bubbling after about four months of use
An owner (complaint 'Garanti Kapsamındaki Beko Fırın Emaye Çatlaması İçin Ücretsiz Onarım İsteği', 25 March) reports the interior enamel flaking/bubbling in the lower part of the oven after about four months, while still under warranty.
What to check. This is a quality/reliability defect rather than a safety hazard, but it means the interior finish can degrade within months. If you buy this oven, inspect the interior enamel early and file any flaking claim while the warranty is still active, since the owner's report shows it appears within the first year.
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.
