One: What should I do if the glass door makes a strange noise?
If you hear unusual noises coming from your glass door, don't panic. Let's identify the source of the problem. There are two common types of unusual noises that can occur with glass doors: metallic scraping sounds and explosive-sounding noises. Here's how to differentiate between these two types of noises and what steps to take:
1、Metallic Noise: The primary cause of metallic noise is mechanical defects.
Regarding metallic scraping noises, the primary observation should be whether the sliding door and door frame are rubbing against the fixed door frame, or dragging on the floor. If this occurs, adjust the gap between the sliding door and the fixed door frame, and ensure the sliding door is at the correct clearance height.
Furthermore, inspect the hinges and locking mechanisms of the sliding door for any signs of looseness, as sand or other foreign objects may be present. If found, securely fasten and clean the area, applying appropriate lubricant or transformer oil if necessary. If the noise persists, consider replacing the hinges.Additionally, remove the inspection cover to check if the rollers are rubbing against the track's inner wall. If friction is present, adjust the support accordingly to maintain a vertical position.
Subsequently, inspect the hoist and track for any collisions or damage, or check if the hoist arms and belts are contacting the control or rear cover. If any of these situations occur, replace the hoist wheels or repair the track regularly.
Furthermore, if the above-mentioned noise issues have not been resolved, you can also check for wear and tear on the motor gears and pulleys, and ensure they are at the same plane. If they are not, manual adjustment or replacement may be necessary.
2、Made a loud noise：The cause of the explosion sound is usually due to the electrical part. Automatic door electrical components generally do not have transformers, and the controller part is more prone to the cracking of electrolytic capacitors.
To address these issues, the following steps should be taken:1. Open the controller casing.2. First, check the fuse for signs of burnout, such as a burnt smell. If the fuse is blown, check the surface of the capacitors for electrolyte leakage or burnt-out capacitors.3. Before replacing any components, measure the silicon rectifier block to ensure it is functioning correctly. If necessary, replace the silicon rectifier block. For complex repairs, it is recommended to consult a qualified technician.
Two. important considerations for repairing glass door noises.
1. You can prepare specific lubricating oils or machine oils for occasional use, which can be easily handled. However, it is best to use them in small amounts, as machine oils can evaporate and produce unpleasant odors.
2. Although the glass door utilizes tempered glass, it is also susceptible to damage from excessive impact. When opening the glass door forcefully, it can also break. Therefore, when maintaining or repairing the glass door, it is important to carefully control the force and to apply protective strips to the door to prevent damage.
3. When repairing glass doors, it is advisable to engage specialized professionals. Many individuals lack familiarity with the hardware components of glass doors, and have not performed adjustment or replacement work. This can potentially lead to further damage.
