Genuine DoorKing 4100-012 control board — the board for DoorKing 6524 and 9024 DC gate operators — units built before January 2016. The 6524 DC swing and 9024 DC slide operators use the 4100 family of boards; the AC 6500 and 9000 use the 4405-010 instead.
The 4100 family has four boards and no dropdown. Unlike DoorKing’s other operator boards, each version is its own part number. Match on BOTH the build date and the motor voltage, reading the number on the board currently fitted:
| Board | Fits |
|---|---|
| 4100-018 | 6524 and 9024 built January 2016 or later — current, with the UL325 monitored-device input |
| 4100-012 | 6524 and 9024 built before January 2016 |
| 4100-019 | 6524 / 9024 with the 24 VDC motor |
| 4100-013 | Pre-UL 6524 / 9024 with the 30 VDC motor |

Is the board actually the problem?
| Symptom | Check first |
|---|---|
| Operator dead, no board lights | The 4001-089 transformer, 1860-073 rectifier and 3500-023 capacitor before the board |
| Runs on mains, dies in a power cut | The two 1801-003 backup batteries |
| Powers up but ignores every input | The board |
| Board lights but the motor will not run | The DC motor (2601-199 on the 9024) and its wiring, then the board |
| Gate opens but will not close | A loop detector or photo eye holding it open, not the board |
| Failed after a storm | Surge damage — the board and the rectifier |
| Burnt smell, scorching or a bulged capacitor on the board | The board — replace it |
After fitting
The new board arrives unprogrammed. Set the limits and force, relearn every remote and transmitter, re-enter timer, loop and accessory settings, and re-test every entrapment protection device before returning the gate to service.
Fit surge protection at the same time. Storm damage is a leading cause of gate operator board failure. If this board died after a storm, the replacement is at the same risk unless the installation is protected.
