Garage doors are the largest moving objects in most homes today. As such, these must be well-maintained to ensure the homeowners’ safety and convenience. The garage doors themselves may be made to last, but their parts don’t last as much. Take for example the garage door sensors. Due to ever-changing weather conditions, thousands of operations from the frequent use of garage doors and the passage of time, these devices eventually malfunction.

When the sensors don’t function, your garage door won’t function too. Before you change anything, check if something is blocking the sensors and remove it. You should also check the sensors’ alignment. Garage door openers come with two sensors; one beams a red light while the other beams green. They should always be aligned to face each other.

Think of them as the brains of your garage door openers. They are actually the ones responsible for the safety of your children and pets who non-chalantly cross your garage doors even during operation. When the sensors “sense” their presence, they order your garage door to stop so that your pets or children can pass safely.

This is why replacing your garage door sensors become a necessity once they are damaged or malfunctioning. You don’t have to change the whole opener. There are many sensors available in the market nowadays but you have to make sure that they are compatible with your unit. They must be of the correct size and replacement battery type.
