Cobra blower/furnace


I have a cobra blower, model # cd5bxa030000aaaa, that has quit blowing. When I turn the ac on the outside unit will come on, but not the inside. The LED on the control board is not on. I checked the 3amp fuse and it was good. I have 120v going to the transformer and 27v coming out going to the control board. What now? Bad control board? Something else I need to check?

Thanks,

Rickey

Check if the board is sending voltage to the blower.

Board was not getting voltage to the blower. By-passed board and the blower came on. I replaced the board, all is good now.

Thanks
