If the opener is the heart of your garage door, then the opener’s circuit board is its brain. When you use your garage door remote, the logic board is what relates the signal from the remote to the opener and “kick-starts” the opening or closing process.

However, like every other part of your garage door, the circuit board can fail in a number of ways and cause your garage door opener to stop working correctly. When this happens, your San Diego garage door opener repair technicians will have to either repair or replace the logic board to restore functionality to your door.

But how can you tell if it’s a faulty circuit board that’s causing your garage door opener to behave erratically? Take a look at the 7 telltale signs of a problematic garage door logic board.

How do you diagnose a garage door opener problem?

A malfunctioning garage door opener is more than an inconvenience: it can actually pose a serious safety risk for you and your family. Furthermore, using a garage door with a faulty opener can seriously shorten the life of other components.

Here are some of the causes of opener malfunctions:

If your opener is vibrating or resonating during operation, the motor may have become loose or damaged. If it’s resonating strongly, you should have it repaired ASAP to prevent the opener from falling to the floor.
A damaged safety “eye” sometimes makes a garage door suddenly reverse while opening. This problem is especially common in older garage door models.
Corrosion can cause the opener motor to break down by damaging the limit switches inside the opener. If you notice signs of moisture or oxidation near the opener, you may be dealing with corroded switches.

How do I know if my garage door circuit board is bad?

A faulty circuit board can produce all sorts of strange and unpredictable problems. Because of this, logic board malfunctions can be extremely difficult to diagnose if you don’t know exactly what to look for. When in doubt, it’s always best to have your door inspected by a certified technician.

Here are the top 7 signs of a damaged garage door circuit board:

The warning light is flashing or shining constantly.
Your photo eyes aren’t getting power despite being plugged in. You can check if they’re working by putting something in front of them to see if they detect it.
Your keypad or remote aren’t working as intended. If replacing their batteries doesn’t fix the problem, consider checking the logic board.
Your opener is operating in an unexpected manner. For instance, your remote may cause the door to open only halfway, or open a different door than before.
The garage door opener appears to have no power despite being plugged in. Check the cables and the outlets first to make sure they aren’t faulty.
The LEDs on your photo-eye sensors aren’t blinking or even lit.
Your door is opening on its own.
