Why won’t my garage door close?

It is very frustrating when you go to close your garage door and it starts to go down and comes right back up! The most common reason that this happens is because the safety beam sensors located at the bottom of your garage door. These sensors are very sensitive and if there is anything blocking the beam, such as a blade of grass or cob web, will cause the door not to go down. Also if the sensor is not lined up properly it will cause this as well.

How do I fix this problem?

It is actually very simple to fix this problem yourself without having to have one of our service technicians some out and fix it. There are a couple of ways for you to test or troubleshoot this problem. Sometimes it can be the wiring itself or a short in the wiring. You can inspect the wiring yourself with these simple steps:

Check for incorrect wiring between the sensors and the garage door opener.
Verify the wire connections are correct on the garage door opener. The solid white wires connect (insert) to the white terminal and the white and black wires connect to the grey terminal.

Note: The amber LED on the sending sensor will glow regardless of alignment or obstruction. If the green LED on the receiving sensor is off, dim, or flickering (and the invisible light beam path in not obstructed), alignment in required.

How to test the wiring?

There are also simple steps to test the safety sensor wires.

Remove the sensors from the brackets.
Remove the wires from the wire nuts or cut the sensor wires 12” from the sensors.
Strip both ends of wires from each sensor and twist like colored wires together. Proceed with both sensors to the garage door opener motor unit.
Remove existing wires from the white and grey terminals on the back of the operator.
Attach or insert white wires into the white terminal and black/white striped wires into the grey terminal.
Point the sensors at each other-if both sensor LED’s turn on, there is an issue with your wiring. Replace the wires between the opener and the sensors. If the LED’s DO NOT turn on, replace the sensors.

Note: If after replacing the sensors, the LED’s still do not light, it could be the circuit board or even a new opener.

If it is not fixed what do I do?

If after trying these steps and your sensors are still messing up there may be some bigger issues at hand. In that case you might want to give us a call and have a technician come out and give you a free estimate. Do note that if you cannot get your garage door to close because of the sensors, you can hold down the wall console button inside your garage and it should close all the way. That way you can get it closed if you are in a hurry and we can come out right away. Just give us a call at (972) 422-1695 to schedule your free estimate!

How to Identify Common Residential Garage Door Repair Needs

February 23, 2026

Garage doors are among the biggest moving parts in your home. When something goes wrong, it can disrupt your entire day and pose safety hazards. Homeowners searching for residential garage door repair in Dallas, TX , often notice problems during harsh weather changes or after years of everyday use. At Plano Overhead Garage Door, we want to help you spot issues early and keep your garage door working safely and smoothly. Common Signs Your Garage Door Needs Attention Knowing when residential garage door repair is needed can save money and prevent accidents. Some warning signs are easy to spot once you know what to look for. If your door makes loud noises, sticks, or doesn’t open and close easily, repairs are likely needed. Unusual sounds like grinding or squeaking often mean that residential garage door repair is required for parts such as rollers, springs, or hinges. Doors that wobble or move unevenly may be off track. These and similar signs all suggest it’s time for a careful inspection. Broken Springs: A Frequent Problem Springs do the heavy lifting in residential garage door repair. They help your door open and close smoothly. Over time, Texas heat and humidity make springs break down faster. If your garage door feels very heavy or won’t open, a broken spring may be the cause. Trying to fix springs without proper tools can be dangerous. A snapped spring can cause serious injuries. It’s best to contact a pro who understands residential garage door repair and can replace springs safely. Off-Track Doors and Their Dangers Bent or blocked tracks easily lead to doors coming off track. A door that leaves its track won’t move right and could collapse. Hot Dallas summers cause metal tracks to expand, making the problem worse. If you notice your door is crooked or stuck, residential garage door repair is needed. Don’t try to force the door, as this risks further damage and injury. Opener Problems and Sensor Issues Garage door openers make modern life easier but often need repairs. When the remote or wall button stops working, or the motor grinds but the door doesn’t move, you may have an opener problem. Sensors play a crucial safety role in residential garage door repair. Texas storms or high humidity can affect sensor alignment. If the door won’t close or reverses unexpectedly, check for dirty or misaligned sensors. Professional help ensures correct repair and keeps your family safe. The Impact of Texas Weather Dallas weather is tough on garage doors. High heat, fast temperature swings, heavy rain, and storms all speed up wear. Metal parts rust faster, springs lose tension, and wooden doors swell or crack. These conditions increase the need for residential garage door repair and regular inspection. As the weather changes, inspect your garage door for signs of damage or excess noise. Routine checks and early maintenance help avoid bigger repairs. DIY Risks: Why Professional Help Matters Watching online videos might make residential garage door repair seem easy, but it’s often unsafe. Springs, cables, and heavy doors involve serious risks. Homeowners without special tools or training could cause more damage or get hurt. Hiring a licensed expert ensures garage door repair is done safely and correctly. Professional work prevents later breakdowns and extends your door’s life. How Timely Repairs Save Money Small problems become expensive if ignored.
