Why is sectional door repair important?

Sectional doors are not only aesthetic. They provide security for your garage or production facility and protect against precipitation and dirt. Incorrectly functioning doors can cause serious problems, such as unauthorized access or damage to property.

Understanding the features of the gate device and the main problems that arise during their operation will help you quickly deal with problems and prevent the possibility of their recurrence.

Gate Repair:Main problems and their causes

1. Problems with the lifting mechanism

One of the most common problems is the incorrect operation of the lifting mechanism. This may manifest itself in the form of difficulties in opening or closing the gate, a characteristic grinding sound or shaking. The main causes of such malfunctions are:

Worn springs. Over time, the springs responsible for balancing the gate may weaken or break.
Incorrect adjustment of mechanisms. If the gate was installed or adjusted incorrectly, this may lead to its ineffective operation.
Contamination of the guides. Dust, dirt, or ice can prevent the gate from moving normally.

2. Deformation of panels

Sometimes gate panels can become deformed due to external factors such as strong winds or accidental impacts. Causes may include:

Weather conditions. Often, prolonged exposure to moisture or freezing temperatures can damage panels.
Physical impacts. Impacts from cars or other objects can cause dents.

3. Electrical wiring and automation

If your gate is equipped with automation, there may be problems with the operation of the electrical circuit or control system. Possible causes:

Engine failure. Sometimes the cause of the failure is the engine itself or its mechanism.
Electrical failure. Voltage surges or broken wires may prevent the gate from opening or closing.

Preparing for Gate Repairs

Before you start repairs, it is important to prepare:

Tools and materials. Make sure you have the necessary tools. This may include screwdrivers, wrenches, grease for guides and springs, and spare parts if needed.
Safety. Be sure to take care of your safety. Use protective glasses and gloves when working with machinery.
Operating instructions. Read the operating instructions for your DoorHan sectional doors. They may contain specific tips and instructions for your particular device.

Stages of sectional door repair

1. Diagnosing the problem

The first step in repair is diagnosis. Make sure you understand exactly what the problem is. Try to reproduce the situation to determine what exactly is not working. Pay attention to all aspects: sound, ease of movement, position of the gate.

2. Adjusting the lifting mechanism

If your gate does not open or close properly, the lift mechanism may need to be adjusted:

Check the tension of the springs. If they appear worn or incorrectly tensioned, they may need to be replaced or adjusted.
Make sure the guides are clean and free of obstructions. Clean and lubricate the guides if necessary.

3. Gate Repair:Replacement of parts

If the panel or mechanism is badly damaged, it may need to be replaced. Contact the supplier or manufacturer to order the necessary parts. Make sure you use genuine components to ensure reliability and durability.

4. Checking the electrical system

If you have problems with electronics, check all wiring and connections. Look for damaged insulation or loose connections and replace them if necessary.

5. Testing

After completing all work, conduct testing. Check whether the gate opens smoothly and effortlessly, whether the automatic system works.

Gate Repair:Prevention and maintenance

To avoid frequent breakdowns and ensure a long service life, pay attention to their preventive maintenance:

Regular cleaning of the guides. Dirt on the guides can lead to their deformation. Inspect and clean them at least once a month.
Lubrication of mechanisms. Keep the mechanisms lubricated to prevent wear.
Check the springs. Periodically inspect the springs for wear and replace them as necessary.
Check electronics. Regularly check the condition of wiring and controls to avoid short circuits.
