3500-818 Coleman Electric Furnace Parts
Parts list for the 3500-818 Coleman electric furnaces. 16.1KW or 55,000 BTU.
The 3500 and 3500A series electric furnaces are mostly identical. Unlike many newer Coleman furnaces, the Coleman 3500 series was not built to be air-conditioner ready. To make the furnace a/c ready, the blower assembly was upgraded to a 3500-6901/A and an a/c control box was added. For 2-wire thermostats, a 3500-5821 a/c control box was added. For 4-wire thermostats, a 3500-5841/B a/c box was added. For heat pumps, a 3500-5871 control box was used. For 4-5 ton air conditioners, a 3500-7901 blower assembly was used. The original 3500-5901 blower assembly is no longer available. 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.
