Who is the manufacturer of a Sears brand furnace?

Answer by  kipcat (1964)

Unfortunately Sears contracts its furnaces to different manufacturers based on their bid interval. Most were manufactured by Whirlpool, Heil, and Nordyne, some were manufactured by Janitrol under the Kenmore name. Search the model number at a Sears site.

Most likely it is a Kenmmore or a Carrier. Sears sells both types as well as whirlpool window units. The best way to find out for sure is to contact a Sears repair person and ask them.
