The electric oven has a crash
The oven works in a different way than the microwave oven, and does not vaporize the heat inside the heated object;
This can occur on display tubes, television sets, etc., even after a period of time. Of course, you can't rule out the noise caused by heating in the heated object, but the roast duck may be burnt locally.
The new oven use "collapse, collapse" sound, may be the original timing is under normal temperature, between components at room temperature or fastening screws, and the first heated to a higher temperature, due to thermal expansion, when the deformation force is larger than the connection strength, produce deformation causes slip occurred in the junction, which leads to the appearance of "collapse, collapse" sound, when the temperature is stable, it will not happen again;
