1.What to do if the sash locks don't work properly?
If the sash locks on a double-hung window don't lock properly, check the alignment of the locks. Close the window completely, push the upper sash (or sashes) up to make sure it is fully raised into the frame, then press down on the lower sash (or sashes) to make sure it is fully lowered into the frame. Pressing on the sashes will ensure that the locks are properly aligned so that they can engage with each other.
2.What to do if the sash window doesn't open or close properly?
If you have difficulty raising and lowering a PVC sash window, make sure the pins at the bottom of the sash are properly seated or engaged with the balance shoe. Difficulty in operation may also occur if the sash balance does not properly hook into the hole at the tip of the sash track. This can be fixed by following these steps: First pull the lower sash toward you until it is perpendicular to the sash, then lift one side until the sash's locking pivot arm releases from the sash balance, and repeat on the other side. Lift the sash out of the window frame and place it in a safe place. Next, using a flat-head screwdriver, turn the balance shoe a quarter turn to lock the balance in place. Then, using straight or curved needle-nose pliers, pull up on the hook until it lines up with the hole at the top of the sash track, and insert the hook into the hole. Reinsert the lower sash into the sash and check for proper operation.
