I have a Trane XE90 Model Number TUX060C936C3 that seems to be working, there is warm air blowing, but it will only run for a few minutes then turn off. It is very cold in Colorado right now (about 5 degrees) and I have the thermostat set to 75 degrees just to test the system. I also noticed a little pool of water at the bottom of the unit, but being a novice I don't know whether or not that is acceptable. I cannot find ANYTHING on the Trane website for this model ANY assistance would be helpful. I noticed that the L.E.D. is blinking continuously. Any suggestions??
