Is the oven heating tube bright for a while and not normal?
This is a normal phenomenon, because the electric oven in the work process, automatically control temperature, when the temperature is too high will suspend the heating and air conditioning, maintain the temperature at the set temperature for you, so please don't worry.
When the oven does not reach the set temperature, the heating tube is heated (bright) to the set temperature (temperature), which is the temperature control of the oven.The oven is usually controlled by temperature. It can not be long bright. It also has the function of protecting oven.
The heating tube of the oven is bright (heating) for a while. It doesn't work (stop heating) and is in normal working condition.
