I wanted our old combi boiler (hot air, microwave, barbecue) from Samsung that operation had become somewhat decrepit after 12 years, send retire. Since the selection of well-reviewed, tested and evaluated device is low, the choice fell on this. The unit was functional and comparable by the operator with the old device, and was to these attributes and is exposing nothing. Until it turned out that the Sunday rolls instead of 10 now needed 20 minutes. So I grabbed the Backofenthemometer, brought the old device again from the basement and started a series of measurements. Result: No matter what temperature I set the old device reaches the target temperature + - 10 degrees in a short time, the new device never. The heating curve looks something like this: 200 degree set, slowly heated to 100Grad, inserted break, further heated to 140 degrees, changed in the set-point control (you can hear nice switch the relay in and out), and from then on, the temperature rises in the next many minutes on max. 155Grad on. After 25 minutes, I have the trial canceled. Both units equal to the heating coil on the back wall in front of the fan. I would have expected that the spiral is energized and hinglüht to reach the desired temperature in shallow red before him. This is done in the old device, but not the new one. At first I thought to have caught a Monday device. But the second device showed the same behavior. If you have read through other 1-star reviews on this device, you can see that there are other customers have observed the same symptoms. I assume that the temperature control, or parts of these (sensors, driver), simply do not work and it is thus to be a systematic problem. Maybe I also just caught a failed batch. Tip: Just 3 invest, buy an oven thermometer and measure. The cheap devices are not calibrated for deviations greater than 20%, but you can start from a problem.
Notes: - To test the microwave power to me an appropriate meter absent. However, I can say that in direct comparison with the old device, the new device has the same amount of water heated noticeably slower. - I have the Samsung combined unit not ordered from Amazon but in another large electrical appliances shipping. The product obtained after the returning second device was a new unit. Any attempt at repair has not occurred. - I now have the power of Severin (MW 7848) are at home, reaching the desired temperature in the shortest possible time. Not quite as fancy, but effective and it does what it should.
