Confirm The Photo Eyes Are Clean And Facing The Right Direction
On either side of modern garage doors, youll find two photo eyes. They transmit an invisible beam that, when broken, interrupts the movement of your garage door. The problem could be that they have become misaligned, blocked by a foreign object, or just dirty. In any case, the invisible beam could unintentionally be broken.

Eye Is Out Of Alignment
The photo eye is the safety sensor on the garage door. Its job is to detect a person or object in the way of the door. If you hear a clicking noise and see a light flash from the garage door opener, there may be an issue with the photo eye.
Since photo eyes are sensitive, there are several reasons why the photo eye could be out of alignment. Try these remedies for realigning photo eyes:
Check Your Garage Door Remotes Batteries

If the garage door opener isnt the issue and your garage still wont open, you may want to check the remote batteries. While they typically do last a good while, they will eventually run out of juice and need to be replaced. When the batteries to your garage door opener remote die, it makes it almost impossible to open the garage door from the comfort of your vehicle.
Thankfully, it is a fairly easy fix to replace the battery. Simply follow the instructions for the remote and make sure you buy the right replacement. If you are unsure of how to go about the change, you can bring it into your nearest battery store and they can help you install one.

Make Sure The Photo Eyes Are Not Blocked
- Move larger obstructions out of the way: There are two lenses. One of the lenses acts as a transmitter. It sends a beam to the other lens, which acts as a receiver. This second receiver reads the beam, but if something is in the way, the garage door wont be able to respond.
- Inspect the LED lights on both sides of the sensor: Check to see if one of the LED lights happens to either be flickering or is completely off. If you notice either of these things, the photo eye lens is more than likely faulty. Try and manually re-position the lens to see if it comes back on.
- See if the lenses need to be realigned: Over time, the photo eye lenses on your garage door opener can get bumped into, causing them to become misaligned. What youll want to do is equip yourself with a level. Now measure them and ensure that both of the lenses are positioned at the same height.
- Inspect the wiring connecting the sensors: Look and make sure the cord that connects the sensor isnt disconnected or damaged. Bad weather, water damage, rips, pesky animals, and overuse can cause these wires to become faulty.
Tension Springs Or Cables Are Broken
Your tension springs and cables help your garage door safely reach the ground. If your springs or cables are broken, your door wont close. If your door does close, it will crash on the ground.
This issue is extremely dangerous. If you suspect the problem is in your springs or cables, call a garage door repair service immediately.

Transmitter Or Garage Door Opener Issues
Do you notice the issue occurs when you use your garage door opener? Try closing the garage door with your opener remote first. Then, try closing the garage door with the button inside the garage.
If the garage door closes with the button but not the opener, then your opener, or your transmitter, isnt working.
Common transmitter issues include being too far away and your neighbors transmitters interfering. You may also need transmitter repair or a new garage door opener. Its best to consult with an expert first.
The Transmitter Batteries Are Dead
This may sound obvious, but your garage door transmitters need power to work. If the batteries in your transmitter are dead, the transmitter wont be able to send a signal to your garage door to open.
First, check to see if the transmitter on the wall inside your garage still opens your garage door when pressed. If it does, then the transmitter in your car likely just needs a simple battery replacement. If you have more than one car transmitter for your garage door, then your other transmitters will likely need new batteries soon as well, since they were probably installed around the same time.
Changing the battery on your garage door transmitter is pretty simple. On most, you can simply slide the door open on the back of the transmitter and remove the battery. Others may be screwed in to keep the battery more secure, so this type of transmitter will require a screwdriver to open.
After removing the old batteries, make sure the plus and minus signs line up with the plus and minus signs on the inside of the transmitter. Otherwise, the new battery wont work in the transmitter, and it could give you a false sign that something else may be wrong. Once the battery is in place, test the transmitter, and if it works, replace the transmitter door.

The Garage Door Is Locked
If your garage door has a locking mechanism, verify that it isnt engaged.
Some garage door openers have a lock mode that is activated when you hold down the open/close button on the keypad for several seconds. When the lock mode is engaged, simply pressing on the button wont do anything you need to hold down the button again in order to unlock the door.
Other types of garage doors have manual locks that are opened and closed with handles placed on the outside of the garage door. These doors may become locked if someone unintentionally pushes on the handle. Simply turn the handle to unlock the door when this happens.
How To Reconnect An Opener Without An Automatic Trolley:
If you tried connecting the garage door automatically and it did not work, you might not have an automatic trolley on your garage door opener. In this case, youll have to connect the arm of your garage door to the trolley manually. You can also use this method to reconnect the garage door to the opener before the power returns.

What do you do when your garage door wont open? You call a professional technician to inspect and repair your roof.

Before calling a professional, try these easy fixes:

The Door Track Is Misaligned
When it comes to the workings of a garage door system, the operating mechanisms activate the door, and the cables lift and lower it physically while the springs manage the tension. However, none of these actions could possibly remain centered along the garage doorway and ceiling if not for the metal tracks that keep the door in line. Therefore, the tracks that guide the door must be straight and even on both sides.
If either track becomes slightly ajar, it can slow the movement of the door. As time goes on, the problem is liable to get worse. For instance, a bend at any point along one side is bound to pull on the door, which, in turn, will put pressure on the other side and effectively duplicate the problem on the mirroring track.
Pressure and natural wear and tear can cause misaligned door tracks. Always call a service to get these tracks replaced and get your garage door working again.
If one or both tracks is bent, you might hear a squeaking sound as the rollers pass the affected area. The movement of the door might slow just slightly as it passes this spot. A problem like this can grow out of hand as the months wear on, and the weight of the door causes further stress. If you know or even sense that your door tracks have lost their alignment, call a service specialist immediately.

Can I Use A Patio Heater In My Garage

Patio heaters are designed to be used outdoors. The propane gas is flammable and it is never a good idea to use it indoors. If you use the patio heater in the garage with the doors closed, the emissions of these gases can be fatal. Patio heaters are regulated for outdoor use only so they should never be used inside.

Your Photo Eye Is Out Of Alignment
You may remember a time as a kid when you and your siblings would close the garage door and run underneath it as fast as possible to make it out before the door closed. Well, on any garage door installed after 1993, thats no longer possible thanks to two tiny photo eyes on either side of the garage entrance. These photo eyes transmit an invisible beam between each other that detects if anything is in the garage doors path when it closes. This safety measure is there to prevent automatic garage doors from closing on top of someone or something and causing serious injury or damage to property.
If you notice that the garage door opens normally but doesnt make any attempt to close when the remote is pressed, the first thing youll want to do is visually inspect the photo eyes. Over time, these eyes can get dirty, causing the light from the beam to be blocked. They also can eventually become misaligned, causing the eyes to not match up on both sides.
When cleaning the photo eye, you should take care not to scratch or damage the eye since its made of glass, similar to that of a camera lens. The photo eye itself is pretty small, only a few centimeters in diameter, but it can get dirty rather easily. To clean it, youll need a soft cloth and a mild, streak-free cleaner. Gently wipe away any dirt or residue that has built up on the eye and be careful not to oversaturate as excessive wetness can cause dirt to stick to the eye more quickly.
