Garage Door won't open and close

So … the device lost its sticky hold on the garage opener so after reapply the device to the garage opener with some velcro, I thought everything would go back to working they way it was before. I have reset the device and set it up again but still does not open when I hit open and does not close when I hit close. Help! Very frustrating …

Does is correctly report the status of the door?

Perhaps the wires inserted into the opener came out a little? Did you just stick the unit back on or did you start all over? A small device but enough weight to pull the wires away from the contacts…they may look like they are in there but there could be no contact inside…
