Why Replace Your Heat Exchanger?
A cracked or failed primary heat exchanger can allow harmful combustion byproducts — including carbon monoxide — to enter the living space. Replacing a compromised heat exchanger with a genuine OEM part like the ICP 1193890 restores the safety barrier between the flue gas stream and the supply air, ensuring the system operates as designed.
