Three common maintenance issues of electric sliding doors

Release date:2026-03-17 14:03:43

The electric telescopic door is an efficient and cost-effective access control device. It has now been widely adopted in various enterprises and institutions. Today, I will talk to you about the maintenance issues related to the electric telescopic door. Today, I will introduce three issues.

Issue One: How to solve the problem of not being able to open or close?

Answer: The biggest problem that the electric telescopic door encounters is that it cannot be opened or closed. When such a problem occurs, the maintenance of the electric telescopic door should first check whether there is an electricity supply and whether the fuse is burned out. If the fuse breaks, a comprehensive inspection must be carried out. Generally speaking, if it cannot be opened or closed, it is usually a problem with the circuit. Therefore, it is necessary to measure whether the red, white, and yellow leads are connected. The main thing is to see where the problem occurs in the three lines.

Issue Two: How to solve the tremor phenomenon during the operation of the barrier gate?

Answer: During the operation of the barrier gate, there are often some tremor phenomena, and sometimes they become more and more serious. For the occurrence of this problem, the maintenance of the electric telescopic door mainly needs to figure out the cause. For example, whether it is caused by the length of the gate rod not being proportional to the spring tension. If the lowering of the gate does not tremor, but the raising does, it indicates that the spring elasticity is too strong. Of course, if the opposite is true, then it indicates that the spring elasticity is insufficient. It should be tightened appropriately.

Issue Three: How to solve the automatic reverse phenomenon of the double-door?

Answer: Another common problem encountered in the maintenance of the electric telescopic door is that the double-door has an automatic reverse phenomenon. The cause of this problem should be the poor anti-interference ability of the infrared or the incorrect action caused by the photoelectric induction. The solution to this problem is usually to adopt coding or replace the pcb board. Of course, if there is a problem with the infrared, the best way is to replace it to ensure normal use. The above are several common methods for troubleshooting and repairing the malfunction of telescopic doors. If the malfunction of the telescopic door cannot be resolved, it is best to seek professional repair services from a specialized company.
