My Conquest 90 was bought in 1995 from Detroit Furnace Co. This furnace was installed in the 48610 area. I have had a problem before, and again this week. When I arrived at this residence the induced draft blower was running, but there was no heat coming out of the vents. There should be a safety switch that would shut off the draft blower , when there is no heat being produced by the furnace. I have the Conquest 90 GLUA model. Your Answer |
