Garage Door Sensor Repair
Garage door sensors are small but essential pieces of safety equipment on your garage door system. Thus, homeowners and property owners often overlook them until something goes wrong.
Garage door sensors typically use a combination of infrared and radio wave technology to detect the garage door’s position and ensure that it is safe to close. The sensor system consists of two parts: a transmitter and a receiver. The transmitter is usually mounted on the garage door, and the receiver is installed on the wall near the garage door opener.
The sensor prevents the garage door from closing once it detects a person, pet, or object is in the way.
Common Reasons a Garage Door Sensor Stops Working
There are several common reasons why a garage door sensor may stop working, including:
- Obstructions: When an object blocks the garage door’s path, it can trigger the sensors and prevent the door from closing.
- Misalignment: If the sensors are not correctly aligned with each other, the infrared beam may not be able to pass between them. Therefore, the garage door will not close or reverse direction. This can happen if the sensors are bumped or moved out of place. Remember that both sensors should have their LED lights illuminated if there’s proper alignment.
- Power Supply: If the garage door sensor is battery-operated, the batteries may need to be replaced.
- Sunlight interference: If the sun shines directly on the sensors, it can cause them to become confused. The garage door sensors will send mixed signals, leading to problems with the garage door’s operation.
- Excess Moisture: If you live in a place with high humidity levels, your garage door sensors may encounter difficulty operating correctly.
- Wear and Tear: As a result of constant use, your garage door sensors can deteriorate, especially if they were installed years ago.
- Dirt and debris: Dirt, pollution, car exhaust, dust, and other debris can accumulate on the sensors’ lenses. This blocks the infrared beam and prevents the garage door from closing properly.
- Electrical problems: Electrical issues, such as a faulty wire or a malfunctioning circuit board, can cause the sensors to stop working altogether.
Signs Your Garage Door Sensor Is Broken
A broken garage door sensor can manifest in a number of ways. Some of those are:
- The garage door won’t close. Your garage door refuses to close regardless of what you try. It goes down to close, then stops mid-way and goes back to its original position or gets stuck halfway from opening or closing. There can be a problem with the sensors not working adequately. However, it doesn’t always mean your garage door sensors need to be replaced. Sometimes it just needs some cleaning as they accumulate dirt over time.
- The garage door light flashes. Many garage door sensors have an exterior LED. The screws that keep your garage door sensors in place can loosen over time, causing misalignment between the sensors. If you encounter a blinking light, it tells you that the sensors are not functioning. However, tightening the screws to resolve this issue may be all you need to do.
- The sensors are visibly damaged. If you can see physical damage to the sensors, such as cracks or broken wires, they may need to be repaired or replaced. Thus, your best option is to contact a certified technician to assess the problem.
- The garage door sensor is beeping. Some garage door sensors have an audible alarm that beeps when not working correctly.
If you notice any of these signs, addressing the issue as soon as possible is crucial to prevent further damage or safety hazards. Call a professional garage door repair technician to diagnose and fix the problem. Remember, attempting to repair it yourself may just cause more severe damage to your garage door sensors, becoming a danger to you or your loved ones.
Garage Door Sensor Repair Services
When your garage door isn’t working correctly, there’s a possibility that one of the safety sensors is the cause. Thus, you may need to do some checking on your own by following these three steps:
- Take a look at the sensors. Are they obstructed in any way? If so, remove the obstruction and see if that solves the issue.
- Check if the sensors are correctly aligned. They should be pointing directly at each other with nothing in between them. A red or green light indicates whether or not the sensors are aligned.
- If the sensors look aligned, inspect the connections and wiring. Check that all of the wires are securely connected, and there is no sign of damage. If everything looks to be in order, you may need to replace the batteries in the sensors.
Suppose your garage door is not operating as usual after performing all these checks. In that case, you need a qualified and experienced garage door repair technician who can diagnose and fix the issue. To choose the repair service that can help you best, try the following:
- Ask for recommendations. Ask friends, family members, or neighbours. They may recommend a garage door repair technician they trust.
- Check online reviews. Search for garage door repair companies in your area. Read reviews from previous customers to get an idea of their reputation and level of service.
- Verify licensing and insurance. Ensure the repair technician is licensed and insured to perform garage door repairs in your state.
- Get a written estimate. Before agreeing to any repairs, get a written estimate that outlines the cost of parts and labour.
- Ask about warranties. Inquire about any warranties or guarantees that come with the repair work.
- Schedule the repair. Once you have found a reputable garage door repair technician, schedule the repair work at a convenient time.
Remember, safety should always be your primary concern. If you don’t feel comfortable or have the expertise needed to perform repairs on your garage door system, it is best to call a professional technician to do the job in a safe and correct manner.
