If your garage door goes up but will only come down when you work the wall switch, you probably have misaligned safety sensors. Check to see if the small light is lit up when you use the remote and there’s nothing blocking the door. If there’s no light, you likely need garage opener repair and will need to replace or realign the sensors. Sometimes, it’s just a matter of direct sunlight being exposed to your sensor eyes, which can cause them to misbehave. If sunlight is the problem, give the sensor some shade, perhaps with a piece of cardboard or small piece of wood.
Could the Problem Be a Dirty Sensor?
Occasionally a sensor will stop working because it’s too dirty. Apply a soapy rag and wipe off the sensor. See if this allows the sensor to reconnect.
You may also just need to realign the safety sensor. You need to make sure the sensor is in a position that can more easily pick up the signal.
New sensors generally go for about $40. Remember that sensors are brand specific. You need to buy a sensor designed to work with your opener.
How to Repair Wall Switch/Wires
Sometimes your remote works fine but the wall switch doesn’t. This means either the wall switch needs replacing or you need new wires. That sounds complicated, but trust us, this is a fairly easy garage door opener repair. Unscrew the wall switch from the wall and touch the two wires together. They’re low voltage, so don’t worry about shock. If the door works, you’ve got a bad switch that will need replaced. You can get a new one for about $15. If the door doesn’t work, you’ll need to replace the wire. You’ll need to install 18- to 22-gauge wire for this garage door repair.
