HVAC Furnace Control Board

This item is an electronic control board assembly typically found inside a residential heating, ventilation, and air conditioning (HVAC) furnace system. The green printed circuit board (PCB) is mounted to a sheet metal backing plate and densely populated with various surface-mount and through-hole electronic components, including resistors, capacitors, and an integrated circuit. A prominent screw terminal block is situated at the top edge of the board with labeled connections for R, W, Y, G, C, and other low-voltage thermostat wiring. Numerous multi-colored stranded electrical wires—including red, blue, yellow, white, brown, and black insulated conductors—are connected via plastic multi-pin plug-in connectors and slide-on terminals, weaving across and obscuring portions of the circuit board. A black component near the bottom features a white data matrix barcode sticker with printed alphanumeric text reading 'CNT07541' and related manufacturing codes. The assembly shows minor dust accumulation consistent with normal operation inside an enclosed HVAC service compartment, but no overt physical damage, scorching, or component failure is immediately apparent from visual inspection. The identification of this component as a generic HVAC furnace control board rests entirely on the visual layout featuring standard thermostat screw terminals, multi-wire harness connectors, and electronic relay components typical of modern residential furnace control systems.

Based on what I can see in the photograph, this item appears to be a generic HVAC furnace control board assembly, potentially bearing a manufacturing barcode reading 'CNT07541'. I cannot verify the exact functional working condition, internal electronic integrity, or exact OEM part specifications from a photo alone, as a physical inspection and bench testing would be needed to confirm whether the circuitry is fully operational. The estimated value range of $100 to $200 reflects typical secondary market pricing for replacement residential HVAC control boards of this general type, assuming the component is functional. General market demand for heating and cooling repair parts is steady among technicians and DIY repairers seeking specific replacement modules, though values fluctuate based on exact compatibility and brand matching. If this unit turns out to be an unbranded aftermarket replica, a non-working surplus item, or incorrectly identified, the market value would likely drop significantly to a nominal salvage price. Confirmation of proper working order and exact part matching would require in-person electrical testing and cross-referencing against manufacturer documentation.
