I do not know if this could cause the problem or not but it is hooked up to an extension cord (not sure what size). There are two garage doors plugged in with extension cords. One is working but it is closer to the outlet. Could this be the cause of the problem? Either way I am going to install outlets so she can plug them in correctly.

99% of the time, the issue is the door sensor. Usually an infrared beam, it runs across the bottom of the doorway to reverse the door if anything blocks it. You'll need to check them. There's typically a green light unit (transmitter) and a red light unit (receiver). The red light will flash if there's no beam from the transmitter.
