Share post:

Welcome to MS Garage Door Services, your expert in garage door repairs, installations, and maintenance. Today, we’ll explore how to bypass garage door sensors, an often requested topic for troubleshooting and repair needs. This guide provides a detailed look into the reasons for bypassing sensors, the types of sensors available, step-by-step instructions, and answers to common questions.

Understanding Garage Door Sensors

Garage door sensors are critical safety features required by law under the U.S. federal safety standards. These sensors prevent the door from closing if an object or person is detected in its path. They are usually located on both sides of the door at about six inches above the ground and consist of two main types: infrared sensors that detect objects in the door’s path and mechanical sensors that sense resistance when hitting an object.

Reasons for Bypassing Sensors

Occasionally, sensors may malfunction due to misalignment, wiring issues, or dirt accumulation, necessitating a temporary bypass to allow for door operation while awaiting professional repair.

Types of Garage Door Sensors

Garage door sensors vary depending on whether they are used in residential or commercial settings.

Residential Garage Door Sensors

  • Infrared Sensors: Most common, using an invisible beam to detect obstacles.
  • Mechanical Sensors: Less common, these activate upon physical contact with an object.

Commercial Garage Door Sensors

  • Photo Eyes: Similar to residential infrared sensors but built to withstand heavier usage and harsher environments.
  • Safety Edges: Integrated into the bottom of the door, these sensors stop or reverse the door upon contact.

Price Range for Garage Door Sensors

Here is a detailed table displaying various types of garage door sensors, their typical usage, and price ranges:

Sensor Type Application Price Range
Infrared Sensors Residential $20 – $50
Mechanical Sensors Residential $30 – $60
Photo Eyes Commercial $40 – $100
Safety Edges Commercial $50 – $200

How to Bypass Garage Door Sensors

Bypassing garage door sensors should only be a temporary solution until professional help can restore the normal safety features. Here are detailed instructions for bypassing different types of sensors:

  1. Locate the Sensors: Identify the sensors at the bottom of the door tracks.
  2. Shut Off Power: Always turn off power to the garage door opener to avoid electrical hazards.
  3. Disconnect Sensors: For infrared sensors, disconnect the wires leading to each sensor. For mechanical sensors, you may need to disengage the sensor from where it is attached to the door.
  4. Bridge the Connection: Connect a jumper wire between the sensor terminals in the opener unit. This simulates the closed circuit needed for operation.
  5. Test the Door: Carefully test the door to ensure it operates. Watch closely for any obstructions.
  6. Restore Power: After testing, restore power to the system.

Always remember, bypassing sensors removes critical safety features, and the door must be monitored closely while in this state.

Safety Precautions

  • Never leave the garage door unattended when sensors are bypassed.
  • Always ensure no persons or objects are in the path of the moving door.
