      If your Ameristar Air Conditioner doesn't start, it might be due to the overload protection switch delaying the start for three minutes, or the unit might be in standby for one minute. If a malfunction is detected, immediately turn off the main power switch.

    Why does the indoor unit of my Ameristar Air Conditioner still run after I switch it off?

      Kenneth ReyesAug 20, 2025
      If the indoor unit of your Ameristar Air Conditioner continues to run after being switched off, it's because the fan motor runs for 20-70 seconds to use excess cooling and heating and prepare for the next operation. If a malfunction is detected, immediately turn off the main power switch.
