To start repairing your Stanley garage door, make sure that your opener is plugged into a live 120-volt outlet. If your remote control is not working, check the battery in the transmitter, and try replacing it. If this does not work, move or coil the antenna wire on the opener.
Occasionally, Stanley garage door openers can be overworked. This causes the overload protector to activate. Wait 10 minutes or so before you try opening the garage door.
Another common problem is a malfunctioning wall button. Inspect the wires to make sure they are not broken or shorted. Disconnect the wires from the back of the opener, and "short" across the two screw terminals. If this process opens the garage door, the wall button wires are broken or shorted.
