Parts list for the 3400-815 Coleman electric furnaces. 14.4KW or 49,000 BTU.

Unlike many newer Coleman furnaces, the Coleman 3400 series was not built to be air-conditioner ready. To make the furnace A/C ready, an A/C control box and upgraded blower assembly were usually added. If this furnace was paired with an air conditioner of a different brand, the A/C control box and blower assembly may be of that brand. For example, adding a Nordyne air condition was common practice.
