Before you try to open a jammed door, you need to try to understand the causes of this problem. Most often, wooden doors jam, because of the high humidity and temperature, the wood swells and grows in size. However, the owners of metal doors are also not safe from an accident - jammed debris, deformation of the metal, settling of the building and much more can cause jamming.
If the matter is the swelling of the wooden parts of the door or box - help her dry. To do this, you can use a fan heater or hot air from a hairdryer. When using this method, pay attention - glass elements may burst due to high temperature, and metal elements will heat up to a burning state. In addition, there should be no flammable objects nearby.
Determine which side you need to push to reduce jamming. Most often, lifting and tilting to the side of the loops is effective. When the door can still be opened, do not forget to reduce the load on it, adjust the hinges or slightly correct the problem areas with the help of a planer.
If the door is very skewed, it is best to use a wedge (it can be any strong and sharp object, for example, a screwdriver or a chisel). Drive it as close as possible to the skew point, in the place where the door touches the jamb, and try to straighten the door leaf.
Often the cause of jamming of the door is a small litter or debris clogged in the slot, as well as dried paint. In this case, cleaning with a sharp knife or a hard brush will help.
Another option - jammed door lock. In this case, machine oil, WD-40 (the so-called wedshka) or kerosene will help you. Lubricate the lock with a grease nipple or syringe. Very convenient formulations for lubrication in the form of a spray.
