Shut the attic door once you and your partner are in the attic.
Attic door stuck open.
The door latch is not extended before rotating the knob.
Insert a long sturdy item with a flat tip preferably a flat head screwdriver if available between the top rung of the door s top hinge and the head of the bolt securing the door to the hinge.
The knob will not turn to retract the stuck door latch.
If neith of those work can you get the nozzle from a wd40 can through to the latch.
More force is needed to turn the knob and unstick the latch.
The handle or knob must be jiggled to unstick the latch.
Once the door is open try to actuate the door latch with the handle.
Take the door off the hinges.
But if no joy i d just cut or break through and replace the lot.
We have a pull down attic wood ladder with heavy duty springs on each side.
If the door does not allow the lock to be jimmied open it may be necessary to remove the door from its hinges.
In order to get the door to close we have to bend the arm back in as much as we can and hook the spring back over the bracket at the top.
If the hindges are on the outside try taking them off then yank the door open or get a long knife anf try pushing it into the cracks between the door and frame and maybe it will cut through the.
Otherwise try prising the hatch open with say a large flat bladed screwdriver in the gap if it damages the wood slightly you won t see it.
If they are loose tighten them up as much as possible using either a wrench or screwdriver depending on your attic ladder model s attachment type.
