A door closer hold open works by using a mechanism that allows the door to be held in an open position at a specific angle. This mechanism typically includes a friction hold open arm or a mechanical hold open device that can be engaged to keep the door open until it is manually released.

On a LCN door closer is there a way to control the resistance upon opening the door on a parallel mount?
If you are trying to control the amount of resistance or force required to open the door, there are two adjustments that can possibly be made. The first thing to check is the back check valve. This valve adjustment is used to cushion the door from opening too far. If this valve is adjusted improperly, the door will start to slow down too soon in the opening cycle and will be hard to open. The other adjustment is the power adjustment. This adjustment sets the spring adjustment and sizes the door closer. Adjusting the sizing spring will make the door easier to open. If you can provide me with a model number I can provide you with a link to the manufacturer's instructions for installation and adjustments. if the closer is a LCN 4040, they have a valve on the back (surface that touches the door when its mounted) that is the backcheck selection valve, it is really important when installing the door closer on a paralell mount to CLOSE the valve (turn Allen wrench to right as far in as possible until it stops) if this step was missed during installation of the LCN 4040, what you can do is open door, close both sweep and latch valves on the closer then remove the 4 mounting screws, pull closer from the door a little so you have room to get Allen wrench behind closer to close the valve, when its closed, put closer back on door and put the 4 screws back in and adjust the sweep and latch valves back to were they were, if the closer is a 4010, you will see the valves at top of closer body, these 4010's DO NOT have the backcheck selection valve. if you DO NOT close the valve when installing the closer to push side of the door, backcheck will not work because of the geometrics of the arm angles the closer's internal piston does not reach the backcheck adjustment valve and dampen opening force. if you are going to install the 4040 on push side using parallel arm, close the valve, if mounting the closer on the PULL side of door with regular arm mounting OPEN the valve (about 3 or 4 complete turns) hope this helps
How to open a Volvo door that will not open?
If the door won't open from the outside when you press the handle, you need to take apart the interior part of the door and the mechanism. There is a barrel that slides in a groove that has jumped out causing the door to not open from the outside. If you have auto locks they will not work either. Only opening the door from the inside will work since that pushed the lock from another position. Hope that helps.
How does a spring hinge door closer work to automatically close a door?
A spring hinge door closer uses a spring mechanism to automatically close a door. When the door is opened, the spring is compressed. Once the door is released, the spring expands, pulling the door closed. This helps to ensure that the door closes securely and automatically after it has been opened.

When you open a door what force do you exert on it is there any work done?
When you open a door, you exert a force in the direction of the door's motion. This force creates torque, which causes the door to rotate around its hinges. Work is done when this force causes the door to move against resistance, such as friction between the door and the door frame.
