Makita part 620548-2 — genuine Makita controller board designed to replace the internal electronic control module in select 18 V LXT brushless driver‑drills. It restores the tool’s electronic speed control, forward/reverse switching and the interface to the trigger, LED circuit and battery terminals; supplied as the single controller assembly (part 620548-2).
Fits (examples): Makita XPH12 and the XFD12 series (XFD12R / XFD12T / XFD12Z and XPH12 variants), and the equivalent DHP484 / DDF484 model — confirm your exact model stamping before ordering.
Key details for repair:
- Function: complete electronic controller/PCB that governs motor output, speed regulation and reverse/forward logic.
- Tool family: intended for Makita 18 V LXT 13 mm driver/drill platforms (the 13 mm chuck/drive capacity on these models corresponds to the 1/2" class).
- Package: sold as one replacement controller (ready to install into the original housing and mate with the tool’s existing connectors and components).
If the symptoms are intermittent motor power, loss of speed control, or no forward/reverse response, replacing the 620548-2 controller with this genuine Makita board will return the original electronic control behavior for the listed models.
