This Delonghi Convection Oven, EO1270, made in China under the name “德龙“， came to me in near pristine condition. It looked like it was used only a couple of times. Yet when I plugged it in it would not work. I decided to take it apart and see if I could repair it. It was pretty evident that this oven was not designed to be repaired. In the end I found a flaky on-off switch, which could have been replaced, but to get to the electronics I’d have to drill out a couple of rivets. This repair would not have been worthwhile.
The Delonghi name looks to be from Treviso, Italy, but this oven is manufactured in China:
De’Longhi（德龙）是意大利主要的小家电生厂商之一，始创于1902年的意大利的特雷维索， 20 世纪 50 年代，德龙集团正式成立，主要为其他的公司供应取暖系统的零部件。
20 世纪 70 年代公司公司开始推出自己品牌的产品。现已成为中高档生活电器的设计、研发、生产和销售的跨国集团。其产品涉及多个领域：咖啡机系列、厨房电器系列、加热电器系列、空调/空气净化系列、清洁/熨烫系列，业务遍及全球80多个国
De’Longhi (DeLong) is one of Italy’s leading small household appliance manufacturers. It was founded in 1902 in Treviso, Italy. In the 1950s, Delong Group was formally established to supply heating systems to other companies. Parts.
In the 1970s, the company began to launch its own brand of products. Now it has become a multinational group of design, research and development, production and sales of medium and high-end living appliances. Its products cover a wide range of fields: coffee machine series, kitchen appliances series, heating appliances series, air conditioning / air purification series, cleaning / ironing series, business in more than 80 countries around the world
The back panel came off pretty easily. The electronics were all on the left side, with the rest of the oven an empty space for your cooking. It was then clear that to access the electronics and trouble shoot I’d need to remove the top cover, which included the sides, and near disassemble the whole oven. After removing the side screws I found that the top cover was riveted shut. I would need to remove the door controls, bend the door back and drill out a couple of rivets in order to access the electronics.
Once the door controls were removed and rivets drilled out I was able to remove the top cover and examine the electronics. This convection is was really made cheaply and was not easily repairable. The ground from the power cord was riveted to the chassis bottom panel.
The non-replaceable fuse was sheathed in a short plastic tube and bolted to the frame. This could not be replaced. The fuse tested ok.
I removed the on-off switch, which tested poorly. It would turn on once every 4 tries. This was the bad component. In order to do this simple multimeter test I needed to rip the oven apart, pretty much stripping it down to the carcass.
Further investigation showed that one of the plastic knobs was broken. Though reinforced with a coil of wire, if removed it would have fallen apart.
Summary: This convection oven is a throw away item. If you need to even look at the electronics the work involved requires irreparable damage to the oven. The on-off switch is a specialty item that combines on-off with a variable timer. This cannot be replaced with simpler, more robust parts. I would not recommend this line of appliances to anyone. Buy better quality, as this one will not last much past the year warranty.
