Why DoorKing 9150 Gate Opener opens but does not close?
- DDon JohnsonJul 27, 2025
If your DoorKing Gate Opener opens but will not close, here are some things to check: * Check the input LEDs. If any are ON, it indicates a problem with a keying device, holding the gate open. * Inspect the secondary safety devices. If any are activated, they will hold the gate open, indicating an issue with the safety device. * Examine the loop detectors. Activation can hold the gate open, suggesting a problem with the loop detector or ground loop. * The operator may be in a “soft shutdown.” Activate any keying device to see if the operator returns to normal operation. * If automatic close is desired, make sure SW 1, switch 2 is ON and set the timer open from 1-23 seconds. * You can also bypass the circuit board and check the motor.
