How to Fix a Garage Door That Won’t Close All the Way
A garage door that won’t close all the way is one of the most frustrating problems a homeowner can face — and it’s also a security risk. If your door stops partway down, reverses, or won’t move at all, there are several possible causes. Here’s how to diagnose and fix the problem, and when to call Kiki Garage Door for professional help in the Redmond area.
1. Safety Sensor Obstruction or Misalignment
The most common reason a garage door won’t close is the safety sensors. These are the two small units at the bottom of the door tracks — one sends an infrared beam, the other receives it. If something is blocking the beam or the sensors are out of alignment, the door won’t close as a safety precaution.
Fix: Check for any objects blocking the sensor path. Clean the sensor lenses with a soft cloth. Make sure both sensors are pointing directly at each other — if the indicator lights are blinking, the sensors are misaligned. Loosen the wing nut, realign the sensor, and retighten.
2. Limit Switch Needs Adjustment
The limit switch tells your opener how far the door should travel when opening and closing. If it’s set incorrectly, the door may think the ground is an obstacle and reverse.
Fix: On most openers, there are two adjustment screws labeled “UP” and “DOWN” (or “CLOSE”). Turn the “DOWN” adjustment screw a small amount clockwise to increase the closing distance. Test after each small adjustment.
3. Broken or Damaged Springs
If one or both torsion springs are broken, the door may not have enough counterbalance force to close completely. A broken spring is a serious issue — the door can be very heavy and dangerous to operate manually.
Fix: Do not operate the door. Call Kiki Garage Door immediately at (425) 470-5806. Spring replacement should always be done by a professional.
4. Track Obstructions or Damage
If the garage door tracks are bent, dirty, or have an obstruction, the door may bind and stop before reaching the ground.
Fix: Inspect the tracks for visible dents, debris, or gaps. Clear any debris with a cloth. Minor track misalignment can sometimes be fixed by loosening the track mounting bolts and tapping the track back into alignment with a rubber mallet. Significant damage requires professional track replacement.
5. Worn or Frayed Cables
Garage door cables run from the bottom corners of the door to the spring drum. If a cable is frayed, loose, or snapped, the door won’t close evenly and may bind or stop.
Fix: Do not attempt to repair cables yourself — they’re under high tension and can cause serious injury. Call Kiki Garage Door for professional cable repair.
6. Dead Remote Battery or Signal Interference
Sometimes the simplest answer is correct — a dead battery in your remote or interference from nearby electronics can prevent the door from receiving the close command.
Fix: Replace the remote battery. Try closing from the wall-mounted button. If the wall button works but the remote doesn’t, reprogram the remote or replace it.
