Up and Down Garage Doors diagnoses and repairs garage doors that close then immediately reopen across Metro Vancouver BC, addressing misaligned photo-eyes, incorrect travel limits, and worn torsion springs on the region’s mix of older single-panel and modern sectional doors.
Why Does My Garage Door Close Then Reopen?
In Metro Vancouver’s damp climate, photo-eye sensors fog or collect condensation on cool mornings, especially in Richmond, Delta, and North Shore homes near the water. Salt-laden coastal air can corrode sensor lenses and wiring over time. Misaligned brackets from seasonal ground shift, which we see on some older Metro Vancouver homes — break the infrared beam. Incorrect down-limit settings cause the door to hit the floor, detect resistance, and reverse. Broken or fatigued torsion springs on heavier insulated doors (common in newer Surrey and Langley builds) create uneven tension that triggers the opener’s force-sensitivity reversal.
What Role Do Photo-Eye Sensors Play in False Reversals?
Photo-eyes mounted 4–6 inches above the floor on either side of the opening must maintain an unbroken beam. In Metro Vancouver, morning dew and winter condensation coat the lenses, scattering the beam. Spider webs in corner-mounted sensors — frequent in detached garages backing onto greenbelts in Coquitlam and Port Moody — produce the same effect. We clean, realign, and if needed replace sensors with models rated for high-humidity environments.
How Do Travel Limits Cause the Door to Reopen?
The opener’s down-limit tells the motor when to stop. If set too far, the door drives into the concrete floor; the opener senses excess force and reverses. On older chain-drive openers in 1970s–1990s Richmond and Burnaby ranches, limit screws loosen over time from vibration. On newer belt-drive units in Langley and Maple Ridge infill homes, electronic limits drift after power outages. We recalibrate limits to stop the door 1/4 inch above the seal.
Can Worn Springs Make the Door Reverse?
Yes. A door with one broken spring or two fatigued springs feels heavier on one side. The opener’s force sensor interprets the imbalance as an obstruction and reverses. This is more common on heavier insulated double-car doors. We replace springs in matched pairs and rebalance the door so the opener sees consistent resistance.
Frequently Asked Questions
Why does my garage door close halfway then go back up?
Mid-travel reversal usually means the photo-eye beam is interrupted by a misaligned bracket, debris on the track, or a sensor lens fogged by humidity. We inspect the full beam path, clean lenses, tighten brackets, and verify the opener’s force setting matches the door weight.
Will adjusting the force setting fix the problem?
Turning up the force knob masks the symptom but risks damaging panels, bending tracks, or creating a safety hazard. We find the root cause — sensor alignment, limit setting, spring balance, or roller friction — and correct it so the factory force setting works safely.
Do you replace photo-eye sensors on older openers?
Yes. We stock universal sensors compatible with Chamberlain, LiftMaster, Craftsman, Genie, and Legacy units common in Metro Vancouver homes. If the opener is over 20 years old and parts are unavailable, we discuss full opener replacement options.
How quickly can you respond in Metro Vancouver?
We run trucks from Richmond across Metro Vancouver — Vancouver, Burnaby, New Westminster, Surrey, Delta, North Vancouver, Coquitlam, Port Moody, Langley, and Maple Ridge. Same-day service is typical for calls before 2 PM.
What brands of openers and parts do you service?
We service LiftMaster, Chamberlain, Craftsman, Genie, Linear, Marantec, Sommer, and Legacy systems. We use manufacturer-spec springs, cables, rollers, and sensors — no universal substitutes that wear faster in our wet climate.
Is it safe to use the door while it’s reversing?
No. A reversing door can pinch fingers, damage vehicles, or fall unexpectedly if a spring fails during the cycle. Disconnect the opener (pull the red emergency release) and operate manually only if the door stays in place when stopped halfway. Call us before using the opener again.
