4 Steps to Fix a Garage Door Radio Frequency Problem
With a little troubleshooting, your garage door opener will be back on track
Your garage door opener helps to welcome you home, so if it’s not working, it can be frustrating. If you’re having trouble getting your garage door opener to work, the radio frequency could be to blame. Garage remote controls contain radio transmitters that operate at a frequency of 300 to 390 MHz. Nearby appliances, electronics, or even airports or electrical transformers can cause the remote to malfunction.
Luckily, troubleshooting interference with your garage door opener can be a simple process that we’ll walk you through below.
How to Fix a Garage Door Radio Frequency
1. Check for Sources of Interference
Turn off or move any devices that contain radio transmitters. Then, one by one, turn them on and test the remote after each one. This process can help you identify the source of the interference. If you find the problem, either keep the device turned off until you need it or move it to a new location away from the remote and garage door.
If this process doesn’t work, you’ll have to turn the power off in your home to troubleshoot. Turn off the circuit breakers to various parts of the house, then test the garage door opener after turning each breaker back on.
2. Reset the Code
Garage door openers and exchange new codes with the garage door opening system each time you open the door. Resetting the code manually can help restore the connection between the door and the remote.
To reset it, look for a button that says “learn” on the remote control. Hold it until you see a light turn on and blink for about six seconds. Then, press the learn button again while pressing the button on your garage door keypad. Press “learn” on your additional remote controls; if your family has multiple, then press “learn” a final time. Consult your garage door opener manual for reset instructions specific to your system.
3. Upgrade Your System
Older garage door openers typically have more issues with radio frequency transmissions. Newer models offer multiple frequency settings, so you can toggle between them if something else in your home is interfering with the door opener.
There are a few different ways to upgrade your system, either by purchasing a dual-frequency opener, using a conversion kit to turn your existing system into a dual-frequency system, or installing a smart garage opener that operates with Wi-Fi.
4. Have a Professional Replace the Opener
Some garage door opener troubles are easy to fix, and you can resolve them on your own in minutes. But if you can’t track down the issue and resetting the codes doesn’t seem to work, you might invest in hiring a local garage door opener company. They may be able to help you implement a fix, but can also tell you when it’s time to replace the garage door opener entirely.
What Can Interfere With a Garage Door Remote?
Numerous items operate with radio frequencies. Any item that is transmitting on the same frequency as your garage door opener could cause issues, like making the garage close or open by itself. Here are some common things that emit radio frequencies:
Appliances
Car battery chargers
Cell phone towers
Copy machines
Computers
LED, halogen, and fluorescent lights
Motion detectors
Plug-in transformers for power tool chargers, sprinkler controls, and security systems
Wireless doorbells
Wi-Fi networks
Tracking Down the Interference
If you notice your remote isn’t working, it could be any number of electronics or appliances that emit radio frequencies. If you suspect something in your garage is causing interference, start by turning off the culprit or moving it to a different part of the house.
Unfortunately, this can either be a very easy fix or a time-consuming one. The first item you test could be the cause of the interference, and you can keep it turned off or unplugged or move it to a different part of the house permanently. But there are so many items in a garage that could be the source of interference, and tracking just the thing that is giving you grief could take hours of turning items off, moving them, and turning them back on again.
Additionally, the interference could be from a neighbor’s home or nearby airport, military base, or electrical transformer.
Cost to Fix a Garage Door Radio Frequency
If the cause of interference is easy to identify and resolve, this project will take little time and no money. Otherwise, you might need to pay to replace the remote, install a dual-frequency conversion kit, or hire a technician to help you fix the problem.
DIY vs. Hiring a Pro
The DIY cost could range widely. You might be able to fix the issue in minutes just by removing the source of interference or resetting the password to the garage door opener.
If you have an older opener and cannot find the source of interference, you might need to buy a more modern system, which can switch between frequencies. These new systems can be helpful if you have several probable sources of interference near your garage door, as these dual-frequency remote controls can switch to a different frequency as needed. Expect to spend about $120 to $290 for a new opener, which you would then install yourself.
Remember, a garage door that isn’t opening might not be because of radio frequency problems. There are many common garage door issues and repairs to consider.
If you choose to hire a local garage door installer to help with this project, the average cost is $113 to $330.
