Just installed an condenser unit toa amana air command furance model #guc-c this unit never had a/c installed.outside unit and ran new 18/5 t-stat wire and a new lux t-stat model# dmh110. The furance will run the blower will kick on run.the out side unit will kick on and run but the blower will not come on. The blower will not come on even if you switch t-stat over to fan on position. Even switched t-stat and still won't work. Furnace control board is a white rodgers.

Will fan run in heat mode? Sounds like need to go back and look at tstat wiring
