Garage door wireless remote control common problems and troubleshooting methods:

Wireless remote control When the button is pressed, the garage door remote indicator does not light, or the remote control indicator is dark

Remote control battery battery is no electricity, or battery power is low, replace the battery (note positive and negative polarity), if the indicator light is still not bright, check the button for damage, oxidation (if some buttons have reaction, Great possibility for the key damage, there may be damage to the diode on the circuit), no longer possible the remote control is damaged.

Wireless remote control When the button is pressed, the host does not respond

First check the wireless remote control is the original remote control, if there are two wireless remote control to check one of the remote control has a reaction, another remote control does not respond, may this remote control password is lost, press the learning button, LED lights Flashing, press the same button twice the remote control, if the LED lights flash quickly, that learning success, if the LED lights continue to slow flash, that learning is not successful, if the study is successful, still can not remote control, Or may be a problem for the main control board, if repeated learning is not successful, may be remote control damage; if any remote control can not be remote control, and learning is not successful, may receive board problems, check the receiver board sensitivity and other Related circuit.

Password loss is less likely, but can not completely eliminate the code, if a host often lose the password, you need to replace the decoding circuit.

When the garage door is running, the remote control by the garage door can not stop it or the remote control stops at a distance

When the garage door is running can not stop it, mainly due to the motor running a large number of strong electromagnetic waves, interference to receive part of the circuit power supply, the power generated a lot of clutter, so that the remote control distance becomes very close, you can take the following Method to solve:

1, in the receiving circuit and the main control circuit of the power and ground beads, magnetic ring, inductors and other devices, and more filter capacitors and other filter.

2, if you can receive the circuit and the main control circuit shield will have a better effect.

3, the receiving board and the main control board installation location as far as possible from the motor.

4, in the motor poles on the installation of filter and pulse components, try to shield the motor up.

5, the receiving antenna with a shielded cable pulled out, away from the motor a little bit far away, favorable to increase the distance from the remote control.

These measures can help improve the remote control of the stop distance, but in general, stop the remote control distance than the start of the remote control distance.

Wireless remote control remote control distance

Wireless remote control distance gradually, under normal circumstances for the wireless remote control battery power gradually less, replace the wireless remote control dedicated 12V battery can, if still can not solve the problem, the host receiver board may be a problem (but the general host receiver board Problem less), if sometimes far and near, may be the impact of the surrounding environment, refer to the next question.

Wireless remote control remote distance sometimes sometimes far away

Wireless remote control distance sometimes sometimes near, there may be interference for the surrounding environment of electromagnetic waves, if located in the radio station, near the TV station, or BB machine launch pad, mobile phone relay station, radar station or other launch station near the electromagnetic interference , The distance is very normal, there are some industrial equipment such as high frequency plastic press can also produce a great deal of interference, if in these neighborhoods, will also cause the distance, if the exclusion of these interference, check the receiving antenna contact is good?

After replacing the battery, the wireless remote control does not respond

Replace the battery, the remote control no response, please check the battery polarity with or without reverse? Is the battery sheet in good contact? If the contact is good, the remote control LED should be bright, if the LED light, and the host no response, there may be remote control chip damage, because this chip is static sensitive devices, especially in the north, hand touch the circuit board easily damaged. After the damage can only replace the chip.
