Commonly Asked Questions and Solutions
Q: What if my remote won’t program?
A: Ensure your opener is plugged in and the electrical circuit is live. Check for any interference from nearby LED lights, which can sometimes affect the signal. Reset the opener and try programming again. If the light bulb is causing interference then you may want to consider using an LED or rough service bulb that is made for garage door openers. Read more about them here.
Q: The ‘Learn’ button doesn’t seem to work. What should I do?
A: Unplug the opener for a few minutes, then plug it back in. If the ‘Learn’ button still isn’t working, it may be a circuit board issue. Refer to your manual for warranty information or contact a professional.
Q: My remote has a very short range. How can I fix this?
A: First, replace the battery in the remote. If the range doesn’t improve, remove any potential signal obstructions or interference sources. If the issue persists, the remote may need to be replaced. The bulb in your operator may be causing interference. Read more about the bulbs that we recommend here.
Q: How do I erase all remote controls from my opener?
A: Press and hold the ‘Learn’ button until the LED goes out (about 6 seconds). This will clear all programmed remotes. You will need to reprogram the remotes and keypad (if you have one) that you wish to use.
Q: My door won’t close and the lights are flashing. What’s wrong?
A: This usually indicates an issue with the safety sensors. Ensure they are aligned correctly, the lenses are clean, and there are no obstructions. There also could be other issues causing the problem. Refer to the troubleshooting guide in the back of the opener manual.
