How To Adjust The Protector System In My Liftmaster Garage Door

Now that we have an idea of what the Protector System is and how it works, we can adjust it to get rid of the problem. Before we can adjust the sensors, we need to locate both the sensors on your LiftMaster.

One of the sensors sends an invisible light, and the other one receives it. If the light gets interrupted, the receiver will interpret it that there is someone or something in the path of the garage doors.

If the receiver and the transmitter are not in the correct position, the receiver will not get the light coming from the transmitter. The receiver will interpret this as a person or object in the path of the garage door, and it will prevent the garage door from closing.

What Is The Protector System Of Liftmaster Garage Door

Lets take a brief step back and talk about the Protector System first before we proceed since it is one of the possible causes of the problem.

The Consumer Product Safety Commission has a regulation in place that requires all residential garage door operators to include a feature that serves as an entrapment-sensing device.

What this means is that any garage door operator, like the one made by LiftMaster, should have a sensor that detects the presence of people or objects that might be trapped under the garage door as it closes. This is the key safety feature for automatic garage doors.

Some sensors will even reverse their movement once it detects the presence of a person under the garage door.

The Protector System of LiftMaster is based on this regulation. It is the system that LiftMaster uses to safeguard anyone that might be under the garage door. The sensor will check for the presence of a person or object under the garage door before it closes as prescribed by the regulation.

Check The Lock Button

In addition to obstructions, youll also want to check the lock button. Most garage door openers have a lock button or a switch that will cause the garage door to stop and sometimes close. If youre not sure where the controls for this are or how to turn the lock feature on and off, youll want to consult the owners manual.

Your Garage Door Remote Control Could Be The Problem

If, while using the operating remote, your garage door refuses to open or close, the remote could be the issue. There are a few reasons why your remote is not working.

• You may be using the remote from too far of a distance away.
• The signal from the remote could be blocked.
• The antenna connected to your garage door system might be damaged. Inspect your system and make sure that the antenna is not only visible but is also hanging down properly from the motor.
• Check the batteries in the remote.
• Lastly, if the remote is not working properly, it may need to be reprogrammed. Read the owners manual to make sure you do it right. Some garage door openers also allow the owner to use an app on their phone to open and close the garage door. Check to make sure youre not experiencing any problems with this app.

The Operator Receives No Power

Sometimes, a garage door wont open or close for one reason only the garage door operator has no power connection. In the funniest of scenarios, the problem will simply be due to an unplugged power cord. You might have absentmindedly unplugged the operator as you were exiting the garage through your internal door to the house. People sometimes do such things and forget having done so.

Often, a more serious issue will prevent an operator from receiving power, such as a blown fuse or circuit breaker. Problems with the circuit breaker should only be handled by a professional.

To summarize, if youre having trouble with your garage operator, its probably either unplugged or it may have blown a fuse. You can plug the cord back in or have a professional service reset your fuses.

The issue could even be due to a faulty outlet. If you plug an electric tool or lamp into the socket, and that also fails to power, the outlet is likely the culprit in which case the operator just needs to be plugged in elsewhere until the faulty outlet is repaired.

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.
