Liftmaster door openers are only available through professional installers. You would ask them to verify the specs (such as rail size, belt size, stuff like that). Call someone in your area to ask what they have in store for you.

I have a wall-mounted controller to open and close my garage door. When I push the close button on the controller, I have to hold it down until the garage door is completely closed. What can I adjust or fix to make the garage door close with just a push of the button?

On my shower door, there are slots that would appear to let water inside the door at the bottom. Won't caulking the door at the very bottom keep that water from escaping, causing mold and mildew?

Yes, that's why you would caulk your weep-holes, not the door itself.

I replaced the broken belt. I have the belt around the drum, on the right side of the idler arm, and the left side of the motor. However, the dryer still will not stay on when I turn the start button. What should I do?

Try switching the belt on the idler pulley and the motor pulley. You actually have it set up in the opposite order for most dryer models; the belt should be...

Do garage door sensors have different colored lights on them?

Yes, they do. Green means that there is nothing blocking the path. Amber or red means that there is something blocking the path and someone tried to close the door.
