Legacy garage door opener not connecting to Wi-Fi

Here are some reasons why your garage door opener is not connecting to Wi-Fi;

Inadequate Wi-Fi router

Your Wi-Fi router must meet the following specifications;

  • 802.11 b/g/n, 2.4GHz with WPA2 or WPA Security.

Additionally, you must have your Wi-Fi home network name and password available to complete the setup.

Poor Wi-Fi signal strength 

Wi-Fi signal strength in the garage depends on many factors. To test signal strength, go into the garage where the garage door opener is located and use the designated smart device to access and surf the web. If the web pages load quickly, the signal strength is strong.

The OHD Anywhere App Is Not Setup Correctly

Ensure you follow the app instructions to complete the setup of the device. Also, confirm that the correct Wi-Fi password has been entered correctly in the app.

Legacy Garage Door Opener Remote Not Working

Being unable to open your garage door due to a malfunctioning remote can be a bit of an inconvenience, especially when you get home after a long day at work or running errands.

Below are some reasons why your remote is not working;

Remote Batteries Are Depleted

Check whether the batteries have died before calling your local garage door repair professionals. Garage door remote batteries typically last about two years before needing to be replaced.

To check if your transmitter batteries are dead, try using your wall-mounted control panel to open the door. If the door responds, then dead batteries are likely the cause.

Remote Signal is Disrupted

If your remote is not working after replacing the batteries in your remote, then the signal between the remote and the opener transmitter may be disrupted. This could be because the remote is out of range or the opener receiving antennae is damaged.

Ensure that you stand within 20 feet of your garage door and attempt pressing the button. The signal won’t be strong enough to prompt the door if the remote is further away from the door.

The garage door opener antenna is broken

Check the garage door opener’s antennae and ensure it doesn’t have any excess debris buildup. It should also be pointed towards the garage door, and it isn’t broken. If the antennae appear damaged, call your local repair professionals to inspect the problem and make repairs.

The Lock Button Engaged

Another simple garage door fix is to make sure the lock button on your garage door’s wall-mounted control panel hasn’t been engaged. You could accidentally press this button while performing normal daily activities, and you can quickly disengage the door lock by pressing the lock button. Then, after unlocking the door, test the door’s operations by pressing the panel’s open button.

The Remote Needs Reprogramming

Try reprogramming your garage door remote to the opener machine. Sometimes, the signal between your opener and remote can be disrupted and need re-association with regular use.

To reprogram your garage door remote;

  • Locate, then press your opener to learn button.
  • Hold the button on your remote for three seconds.
  • Or until the garage door opener’s lights flash or the LED light on your opener blinks.

Then try using your remote to open or close your door to determine if the reprogramming was successful.

Door Control Wiring Malfunction

If the remote and wall-mounted panel method doesn’t raise or lower your door, then you may have a problem with your garage door system’s control wiring or the opener’s receiver board.

Follow the steps below to test the quality of your opener’s wiring;

  • Unplug the opener and disconnect the two wires from the motor
  • Reconnect your machine to power, then clear its memory and reprogram all remote controls
  • Unplug the device for a second time and reconnect the control wiring to the motor
  • Locate the wall-mounted controls and disconnect the wiring
  • Use your garage door opener remote to test the functionality of your door

Blown GFI

Another common reason your garage door remote control might not work is because of a blown Ground Fault Interpreter (GFI). The GFI is responsible for protecting your home from any potential electrical dangers, such as overheating.

A malfunctioning GFI would generally stop the door from functioning or might use the backup battery in some models. To remedy this issue, press the reset button on the wall outlet corresponding to your garage door. It is usually located in the garage, laundry room, or main bathroom.

How to Adjust the Sensors On a Legacy Garage Door Opener

You should start by inspecting the sensor. The inspection will help you determine if a minor adjustment will do the trick. First, check to see if the sensors have LED lights are on. If one has a lit LED while the other is flickering or entirely off, you may be able to manually adjust the unlit sensor so that it lines up again (which will result in both lights remaining lit).

Note: Also, check to see if the lens on one or both is dirty. Gently clean the debris, taking care not to bump them out of alignment, and see if that solves the problem. If neither of these adjustments works, then you can continue aligning the sensors from scratch.

How to align the sensors;

  1. Cut the Power to prevent any electrical accidents from happening while working on the garage door opener.
  2. Then loosen the sensors’ screws that hold the sensors in each of the mounting brackets using a screwdriver.
  3. Don’t remove the sensors entirely or loosen them too much. You should be able to move the sensors but only with intentional repositioning. They shouldn’t slide on their own.
  4. Reposition the sensors by sliding the sensors on each side of the door down as far as they’ll go (without unscrewing the sensor mounting bracket).
  5. Then tie a string (long enough to span the width of the garage door) around the bracket on one side so that the string will line up with the sensor lens.
  6. Pull the string taut and tie it to the other bracket in the same position.
  7. Using a level, check that the string is level. If not, adjust one or both of the sensors to bring the string up to level.
  8. Then tighten the screws to fasten the sensors into their newly aligned position.
  9. Ensure the string stays level while you tighten the screws.
  10. Finally, remove the string, turn the power back on, and close the garage door.

