ICP Control Board Mounting Plate for SUP23E230V2IA — OEM B03529 | Ships Today

Overview

The B03529 is a genuine OEM control board mounting plate for the ICP / Tempstar / Heil SUP23E230V2IA. This plate provides the rigid, properly grounded platform that the unit's control board fastens to, holding it in position away from sheet-metal edges and moving components while maintaining clean wire routing. A corroded, cracked, or missing plate can let the board flex, short against the cabinet, or trap moisture — leading to intermittent faults and nuisance lockouts. Installing the correct OEM plate restores secure board mounting and proper chassis grounding.
