Check the safety reversal.
The safety reversal feature, which is part of your garage door opener, ensures that if your garage door touches anything as it is closing, it will instantly return to the open position to prevent any harm or damage.
Make it a point to check the safety reversal of your garage door because it can protect your family and belongings from the force of the door as it closes. You can test the safety reversal by laying a 2x4 on the ground, and once the door makes contact with the wood as it’s coming down, it should reverse back to the open position.
