What to do if my Trane Air Conditioner is cooling improperly?
- AAmber WangJul 25, 2025
If your Trane Air Conditioner isn't cooling correctly, it could be due to failed cooling and heating set points on the thermostat. Try power cycling the 'R' input. Another potential cause is an open CC1 or CC2 24 Vac control circuit. In this case, check the CC1 and CC2 coils and the Frostat™ status, as well as the LED indicator in LSD.
