Genuine LiftMaster K1D8059-1CC main control board — the board for the VDC generation of LiftMaster’s DC pad-mount operators: the CSL24VDC and RSL12VDC slides and the CSW24VDC and RSW12VDC swings. It sits between the V-generation K1D6597-1CC and the current UL325 K1D8389-1CC.
Three generations, three boards. Read the number on the board in your e-box before ordering — the model name on the cover is not enough. If your board reads K1D8389-1CC you have a U/UL operator; if it reads K1D6597-1CC you have a V-generation unit.

Thinking of upgrading instead? The current K1D8389-1CC is backward compatible with the VDC generation, but it enforces the 2016 UL325 rules and needs monitored entrapment protection on the OPEN side or the gate will not run. For a CSL24VDC or CSW24VDC, LiftMaster’s K1D8389-1CCU kit bundles the board with monitored photo eyes.
Is the board actually the problem?
| Symptom | Check first |
|---|---|
| Gate slows, stops partway, reverses on its own, or dies in a power cut | The batteries. Replace both 29-NP712 at the same time |
| Operator dead, no lights on the board | Transformer, EMI board or bridge rectifier before the board: K204C0211 (CSL/CSW), APOW3 (RSL/RSW), K76-34728, K52C0481 |
| Gate overruns or stops short | The APS encoder, not the board |
| Gate will not reset after an obstruction | The K180A0357 reset switch |
| Loops or accessories not responding | The K1D8080-1CC expansion board, then the loop detector |
| Burnt smell, scorching or a bulged capacitor on this board | This board — replace it |
After fitting
Photograph the harness connections before removing the old board and reconnect the new one the same way. Then set the limits and force, relearn every remote, re-enter timer, loop and accessory settings, and re-test every entrapment protection device to UL325 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.
