Why DITEC Control Unit door doesn’t open or close?
- TTeresa ReillyAug 5, 2025
If your DITEC Control Unit door isn’t opening or closing, there are several potential causes: * **Power Issues:** Ensure the electrical panel is receiving power by checking if the POWER ALARM LED is steadily lit. * **Short Circuit:** Disconnect all accessories from terminals 0-1 (24 V= must be present) and reconnect them one at a time to identify any short circuits. * **Blown Fuse:** Replace the fuse on the transformer. * **Safety Contacts:** Verify terminals 8 and 9 on the electrical panel, as well as the position of the function selector (if equipped), to ensure safety contacts are properly closed. * **Mechanical Obstruction:** Confirm that the door wings can move freely, as bolts and locks may be obstructing movement.
