A cupboard door that hangs is usually the hinge screws
I opened the sink cupboard in June and the door dropped a finger's width. It caught the next door and left a tapered gap at the top. I thought the hinge had bent. I took the door off. The two screws in the carcass plate were spinning in dust. The chipboard holes had gone. The hinge was straight. It had nothing to hold.
A cupboard hinge is a pair of flaps and a plate. The plate needs screws that bite. In a kitchen that is usually chipboard. Chipboard holds a screw once. After that you are turning a hole into a crater. The door hangs, rubs, and then the next door starts to go because you keep slamming this one. People order new doors. I move the plate, or I fill the holes and put screws into something that still exists.
A kitchen drawer that sticks is usually the runner is the same unit, different hardware. A walking screw is a walking screw. I do the drawer slides and the door plates the same way. I do not buy a kitchen because one door dropped.
When I check I open the door and I lift it. If the gap closes when I lift, the screws are loose or gone. I look at the plate on the carcass, not only the cup in the door. The cup can be tight and the plate can still be walking. I try the screws. A screw that will not snug is a blown hole. I take the plate off. I put a matchstick or a dowel in the hole with a bit of glue, or I move the plate a few millimetres onto sound board, and I use screws that are thick enough to bite, not the same tired ones. I do not put a longer screw through the back of a thin panel into the pipe space. If I can see daylight, I stop.
Once the plate is tight I hang the door and I use the little cams on the hinge if it has them. A millimetre of height or overlay, not a bend in the arm. If I am bending the hinge, the screws are still the job.
Skip a new kitchen because one door hung. Skip forcing the door until the edge chips. Skip mixing screws from a mixed tin that are too fat and split the cup. Skip oil on a hinge that is off the carcass. Oil will not fill a hole. Skip packing the cupboard so full the door never sits and then blaming the hinge. If the box is coming apart at the cam dowels, that is the box. I stop.
Bathroom cupboards fail the same way, faster, because of steam. The board swells and the holes go sooner. I still start at the screws. I wipe the plate dry. I do not leave a wet cloth on the hinge overnight.
UK year is whenever you cook, and after a wet winter in a bathroom. I now lift a dropping door before I lean on it. If I can see the plate lift with the door, I do the screws that afternoon, not after I have bruised the next door.
I hang it and I look at the gap. Even, and it stays even when I let go. If it drops again, the hole is still dust and I have not moved the plate far enough.
I do not need new doors because this one hung. I need screws that bite, a plate on timber that is still there, and a cam I only turn after that.
If I later add a buy link here, it will be a paid promo.
