Question about Home Security
When the garage door closes, it goes all the way closed, then the light blinks and it reopens. I can only keep it closed by pushing and holding the garage door button from in the garage

You can adjust the downward sensitivity by turning an adjustment on the opener

Assuming that you do not have anything interfering with the obstruction sensor located at the bottom/sides of the door opening, you most likely will need to adjust the "force-down" control. This control switch should be located on the power-head of your opener. An arrow should indicate direction to turn to increase the force down. You must be careful not to increase it too much or you will create a crushing danger for pets and children. Turn only a little at a time until a test keeps the door closed. You must then place an obstruction under the door (1 inch tall) to make sure it still reverses when an obstruction is met. Sometime temperature conditions will affect the correct operation of the opener and it will need readjustment.

I recommend this to everyone with garage door opener problems:
Use the pull cord and disconnect the opener from the door. Operate the opener and let the carrier slide back away from the door. Is the carrier moving smoothly when disconnected? Next, lift the door by hand from the bottom to the top. Is it moving smoothly? If not, lubricate the hubs of all the rollers on both sides of the door. Check the cable pulleys at the top sides of the door channel, lubricate them as well. Are all cables in all the pulleys, there are 4.