Legacy garage door opener light not working

When troubleshooting garage door opener light problems, apply these steps to tackle the inconvenience. Following these easy procedures won’t take you much time. However, many factors can damage the opener lights, so be sure to check every possible failure. In the end, you may need to replace the opener lights completely.

Check the Fuse Box

Before examining the light bulb, check the fuses. They might need to be replaced. A surge of electricity can both harm the fuses and cause issues with your opener lights. If the fuse needs replacement, purchase new fuses at the hardware store. Make sure to switch off the electricity before carefully installing the new fuse. Resettable fuses are helpful as they automatically help balance the current electricity, but sometimes these fuses also need to be replaced.

Check the Wires

Every once in a while, you should check the wires’ condition and check that everything is wired correctly. If this is an issue, electricity won’t be conducted properly, and you won’t be able to turn on the lights. Even replacing the bulb won’t make a difference. Wires can also be purchased at any hardware store. In addition, it’s possible to use bell wire for low voltage applications.

Check the Socket

The socket could be damaged, especially if you haven’t been conducting proper maintenance and cleaning. Rust and dust could accumulate and need to be managed. If the socket is corroded, replace it immediately, don’t wait until the lights stop working.

Replace the Bulb

To replace the bulb, start by setting a ladder next to the light housing. In this position, you’ll work most comfortably. Once you’ve climbed up the ladder, unplug the opener. Next, locate the bulb and proceed to remove each screw.

If it’s a tab model, push it out. Next, use a rag to remove the bulb by turning it in a counterclockwise direction; do this gently even if it’s very tight. The rag will protect your hand in case the light bulb cracks.

Since you’re up there, take the opportunity also to clean out the housing area and be sure to remove dust from the socket. To install the new bulb, screw it in. Put the screws back in and plug the opener back in.

Why is the garage door opener not working?

Below are some steps to help you remedy the issue;

Make sure the opener has power

Check the plug and ensure it’s fully plugged in, and try the door again. The cable could have been pulled out, tripped over, or pulled loose without anyone realizing it.

Check your breaker panel

Find your breaker panel and see if the circuit for your garage has been tripped. It’s so easy for a small power surge to trip your circuit breaker, and you do not even realize it. If it has been tripped, flip it back on and see if that solves the issue.

Align the sensors

Over time, these sensors may fall out of alignment, resulting in what seems like a broken garage door. If this is the case, you will need to align the garage door sensors to point directly at each other.

Most garage doors have a set of two sensors located at the foot of either side of the garage door. These are in place to ensure the door can’t close when something breaks the beam, effectively preventing personal injury and property damage.

Clean the photo-eye

The photo-eye on your garage door is a safety precaution that won’t allow the door to close fully if something is blocking it. It does this by shooting a beam across the bottom of the door. If the beam is interrupted, then it senses something is there and won’t work.

Check if there’s any dirt on the photo-eye, as this is often enough to stop it from working. Also, ensure that the wiring hasn’t been damaged.

Look at the springs

The springs on your garage door are a vital component of the opening mechanism. They give the door the tension it needs to be opened. Springs wear out over time, meaning that they lose their tension. In some cases, they’ll even break.

If you can’t get the door open, inspect the springs and check if they are worn out or broken. You can replace springs yourself, but it’s a dangerous job. You are better off hiring an expert to take care of this for you.

See if the door is locked

When you use a garage door opener, it should lock the door against anyone who doesn’t have the right remote control to open it. As an additional security measure, you can also lock the manually too. This is a good idea if you’re going to be away for any period. If you can’t open the door, use the key and check to see if it has been locked.

Reset your remote

One good test to do is to try opening the door with the control panel in your garage. If the door will open with this but not the remote, it’s the remote causing the issue.

You can check the batteries to see if they’re dead, but the remote will need resetting if it’s not working with new batteries. If the remote doesn’t work with new batteries or after resetting, you may need to consider purchasing a new one from your local garage door service provider.

Put the door back on the tracks

Sometimes, a garage door can be knocked off the tracks, which means it won’t open. If that’s the case, you may be able to fix the problem yourself. To do this, you’ll need to pull the door open by hand and maneuver the door back onto the tracks.

You’ll need at least two people to do this properly. If the damage is too significant, you’ll need to call an expert to repair those tracks for you.

Adjust the limit setting

This is something you’ll need to do if you find the door closes and pops open again right away. The opener’s settings may sense that the door has hit an obstacle when it has just touched the ground. In this case, the limit setting is too high and so will need adjusting.

The limit setting knob is usually located on the control panel itself. Adjust the knob in small increments until you have the door opening and closing as it should.

How to replace the battery in a garage door opener

  • Locate the battery compartment at the bottom of the control panel.
  • Open the compartment and take out the old batteries.
  • Then replace them with new batteries compatible with your garage door opener.
  • Ensure you insert them correctly. For example, the battery compartments should have the correct placement stamped into them.
  • Then test your garage door opener to see if it works.

Note: In some garage door openers, the door will slide off to reveal the batteries. But you may have to unscrew other panels to access the batteries.
