My garage door won't open? What can I do?

I check the opener parts and all of them are ok.
I even loosen the chain sprocket and ooened the door manually all the way up through the rail. Then activated the ooener and it worked closing the door perfecrly. When I acti aged the opener again the door did not open. The chain seems try to close it again instead opening it. Rhanks for any help. It is a craftsmaster

If your garage door is not opening, there are a few common troubleshooting steps you can take to try to resolve the issue:
First, check the power supply to the garage door opener. Make sure the outlet has power and the opener itself is plugged in and receiving electricity. You can also try resetting the opener by disconnecting the power for a minute, then reconnecting it.
Next, inspect the garage door opener's safety sensors. These sensors are located near the bottom of the door frame and create an invisible beam. If the beam is obstructed or the sensors are misaligned, the opener will not allow the door to close. Clean the sensor lenses and ensure they are properly aligned.
If the door still won't open, manually release the door from the opener's carriage by pulling the emergency release cord. This will allow you to lift the door open by hand. Check if the door springs are still providing the necessary lifting force, or if there are any obvious obstructions preventing the door from moving freely.
Finally, if the door still doesn't budge, the issue may be with the garage door opener mechanism itself. This could be a problem with the motor, gears, or other internal components. In this case, it's best to call a professional garage door repair technician who can properly diagnose and fix the root cause of the problem.
Trying these basic troubleshooting steps can often resolve common garage door malfunctions. But if the door remains stuck, it's important to avoid forcing it and instead seek professional assistance to avoid further damage.
