Why my Carrier Air Conditioner will not start?
- J
  Jeremiah TorresAug 13, 2025
  Your Carrier Air Conditioner might not start due to several reasons: - The main supply switch could be OFF. In this case, switch it to the ON position. - The fuses or main switch might be blown. If so, replace the fuses. - The protection against frequent compressor cycling might be ON. If this is the case, wait for 3 minutes. - The selected temperature might be higher than the room temperature in cooling mode (or lower in heating mode). Adjust the selected temperature accordingly.
