I have a Trane XE90 furnace with A/C. The other day the blower just suddenly stopped but the A/C continued to work. On the thermostat I switched to just Fan but still nothing. When I switched to just Heat, the gas ignited but the blower still had no power. I looked at the circuit board and a little red LED light blinks about every second. It seems like the motor is not getting any power. Does anyone know if the problem is either one of the following:
1) Bad circuit board. Is the blinking light on a Trane XE 90 mean that the board is fine?
2) Bad capacitator. How do I check to see if it is still good?
3) Motor is shot. There was no overheated smell when I checked it to see why the blower sunddenly quit. I spun the blower and it spins freely so it is not seized. Could it be a ground wire or any other wire? How do I check to see if power is going to the motor?
4)Thermostat. Could it be the mechanism that controls the fan is shot? Or is that not possible?
Your suggestions, if you know or if you've ever experinenced this, would be a great help.
Thanks.
