Why does my Bosch Air Conditioner change from COOL/HEAT to FAN mode?
- MMatthew HansenAug 19, 2025
Your Bosch Air Conditioner might switch to FAN mode for two main reasons: to prevent frost from forming on the unit, in which case it will return to the previous mode once the temperature increases. It can also happen when the set temperature has been reached. In this case, the unit turns off the compressor and will continue operating when the temperature fluctuates again.
