What is the reason why the electric oven suddenly can't open the door after baking?

First, the furnace door is deformed. First of all, we should consider whether we will accidentally touch the door of the electric oven during normal use. After the oven door is hit, the screws on the door will fall off, or the hinges on the door will be deformed, resulting in the oven door not being opened. Second, the safety lock on the door is not closed. Generally, a good electric oven will have a safety lock, that is, a child lock, to prevent the electric oven from being opened at work. It may be that there is something wrong with the oven system, which leads to the electric oven never being unlocked after baking, so the oven door cannot be opened. You can try restarting the electric oven. Third, the negative pressure inside the electric oven is too large. When we bake something, we don't take it out in time, and the food inside is easy to expand when heated. When the temperature drops slowly, the air pressure inside the electric oven is different from that outside, and the negative pressure is too large, which causes the door of the electric oven to be firmly sucked and can be opened with a little force. Electric ovens have a wide range of functions, but they also have faults. When you find a problem, you must be calm and find the "root cause" to cure it. The internal temperature of the electric oven is very high when it is working, including when it is just baked, so you must pay attention to safety when using it to avoid burns.
