Garage door opener sensors are a convenient way to prevent injury to persons, especially children, who may be in the path of the closing or opening door. They are also a great way to prevent possible injury to pets and damage to automobiles that may be in the way. These sensors are typically installed to relay signals that tell each other if anything is in the path of the door. They are normally located near the floor, where they are subject to dirt and grime, which may hinder their proper functioning. Here, we explain to you how to fix the opener sensors.

1. Look for obstructions

Look for any objects or obstructions that hinder the proper functioning of the Garage door opener Plano sensors. This could be toys, tools, boxes or any objects on the floor that impede the proper transmission of the signals that pass between the sensors. Also, debris or dirt could be clouding the lenses. Depending on the type of the model of sensor, there may be a light that could indicate whether the signal is impeded. If signals are blocked by an object you will need to remove it. If the lenses are dirty, use a lens cleaner.

2. Check the alignment

Check if the sensors are properly aligned. If they are not, adjust the brackets that hold them in place. When you finish realigning them, you should check if the signals are transmitted properly. Or if the unit has a light it may also indicate that the sensors are ready.

3. Make sure it's getting electricity

Sometimes, it's a simple case of the sensors not getting electricity. Make sure that they are receiving the electricity that they are supposed to be getting. If the lights aren't on, check the main power on the unit. If there is no electricity you may need to contact a repair service or electrician.

4. Check the wires

Replace any damaged or frayed wires if necessary. Frayed or damaged wires can lead to the sensors not getting any electricity and, hence, not transmitting any signals. It is best to turn off the power before attempting to fix this, or call a competent service professional.

5. Open up the sensors

If the warranty on the sensors does not prohibit it, you can open them to check inside. Make sure that they are dry inside and that there are no damaged parts. Check that the parts are fused to the appropriate places. If you notice any loose connections inside the sensor may need replacement.

6. Replace the units

If nothing else works, maybe the units are defective themselves. Replace the units, if necessary. Buying a defective unit can be a frustrating situation to experience, so have new ones checked before you buy them.
