Troubleshooting
Have a multimeter to check voltage and continuity. Use caution when checking high voltage terminals.
Symptom
Possible Solution(s)
The opener does not
run.
1. Check the input voltage of the control board. It should be local AC
electricity.
2. Check the fuse in the control board. Replace the fuse if it was burnt out.
3. Ensure the remote control has been programmed to the control board
before operating.
4. The thermal protector is working because the high temperature after long
working time. Please wait for 20 minutes to let the motor become cold.
5. Check the installing position of the limit magnets. The opener would not
run if both of the limit switches are activated by one magnet.
6. Check the limit switch. Remove the wire connection of the limit switch
which is connected to the 8#, 9#, and 10# terminals of the control board and
then use a jumper wire to short the 3 terminals together to try it again.
Replace the limit switch if the motor could run in both directions.
7. Check the control board. Replace the control board as necessary.
Remote control does
not work.
1. The indicator light of remote control is not on. Check the battery in your
remote control. Replace the battery as necessary.
2. The distance you use the remote is too far away from the opener. Try it
again closer.
3. Remote control is not suitable for receiver. After making sure the codes are
correct, erase remote controls and then re-program the codes in the device.
4. Check the control board. Replace the control board as necessary.
The gate starts but it
is immediately stop or
reverse
1. Check the wire connection of hall sensor board with the main control
board.
2. The opening force or closing force is adjusted too small. Turn the
Potentiometer A to increase the force.
2. Disconnect the gate from the gate opener and check that the gate slides
freely without any binding.
3. Check the control board. Replace the control board as necessary.
The gate opens, but
stops and will not
return.
1. Check the installing position of the magnets. The opener would not run if
both of the limit switches are activated by one magnet.
2. Check the limit switch. Remove the wire connection of the limit switch
which is connected to the 8#, 9#, and 10# terminals of the control board and
then use a jumper wire to short the 3 terminals together to try it again.
Replace the limit switch if the motor could run in both directions.
3. Check the control board. Replace the control board as necessary.
The gate can open,
but fails to close.
1. Photocell is obstructed. Remove obstruction.
2. Check the limit switch. Remove the wire connection of the limit switch
which is connected to the 8#, 9#, and 10# terminals of the control board and
