SUBJECT:
HOMELINK INFORMATION
SYMPTOM:
HomeLink mirror stops working after a few days or weeks from when it was first programmed.
CAUSE:
Some garage door openers support a function called “Two Way Communication (TWC)”. The two
way communication programming is different than the standard system. If the two way
communication garage door opener is not properly programmed, the HomeLink mirror will lose its
programming after 10 operations. The HomeLink mirror buttons may open and close the garage,
but after the 10th press it will lose the programming with the garage door opener. Please contact
HomeLink customer support or go to www.HomeLink.com for more detailed information related to
HomeLink garage programming.
SYMPTOM:
HomeLink mirror intermittently will not close or open the garage door.
CAUSE: Certain LED Light Bulbs installed into the garage door opener can emit a certain frequency
that will block the signal from the HomeLink mirror, causing the garage door to intermittently not
open. Please contact HomeLink customer support for the appropriate garage door opener light bulb
selection.
NOTICE


Only troubleshoot the HomeLink mirror if there is no power to the mirror or the mirror does
not turn ON.
If there is power and the mirror turns ON, contact HomeLink customer support
1-800-355-3515 or go to www.HomeLink.com.
