Why Does Your Garage Door Opener Opens But Doesn’t Close?

Common Culprits:

1. Sensor Misalignment:

One of the primary reasons for a garage door opener’s erratic behavior is sensor misalignment. Sensors are crucial components that ensure the door doesn’t close when there is an obstruction. If they are not aligned properly, the door may interpret it as an obstruction and remain open.

2. Obstructed Sensor Path:

Over time, the sensor path can accumulate dirt, cobwebs, or other debris. This obstruction can disrupt the communication between the sensors, causing the door to open but not close.

3. Faulty Wiring:

Wiring issues can also contribute to this problem. Examine the wires connected to the sensors and the opener for any signs of damage or disconnection. Faulty wiring can disrupt the signal and prevent the door from closing.

4. Limit Switch Problems:

The limit switch determines how far the garage door should move in both opening and closing directions. If this switch is improperly set or malfunctioning, it can result in the door only opening and not closing.

5. Remote Control Malfunction:

Sometimes, the issue may be with the remote control itself. Check for weak batteries or reprogram the remote to ensure it is sending the correct signals to the garage door opener.
