Milwaukee PCBA Housing Kit
Model Number: 31-44-0576
The Milwaukee 31-44-0576 is a genuine OEM PCBA Housing Kit, also listed as the housing assembly, for the 0821-20 M18 High Performance Fan. The PCBA housing is the enclosure that holds and protects the fan's PCBA, the control board that runs the fan's speed settings and power. This kit supplies the housing with its mounting screws, so a cracked, broken, or stripped PCBA housing can be replaced as a unit with the fasteners it needs. Because the housing protects the control electronics and takes the knocks of a portable jobsite fan, a damaged housing can leave the board exposed to dust, debris, and impact or let it shift. Fitting the genuine Milwaukee OEM kit restores the correct enclosure and mounting for the PCBA, where an off-spec housing may not fit the fan or secure the board properly.
This PCBA housing kit is identified as the PCBA Housing Kit, Figure 30, on the Milwaukee service parts list for the 0821-20 M18 High Performance Fan, bulletin 54-49-0890. As a kit it supplies the PCBA housing and its mounting screws, the housing and screws needed to remount the control board. It works with the fan's PCBA assembly (14-20-0647) and the fan's other housing sections, including the AC housing and shroud, which are separate items; this fan runs on both an M18 battery and AC power, so it has both a PCBA housing and an AC box section. Because Milwaukee specifies service parts by serial number as well as catalog number, verify your catalog and serial number against the official Milwaukee service parts diagram before ordering, since running production changes can alter part compatibility within the same catalog number.
