Why does my Grundig Air Conditioner change to fan mode?
- RRachel StanleyAug 8, 2025
Your Grundig Air Conditioner might switch from COOL/HEAT to FAN mode for two reasons: 1. To prevent frost from forming on the unit. Once the temperature rises, it will return to the previous mode. 2. If the set temperature is reached, the compressor turns off. The unit will resume normal operation when the temperature fluctuates again.
