How It Happens

Garage door openers use radio frequencies. If another device nearby uses the same frequency, it may accidentally trigger your door.

How to Fix It:

Is Someone Else Opening Your Garage Door?

Frequency Overlap Explained

Older garage door openers use fixed codes, which can be duplicated unintentionally.

Solution:

Modern systems use rolling code technology, which changes the code each time you use the remote.

• Use insulated connectors

Could the Logic Board Be Malfunctioning?

The logic board is the “brain” of your opener. If it fails, it may send random signals.

Symptoms:
