The heat exchanger plays a critically-important role in the safe operation of your furnace. Essentially, this metal component keeps the combustion fumes produced by the furnace's fuel burner contained so they're safely directed up the system's exhaust flue. If the device fails for any reason, those fumes containing toxic gases including carbon monoxide can escape into the warm air being distributed through your home. Here are some common heat exchanger-related issues that can occur.
