I wonder if I have a control board and transformer issue. While the blower controls and blower work as intended, the lights are another story. When pressing either light on/off button, I hear the normal "beep", yet no lights. When I disconnect the leads between the circuit board and the transformer, I see 110VAC leaving the board. When reconnecting the leads between the board and the transformer, I see no 110VAC leaving the board nor 12v leaving the transformer. Could I have a bad relay switch in the board and/or bad transformers (2 in this model)? Also, assuming both, what is the availability of a new board and a duo transformer kit? The current transformers are heard-wired with the harnesses and quick disconnects between the board and the 4 lights attached.
