Question:

Electric garage door why always open their own

My home electric garage door always opened their own, and every time he looked down at the inside of the light after the black light to leave, but there are 2 times, the first two days a gate open? What is the reason for this?

Answer:

May be remote control channeling code, two with the same brand of garage doors within 30 meters away, after the installation of the garage door remote control input password, the information is easy to install the garage door remote control received. The first installment of the garage door when the owner of the garage door, after the installation of the garage door to follow the opening, and the first installation of the garage door closed, after the installation of the garage door is not closed. The problem is solved when the password of the remote control of the two garage doors is reset.
Repeatedly press the switch caused. Remote response speed is not timely or program error. Resulting in poor response time on the program. When you press once, but the door did not reflect, and then press once, very prone to such a program error.
Should be open the door of the problem: 1) first look at the remote control is not a fixed code, if it is necessary to adjust the code, fixed code will occasionally string code phenomenon. 2) If the remote control is a rolling code, there should be two possible: 1 is a single chip chip itself, poor anti-jamming performance, the interference signal, mistaken for the door signal. 2 kinds of single-chip program itself can not be stable operation, this situation door machine manufacturers should be able to find earlier, should not enter the market. Unless it is a new brand, has not been a wide range of applications, the problem is not found in time. 3) Another note is not every time the door will open their own, if it is for the automatic closing function, your motor line reversed, swap on the line. But I think this is unlikely. Now buy a door machine is cheaper, I suggest or for a forget.
There may be problems with the shock circuit, when there is power outage and power, causing the main control board drive door action, this time can be used repeatedly power-on Way to experiment which part of the circuit problem, to improve this part of the reset circuit and CPU program and the oscillation circuit, can achieve the purpose of solving this problem.
