    Diagnose problem of trane furnace xl80
    My furnace was in 2ft. Of water for about 24 hours. I replaced the blower motor and start capacitor because it shorted out. The blower will still not start. The 120v/24v AC transformer and the 5 amp fuse in the blower compartment check okay. Should I assume that the circuit board is bad and needs to be replaced?
    Thanks Pat

    Probably! Try using a hair dryer on the board for a while. It may dry some of the components that are still damp... Is the auto ignition function working?
