The modern-day garage door opener comes with an array of safety features, one of which is the use of safety sensors. However, there can be instances when the garage door refuses to close and the opener blinks ten times. Through this guide, we aim to demystify the troubleshooting process to ensure your garage door is back in operational mode.

Understanding the Blinking Signs

The mechanism behind the blinking is quite straightforward. The garage door opener blinks ten times to indicate an issue with the safety sensors. These gadgets employ an invisible infrared light beam to detect obstructions in the garage door’s path. A common problem could be a blocked or misaligned sensor, defective wiring, or the sensors themselves being faulty.

Step 1: Clearing The Obvious Obstructions

Begin by inspecting the garage door’s pathway for any obstruction. Removing the object that obstructs the sensors might solve the problem instantly. If nothing appears to block the sensors, checking their alignment should be the next step. A minor bump could misalign the sensors, causing the blinking.

Step 2: Checking Sensor Alignment

The safety sensors comprise a sending sensor (yellow light) and a receiving sensor (green light). The sending sensor transmits the infrared beam to the receiving sensor. Ensure the yellow light is on and check for the green light on the receiving sensor. If the green light is off, realign the sensors until the green light turns on and try closing the door.

Step 3: Delving into Error Codes

If the issue persists, look for error codes on the LED troubleshooting light on the motor unit. These error codes vary from a common chain-drive garage door opener to belt-drive models. Understanding these error codes is essential as they provide insight into the underlying issue, whether it’s a wiring fault, a misalignment, or sensor defect.

Step 4: Investigating Wiring and Connections

Check the wiring between your motor unit and the sensors for visible damage. Though not all wiring is accessible, especially if routed through walls, ensure to inspect what’s visible and repair any broken or damaged wiring.

Step 5: Testing The Safety Sensors Directly

If the problem remains unresolved, testing your safety sensors directly at the motor unit is advisable. This test helps determine if there are defective sensors or a break in the wiring that’s not visible. The procedure involves disconnecting the sensors, stripping the wires, and reconnecting them directly to the motor unit for testing.

Step 6: Replacing Defective Components

Should the testing reveal defective sensors, replacing them is the next logical step. If the issue lies within the wiring, replacing the existing wires might resolve the problem.
