    Trane air handler blower fan won't shut off.
    Unit was working great till, my wife messed with thermostat controls while I was away for the week.. since then blower fan won't quite running.. I have reset all factory settings on thermostat,neither in heat or ac mode will blower shut off,it won't shut off when I put it in fan on or auto, the ac kicks on & outside unit runs to temp. but blower won't shut off, I then went to thermostat a trane tcon401 & completely disconnected from base & blower styill runs in air handler,handler unit is a trane,twh030b1401a.. I opened up blower door & fan kept running,I shut off at breaker next to unit ,it didn't appear that contacts were bad,any help would be great.. hate to pay that service call if its an easy fix.
