It’s a strange occurrence when the garage door suddenly opens by itself.
It can either be surprising or frightening.
For some who had this experience, as odd as it might be, there’s typically a clear explanation.
If this is happening to you, you should address it.
Mainly since a garage door that opens on its own can pose a security risk and increase your home’s heating and chilling bills if left open for long periods.
A garage door that opens by itself reduces the garage door in serving its purpose.
So, the garage door specialist by Max Garage Doors shares here the answer to “why does the garage door open by itself?”
Garage Door Styles
Below are the four main types of garage doors in the US:
- The sectional roll-up door is by far the most common alternative. It is used not only by residential houses but also by businesses and shops.
- If the goal is keeping the ceiling clear or want a unique look, swing-out garage doors or sliding barn garage doors remain a good option.
- The swing up or out garage doors are also typical in residential areas.
- The roll-up and side garage doors are popular with business establishments.
Role of a garage door safety sensor
Regardless of the style of the garage door, each has a sensor.
That is because garage door sensors are a vital component of garage doors and a safety function.
Since 1993, most automatic garage doors have been expected to have these components.
Their primary role is to detect potential obstructions when a garage door is closed.
Garage door experts from Max speak from experience on the question: “Why does the garage door open by itself?”
- Worn out or old batteries – often, the most basic likelihoods are the most likely. Long-standing batteries in garage door remotes might be the trigger, as long standing batteries can cause malfunctions, the most common of which is a random door opening. Solution: Try replacing the batteries on your remote.
- Sticky keypads – Dust and debris may trigger buttons on the mounted part of the garage door sensor or the remote to stick over time. When the keypads get stuck, they will remain semi-pressed most of the time, resulting in erratic garage door opening and closing. Solution: Cleaning the buttons with cotton swabs and some water and soap mixture will help restore their functionality.
- Power surge – An unanticipated power heave caused by thunder will every now and then trigger garage door openers to fail. It can result in unexpected opening or closing. Also, if your problem is unusual or appears to be a remote occurrence, this may be the cause. Suppose the lightning storm or power surge did not permanently damage garage door sensors. In that case, there might be no need for maintenance, and the opener may resume on its regular operation.
- Old Transmitters – In the 1990s, garage door manufacturers used similar transmitter frequency in a specific neighborhood. Thus, those who have old garage doors in the same community might be picking up common signals.
- Circuit board problems – The circuit board is the internal computer, or “brains,” of the garage door opener. It controls all of the system’s external operations.
Down Garage Door Sensor
If any of those above isn’t the reason, it may be high time to replace that garage door sensor, lest your safety will always be in jeopardy.
Here is how to know if that garage door sensor has gone wrong.
- If your sensors aren’t working correctly, there may be an impediment in the sensor’s signal’s way. If there are any items, remove them before attempting to close the door.
- Sensors are generally equipped with tiny LED lights that should be switched on. If the lights in one or both of the sensors are switched off, they are not powered. Try reconnecting the power supply in this situation.
- Dirty sensors can cease to work correctly. Clean them of dust and dirt, and then test them to see if they perform.
- Moisture around the sensors may be the cause of the malfunction. So, dry them out and test them to see if they still function.
- Physical damage to the sensors can also cause them to fail. Normal wear and tear may also be the source of the issue. Examine the item for harm and then contact a professional for a repair.
Those are the advice from the experts and only the primary and most common issues.
At some times, your case may be unique.
