Key Features
- OEM Electrical Specification — Manufactured to the precise voltage and circuit tolerances required for the DM220's 120V system, ensuring correct output and control response.
- Direct Drop-In Replacement — Engineered to match the original board's connector layout and mounting points, allowing installation without modification to wiring harnesses or housing.
- Confirmed DM220 Fitment — Designed exclusively for the DM220 concrete core drill motor, so compatibility is built in from the start.
- Restored Motor Control Performance — A functioning circuit board keeps the drill motor starting, running, and responding to operator input correctly; a failed board can cause erratic behavior, no-start conditions, or loss of speed control.
- Genuine Husqvarna OEM Quality — Sourced directly from Husqvarna's construction equipment parts program, meeting the same build standard as the original component installed at the factory.
The circuit board assembly is the electronic control center of the DM220 drill motor, managing power delivery and operational functions that keep the unit running safely at 120V. When this board degrades or fails, the drill may refuse to start, lose consistent speed, or behave unpredictably — interrupting core drilling work and putting added stress on connected components. Replacing it with a correct-spec OEM board restores full electrical control and gets the DM220 back to reliable operation.
