Introduction
A garage door is an essential part of any home, providing security and convenience. However, if your basculante si chiude e si riapre subito (garage door closes and immediately reopens), it can be frustrating and unsafe. This problem is more common than you think, and understanding the reasons behind it can help you fix it quickly.
This article will explain the main causes and step-by-step solutions for this issue. Whether it’s due to sensor misalignment, spring tension problems, or programming errors, we’ll guide you through the best ways to solve it. Read on to ensure your garage door works smoothly and securely!
Common Causes of “Basculante si chiude e si riapre subito”
1. Misaligned Safety Sensors
Most modern garage doors have safety sensors near the floor. If they are misaligned or blocked, they can falsely detect an obstacle, causing the door to reopen immediately after closing.
🔹 How to Fix:
- Check if the sensors are dirty or obstructed.
- Align both sensors so that the indicator lights stay steady.
- Clean the sensors with a dry cloth to remove dust or debris.
2. Garage Door Limit Settings Are Incorrect
Garage doors have limit settings that tell them when to stop closing. If the limit is too high, the door “thinks” it hit an obstacle and reopens.
🔹 How to Fix:
- Locate the limit adjustment screws on the opener unit.
- Adjust the down limit slightly to ensure the door fully closes.
- Test the door after each adjustment.
3. Obstructions in the Garage Door Tracks
If there is dirt, debris, or a small object in the tracks, the door may reverse to prevent damage.
🔹 How to Fix:
- Inspect the tracks for any small objects, dirt, or rust buildup.
- Clean the tracks and lubricate them with garage door lubricant.
4. Faulty or Worn-Out Garage Door Springs
Garage doors rely on torsion or extension springs to function properly. If they are worn out or damaged, the door may close and reopen instantly.
🔹 How to Fix:
- Check for gaps, rust, or broken coils in the springs.
- If damaged, contact a professional for replacement.
5. Issues with the Garage Door Remote or Wall Switch
Sometimes, the problem is not mechanical but electronic. A faulty remote control, wall switch, or wiring issue could send incorrect signals to the opener.
🔹 How to Fix:
- Replace the batteries in your garage door remote.
- Try using the wall switch instead of the remote.
- Reset the garage door opener by unplugging it for 30 seconds.
Step-by-Step Troubleshooting Guide
Step 1: Check the Sensors
Make sure both safety sensors are aligned and clean. If they blink, they need adjustment.
Step 2: Inspect the Garage Door Tracks
Clear any obstructions and apply lubricant for smooth movement.
Step 3: Adjust the Limit Settings
If the door reopens immediately, tweak the down limit screw slightly.
Step 4: Test the Remote & Wall Switch
Try opening and closing the door with both controls to identify the issue.
Step 5: Examine the Springs
If the door feels too heavy or uneven, call a technician for a spring replacement.
When to Call a Professional?
While some fixes are simple, certain garage door issues require expert assistance. Contact a professional if:
✔ The garage door springs are broken.
✔ The problem persists after adjusting the sensors and settings.
✔ The garage door makes loud, unusual noises.
