Common Sensor Issues

Like any component, garage door sensors can experience problems over time. These issues include:

  • Broken wires or wiring damage
  • Sensor misalignment
  • Debris or objects blocking the infrared beam
  • Normal wear and tear over years of use
  • Power supply problems to the sensor

Fortunately, many of these sensor woes have an obvious solution that a garage door expert can quickly identify and repair.

The Sensor Lineup

Garage doors typically use one of three main sensor types to detect obstructions:

Reed Switch Sensors 

These use an electromagnetic field to monitor the door’s open/closed position. As the door moves, the switch is activated or deactivated by a magnet mounted on the door. Reed switches are simple yet effective sensors found on many residential garage door openers.

Infrared Door Sensors 

The most common type, infrared sensors create an invisible beam across the garage floor about 6 inches above the ground. This infrared beam continuously monitors for any objects, pets, or people that pass through to automatically reverse the door’s direction. Proper alignment and clean lenses are crucial for these photo eye sensors to work.

Rolling Switch Sensors 

Mounted directly on the garage door itself, these sensors use a switch that is tripped when the door encounters an obstruction while closing. The door will then automatically reverse its direction to prevent damage or injury. While not as advanced as photo eyes, rolling switches provide reliable sensor capability. No matter which type of sensor your garage door utilizes, it’s essential to have it functioning properly for safety.

The Repair Process

When your garage door sensor acts up, the first step is a thorough inspection:

  • Check the power supply to the sensors
  • Inspect sensor wires for damage or breaks
  • Test push bar and LED indicator lights
  • Clean sensor lenses with a soft cloth
  • Realign sensors if the positioning is off

Our certified technicians take care to examine every component. If wiring issues are discovered, we can make repairs or replace faulty wires and parts as needed, such as:

  • Replacing broken sensor wires
  • Reconnecting wires to proper terminals (black to sensor, white to white terminal block using a wing nut)
  • Installing an entirely new sensor if excessive damage

In some cases, the complete sensor unit may need replacement due to normal wear over time or if the wiring is too damaged to repair cost-effectively.

How do I fix my garage door sensor?

There are a few basic troubleshooting steps: check the sensor wires for any damage, ensure the lenses are clean, and confirm the sensors are properly aligned. If those don’t resolve the issue, it’s best to call a professional garage door repair service to inspect and fix the sensors.

How much does it cost to replace garage door sensors?

Replacement sensor costs can range from $50-$200 depending on the sensor type and brand. Professional installation fees are usually $75-$150 on top of the part cost. Getting a quote is recommended as prices can vary.

Can you replace garage door sensors?

Yes, garage door sensors can absolutely be replaced if they are malfunctioning or damaged beyond repair. Replacement is recommended over attempting complex wiring or alignment repairs yourself.

How do you test a garage door sensor?

Testing is simple – with the garage door closed, wave an object like a piece of cardboard or broom through the sensor’s infrared beam path. The door should automatically reverse direction when the beam is obstructed if working properly.

How do I know if my garage sensor is bad?

Signs of a bad garage door sensor include the door not reversing when obstructed, the sensor lights not illuminating, or the door operating erratically. You may also hear a clicking noise from the motor attempting to reverse unsuccessfully.
