Why Cooper & Hunter SOPHIA CH-09MSPHMC-230VI Air Conditioner does not turn on?
- JJesse WellsAug 6, 2025
Your Cooper & Hunter Air Conditioner might not be turning on due to a few reasons. Firstly, there's a 3-minute protection feature to prevent overloading, so the unit can't be restarted within three minutes of being turned off; wait three minutes before trying again. Secondly, if the Operation light and PRE-DEF indicators are lit (for Cooling and Heating Models), or the “Fan Only” indicator is lit (in Cooling-only Models), the outdoor temperature might be too cold, activating the unit’s anti-cold wind or anti-freeze protection to defrost; in this case, wait until the outdoor temperature rises.
