How to change garage door opener frequency?


Changing the frequency of a garage door opener is a common task that homeowners may need to undertake. Whether it’s due to interference from other devices or a desire to enhance security, adjusting the frequency can help ensure smooth operation and prevent unauthorized access. In this article, we will explore the steps involved in changing the frequency of a garage door opener.

Understanding Garage Door Opener Frequency

Before diving into the process of changing the frequency, it’s important to understand how garage door opener frequency works. Garage door openers typically operate on a specific frequency, often in the range of 300-400 MHz or 800-900 MHz. This frequency allows the remote control to communicate with the opener, triggering the door to open or close.

Identifying the Frequency of Your Garage Door Opener

To change the frequency, you first need to determine the current frequency of your garage door opener. There are a few ways to do this:

1. Check the manual: The user manual that came with your garage door opener should provide information about the frequency. Look for a section that details the specifications of the opener.

2. Look for labels: Some garage door openers have labels on the motor unit or remote control that indicate the frequency. Check these labels for any relevant information.

3. Contact the manufacturer: If you’re unable to find the frequency through the manual or labels, you can contact the manufacturer directly. Provide them with the model number of your opener, and they should be able to assist you in identifying the frequency.

Changing the Frequency

Once you have identified the current frequency of your garage door opener, you can proceed with changing it. The process may vary depending on the specific model and manufacturer, but here are the general steps involved:

1. Access the motor unit: Locate the motor unit of your garage door opener. This is usually mounted on the ceiling of the garage. Use a ladder or step stool to reach it safely.

2. Locate the frequency adjustment button: Look for a small button or switch on the motor unit that is labeled as the frequency adjustment button. It may be located on the back or side of the unit.

3. Press the frequency adjustment button: Press and hold the frequency adjustment button for a few seconds until the indicator light on the motor unit starts blinking. This indicates that the opener is in programming mode.

4. Program the new frequency: Once the indicator light is blinking, press the desired button on your remote control that you want to use to operate the garage door. The indicator light should stop blinking, indicating that the new frequency has been programmed.

5. Test the new frequency: After programming the new frequency, test the remote control to ensure that it is working properly. Press the button you programmed and observe if the garage door responds accordingly.


Changing the frequency of a garage door opener is a straightforward process that can be done by following a few simple steps. By identifying the current frequency and accessing the motor unit, homeowners can easily program a new frequency to enhance the security and functionality of their garage door opener.
