Common faults and troubleshooting methods of garage door wireless remote control:

Wireless Keypad Manufacturers china

1. When the Wireless Keypad is pressed, the indicator light of the garage door remote control is not bright, or the indicator light of the remote control is very dark:

The battery of the remote control is dead or low. After replacing the battery (pay attention to the positive and negative polarity), if the indicator light is still off, check whether the buttons are damaged or oxidized (if some buttons respond, some are not, It is very likely that the keys are damaged, or the diode on the circuit is damaged), if it doesn't work, it may be that the remote control is damaged.

2. When the Wireless Keypad is pressed, the host does not respond

First check whether the Wireless Keypad is the original remote control. If there are two Wireless Keypads, check that one of the remote controls responds, and the other one does not respond. Maybe the remote control password is lost. Press the learning button and the LED light flashes. Press the same button of the remote control twice. If the LED light flashes quickly, it means the learning is successful. If the LED light continues to flash slowly, it means the learning is unsuccessful. There may be a problem with the main control board. If repeated learning is unsuccessful, the remote control may be damaged; if any remote control cannot be controlled and the learning is unsuccessful, there may be a problem with the receiving board. Check the sensitivity of the receiving board and other related circuits. .

3. When the garage door is running, it cannot be stopped by pressing the Wireless Keypad of the garage door or the distance to stop by remote control is very close.

The garage door cannot be stopped when it is running. The main reason is that a large number of strong electromagnetic waves are generated when the motor is running, which interferes with the power supply of the receiving circuit, and generates a large amount of clutter on the power supply, which makes the remote control distance very close. The following can be used Solution:

1. Add magnetic beads, magnetic rings, inductors and other devices to the power and ground of the receiving circuit and the main control circuit, and add more filter components such as filter capacitors.
2. If the receiving circuit and the main control circuit can be shielded, it will have a better effect.
3. The installation position of the receiving board and the main control board should be as far away as possible from the motor.
4. Install filtering and pulse components on the two poles of the motor, and try to shield the motor.
5. Pull out the receiving antenna with a shielded wire and place it a little farther away from the motor, which is beneficial to increase the remote control distance.

The above measures can help increase the stopping distance of the Wireless Keypad remote control, but in general, the stopping remote control distance is shorter than the starting remote control distance.
