I have a coleman furance in my 1991 mobilehome.. Model 7956A856 S# 039067087. I believe it was mfg. March 1990. The outside condenser plate is rusted and unreadable. I am assuming it is a coleman also. But need to know what model was compatible with the furance? It is Dual run capicter for condenser fan motor and compressor. Would appreciate any help on this.
