The housing pan may define an internal bottom surface. The PCB may be held within the housing pan above the internal bottom surface. The spacer frame may include a skeletal platform extending beneath the PCB in support thereof. The TCIP may be held on the spacer frame between PCB and the housing pan. ## Claims ### Claim 1 An appliance board housing comprising: a housing pan defining an internal bottom surface; a printed circuit board (PCB) held within the housing pan above the internal bottom surface; a spacer frame comprising a skeletal platform extending beneath the PCB in support thereof; and a thermally conductive insulator pad (TCIP) held on the spacer frame between PCB and the housing pan, wherein the internal bottom surface comprises a raised ridge aligned with the TCIP. ### Claim 2 (depends on 1) The appliance board housing of claim 1, wherein the spacer frame defines a frame hole vertically aligned with an electronic component of the PCB. ### Claim 3 (depends on 2) The appliance board housing of claim 2, wherein the skeletal platform comprises a plurality of frame arms extending parallel to the PCB, and wherein the frame hole is one hole of a plurality of holes defined by the plurality of frame arms. ### Claim 4 (depends on 3) The appliance board housing of claim 3, wherein the PCB comprises a plurality of electronic components held within the plurality of holes. ### Claim 5 (depends on 1) The appliance board housing of claim 1, wherein the raised ridge is held in static contact with the TCIP to draw heat therefrom. ### Claim 6 (depends on 1) The appliance board housing of claim 1, wherein the spacer frame further comprises a plurality of friction tabs extending away from the housing pan and holding the PCB to the skeletal platform. ### Claim 7 (depends on 1) The appliance board housing of claim 1, wherein the spacer frame comprises a retention door selectively clasped to the skeletal platform. ### Claim 8 (depends on 7) The appliance board housing of claim 7, wherein the retention door is held over the TCIP. ### Claim 9 (depends on 7) The appliance board housing of claim 7, further comprising a living hinge pivotally joining the retention door to the skeletal platform. ### Claim 10 A domestic appliance comprising: a cabinet defining a vertical direction; and a board housing movably attached to the cabinet, the board housing comprising a housing pan defining an internal bottom surface, a printed circuit board (PCB) held within the housing pan above the internal bottom surface along the vertical direction, a spacer frame comprising a skeletal platform extending beneath the PCB in support thereof, the spacer frame further comprising a retention door selectively clasped to the skeletal platform, and a thermally conductive insulator pad (TCIP) held on the spacer frame between PCB and the housing pan. ### Claim 11 (depends on 10) The domestic appliance of claim 10, wherein the spacer frame defines a frame hole vertically aligned with an electronic component of the PCB. ### Claim 12 (depends on 11) The domestic appliance of claim 11, wherein the skeletal platform comprises a plurality of frame arms extending parallel to the PCB, and wherein the frame hole is one hole of a plurality of holes defined by the plurality of frame arms. ### Claim 13 (depends on 12) The domestic appliance of claim 12, wherein the PCB comprises a plurality of electronic components held within the plurality of holes. ### Claim 14 (depends on 10) The domestic appliance of claim 10, wherein the internal bottom surface comprises a raised ridge aligned with the TCIP. ### Claim 15 (depends on 14) The domestic appliance of claim 14, wherein the raised ridge is held in static contact with the TCIP to draw heat therefrom. ### Claim 16 (depends on 10) The domestic appliance of claim 10, wherein the spacer frame further comprises a plurality of friction tabs extending away from the housing pan and holding the PCB to the skeletal platform. ### Claim 17 (depends on 10) The domestic appliance of claim 10, wherein the retention door is held over the TCIP. ### Claim 18 (depends on 10) The domestic appliance of claim 10, further comprising a living hinge pivotally joining the retention door to the skeletal platform. ### Claim 19 An appliance board housing comprising: a housing pan defining an internal bottom surface; a printed circuit board (PCB) held within the housing pan above the internal bottom surface; a spacer frame comprising a skeletal platform extending beneath the PCB in support thereof, the spacer frame further comprising a retention door selectively clasped to the skeletal platform and a living hinge pivotally joining the retention door to the skeletal platform; and a thermally conductive insulator pad (TCIP) held on the spacer frame between PCB and the housing pan; wherein the spacer frame comprises a retention door selectively clasped to the skeletal platform. ### Claim 20 (depends on 19) The appliance board housing of claim 19, wherein the retention door is held over the TCIP.
