Frequently Asked Questions

Why does my garage door open by itself during storms?

Static electricity generated during storms can sometimes trigger the sensitive electronics in garage door openers. To mitigate this, consider installing a surge protector to shield your garage door opener from electrical surges.

Can a weak battery in a remote cause my garage door to open by itself?

Yes, a dying battery in your remote can send incomplete signals, which might be interpreted as an open command by the garage door opener. Replacing the battery is a simple and effective solution.

Is it possible for a power surge to cause my garage door to open on its own?

Power surges can indeed affect garage door openers. These surges can reset the system or damage the circuit board, leading to unpredictable behavior. As mentioned earlier, using a surge protector can help prevent this issue.

How can I ensure my garage door doesn’t open by itself?

Regular maintenance and checks are key. Ensure that your garage door opener’s frequency is unique, the wiring is intact, the sensors are clean and aligned, and the remote control is in good condition. Additionally, consider upgrading to a newer garage door opener with enhanced security features.
