Makita 620364-2 Spare Part - CONTROLLER 110V

Genuine Makita 620364-2 — Controller 110V (PCB) for HM1812 breaker hammer

Restore the electrical control functions in your Makita HM1812 with the original Makita 620364-2 controller board. This is the internal electronic control assembly that replaces the tool’s control PCB and LED circuit so the hammer’s soft-start/soft no‑load behavior, power/service LED indicators and motor protection functions operate as intended.

What it does

- Reinstates the HM1812’s electronic functions (soft start / soft no‑load, LED power & service lights, and automatic brush cut‑off/motor protection logic) so the breaker returns to factory operating behavior.

Fitment

- Made for the Makita HM1812 series.

Notes

- This is the internal controller board (electronic module) designed to plug into the HM1812’s existing connectors and mounting points; installation requires opening the housing and basic electrical/mechanical skills. Some listings identify the part for 110 V corded versions — verify your tool’s voltage.

If your HM1812 is showing failing/service LED behavior, inconsistent soft‑start or unexpected motor cutouts, the Makita 620364-2 controller is the direct fit replacement to restore normal operation.
