Why won't my LockMaster DKL400UY open or close?
- PparkerwilliamsAug 15, 2025
If your LockMaster Gate Opener isn't opening or closing, there could be several reasons. First, the limit switch wire connector terminal block might be loose, so check the limit switch mode. Second, connecting wires or terminal blocks could be loose; ensure they are properly connected. Third, an electric component on the control board (like Q2, Q91, or Q92) might be damaged, requiring replacement of the component or the entire board. Finally, check that the power switch is turned ON.
