North Vancouver Garage Door Guide
How to Align Garage Door Sensors Safely
Misalignment often causes a door to reverse or refuse to close from the remote. Because sensor lights and colours vary by brand, use the model manual to interpret indicators.

Quick answer
Garage door sensors align when both photo eyes face each other across the opening at the correct height and their indicator lights show a stable connection. Clean the lenses, remove obstructions, and make only gentle bracket adjustments; do not bypass the sensors.
What to understand first
A small bracket movement can break the beam
Storage bins, bikes, brooms, or foot traffic can knock a sensor out of position.
Dirty lenses mimic misalignment
Dust, spider webs, water spots, and road grit can scatter the beam.
Sunlight and reflective surfaces can interfere
Strong low-angle light may affect one sensor at certain times of day.
Damaged wiring is not an alignment problem
Loose staples, cut insulation, corrosion, or intermittent lights call for repair rather than repeated aiming.
Safe checks and next steps
- Close the door area to traffic. Keep people, pets, and vehicles away while working near the opening.
- Clean both lenses gently. Use a soft dry cloth; avoid harsh cleaners that leave residue.
- Check that brackets are secure. A loose bracket will drift out of alignment again.
- Aim the sensors toward each other. Make small movements while watching the indicator lights described in the manual.
- Test the reversal system. Use the manufacturer’s approved test method and never place a person in the door path.
Do not loosen, wind, cut, or reposition garage door springs, cables, drums, bottom brackets, or loaded track hardware. Stop if the door is heavy, crooked, partly off track, or moving unpredictably.
North Vancouver conditions to consider
Rain, splashback, and debris from wet driveways can soil low-mounted photo eyes. Regular gentle cleaning is useful in North Vancouver’s damp months.
For adjacent guidance, review cleaning photo-eye lenses and door reversal troubleshooting.
When professional service makes sense
Call for service if lights flicker when wires move, brackets are bent, sensors are physically damaged, or the door still will not close after cleaning and careful alignment.

Frequently asked questions
Can I tape the garage door sensor button down?
No. Bypassing or defeating the safety system creates a serious hazard.
Why is one sensor light amber and the other green?
Different colours can be normal on some systems. Check the exact opener manual.
Can sunlight cause sensor problems?
Yes, direct low-angle sunlight can sometimes interfere. Proper alignment and approved shielding may help.
