Garage Door Closing Issues — We Find the Cause Fast

A garage door that won't close is a security risk — your house is wide open to the street, your tools and bikes are visible from the driveway, and the heat is leaving the garage. Don't leave your home exposed. POCO Garage Doors provides same-day diagnosis and repair across every Tri-City neighbourhood, and most closing problems are fixed on the first visit because our trucks carry every common part.

Door Stuck Open

Door Won't Come Down? Don't Leave It That Way Overnight

A garage door stuck open is the #1 reason we get called for an after-hours visit. Whether the door tried to close and bounced back up, the remote stopped working, or the wall button does nothing, the result is the same: your house is open, the heating bill is climbing, and anyone on the street can see straight into the garage.

Most stuck-open calls trace back to one of three things — misaligned safety sensors, a close-limit switch out of range, or a broken spring throwing the opener into safety mode. We carry the parts for all three on every truck and most calls in Coquitlam, Port Coquitlam and Port Moody are diagnosed and resolved inside an hour.

Safety Sensors • #1 Cause

Photo-Eye Safety Sensors — Where 80% of Closing Problems Start

Every garage door opener built after 1993 has a pair of photo-electric sensors mounted six inches above the floor on each side of the door. They project an invisible infrared beam across the opening. If anything — a leaf, a bike pedal, a misaligned bracket, even a spider web — breaks that beam, the opener will refuse to close the door.

When the sensor lights are steady green and amber, the system is happy. When one of them is flashing or off, the beam is broken or the sensors are out of alignment. A 3 mm twist on the mounting bracket is enough to throw them off. We realign, clean the lenses, replace any cracked sensor housings, and re-test the auto-reverse on the same visit.

Quick at-home check: with the door open, look at the two small sensors near the floor. Both indicator lights should be on and steady. If one is blinking or dark, gently twist the bracket until both lights go steady — sometimes that's the whole repair. If they won't stay aligned, the brackets are bent or the wiring has been pinched and you need a technician.

The Six Most Common Reasons A Garage Door Won't Close

Misaligned safety sensors — The most common cause. If the photo-electric sensors near the floor are blocked, dirty, or knocked out of alignment, the door will not close. The indicator light flashes or goes dark.
Close-limit switch needs adjustment — If the door reverses just before reaching the floor, the limit switch is telling the opener the floor is higher than it actually is. A 30-second calibration fixes it.
Obstacle on the floor or track — A leaf, a coiled garden hose, or even a small piece of debris in the door's path will trigger a safety reversal mid-travel.
Damaged or bent track — Dents in the vertical or curved track cause the door to bind on its way down and the opener reads the resistance as an obstruction.
Broken spring or cable — Uneven tension makes the door descend crooked, which throws the opener into safety mode. You may hear a loud bang when this happens.
Worn opener gears or logic board — A failing main gear or a corroded logic board will close the door inconsistently. We diagnose with an amp-draw test and replace only what's worn.

What Happens On A Same-Day Service Call

1. Sensor & Alignment Check

We start at the photo-eyes — the cheapest, fastest fix. Realign, clean lenses, replace housings if cracked, verify both LEDs go steady.

2. Limit & Force Calibration

Set close-limit and down-force per CSA standard so the door reaches the floor without bouncing or hitting hard.

3. Track & Spring Inspection

Walk both vertical tracks for dents or play; check spring balance and cable wear — the silent causes of a reversing door.

4. Auto-Reverse Test

Place a 2″ block under the door and close it. The opener must reverse on contact. We retest before leaving every job.
