If your cabinet door won't close, and it has this type of hinge, straightening the door is usually just a matter of tightening some screws. When a door is visibly off level and has surface mount or another type of non-adjustable hinge, you may have to level the door by resetting one of the hinges to make it close.
Fix any issues with the hinges – If the hinges seem to be the problem, fix any loose screws or replace worn hinge pins on older hinges first to see if that resolves the issue. If your hinges are painted, you may just need to replace them.
Adjust Door Up or Down
Often, turning the screw a quarter-turn or less counter-clockwise is enough to loosen the screws enough to let you move the door. It's preferable to have the screws too tight than too loose. Gently close the cabinet door. With the door still closed, adjust the cabinet door to the desired height.
To do this, you may need to remove the hinge and reinstall it in proper alignment, or there may be a screw you can adjust to realign the hinge. Once the overlapping doors have been realigned, the door should stop slamming shut unless there's an issue with other settings in the soft close hinges mechanism.
Factors like the changing of the weather and humidity can prevent a door from closing properly or cause it to stick in its frame. Your wooden door may shrink or swell because of changing weather conditions, especially if it's old or unprotected.
If the latch is too high or too low, try tightening your door's hinges. If your door still won't close after that, remove one of the screws on the jamb side of the hinge and drive in a 3-in. screw–it will help pull in the whole doorjamb.
The moisture expands the wood, making your doors too tight in their frames. In the winter, humidity levels are usually lower, because cooler air cannot hold as much moisture. If you have better luck with these doors in the cooler months, it's simply because environmental factors are not causing them to swell.
Cold temperatures will cause your door to expand, which means it may stick and be difficult to close. If it's made of wood, it may soak up water from humidity and eventually become damaged. Door parts, including the frame, hinges, jamb, and hardware, can also be damaged by extreme cold.
Wood is a natural material that can absorb heat or moisture from the air and start expanding. When this happens, it begins to rub on the framework and is difficult to shut and open. It's quite reasonable in the period of heavy rainfall for doors to swell since the climate is wet and humid.
If you have the perfect shim or shims thickness, your problem will be fixed. If the bottom of your door (below where the lock and door handle are located) is hitting or rubbing the bottom of the door frame, then you need to add a cardboard shim to the very bottom and possibly the middle hinge also.
As a door or window is opened and closed, the hinges begin to loosen to the point where they do not hold firmly. These become unbalanced and begin to collide with the frames. The good news is that repairing the hinges is simple, and you only need a screwdriver to tighten the screws.
Place the shims between the hinge leaf and the door at the top and middle hinges. This will shift the lower half of the door downward. Place the shims between the hinge leaf and door at all hinge locations. This will shift the door towards the lock side.
Sanding the sticky areas of the door should do the trick for this issue. Reducing indoor humidity can help in preventing wood doors from swelling. Open your windows, or turn on your exhaust while cooking or showering. In some cases, refinishing the door fixes the problem.
Rubbing soap or wax on the sticking area will often help. Silicone spray lubricant, sold at most home centers and hardware stores, also can be used. Try shims. A thin filler or shim behind one of the hinges will often free a door that sticks near the top or bottom of the latch side.
Improperly aligned hinges can prevent your door from staying shut. A door that does not stay shut is usually improperly aligned at the hinges or at the strike plate and latch. This can be caused by settling of the house, improper installation of the door, or damage caused by slamming or excessive use of the door.
Self-closing cabinet hinges that won't close might be poorly adjusted. The cabinet door might overlap the neighboring door, be crooked or sit too far out from the cabinet face. All of these issues could interfere with the hinge's self-closing ability.
