Trane air handler blower works fine in manual mode with heat/cool setting off. When switched to cool position, compressor comes on but blower turns off.

  • Can you post the wiring diagram for your air handler please? – ThreePhaseEel Jun 19 at 23:40
  • Can you give us the model # and verify your LED’s are not flashing. Some models make sure the coils are cold before starting the air handler it usually only takes a couple of minutes. – Ed Beal Jun 20 at 15:43
