This is a direct replacement for the Coleman 7975-3881 part, so it should fit and function exactly like the original. The 3-inch sensing distance is standard for these units and provides reliable flame detection to keep your furnace running safely. The metal body construction is durable and built to handle the heat cycles that furnace components go through. Installation is pretty straightforward if you're comfortable with basic HVAC repair - just make sure to turn off power to the furnace first for safety. The wall-mount design makes it easy to position correctly, and the electrical connections are typically simple screw terminals. I've seen these solve so many furnace issues where the unit would try to start but then shut down because it couldn't detect the flame properly. The quality seems solid - it's not some cheap knockoff that'll fail in a few months. Whether you're a homeowner doing your own repairs or an HVAC technician looking for reliable parts, this sensor delivers the performance you need to get your furnace running reliably again. Definitely one of those parts where using a proper replacement rather than trying to clean an old sensor can save you from repeated service calls.
