What to do if my Giatsu ADMIRA GIA-CF-18ADMR32 Air Handlers unit does not turn on?
- RRoberto HicksAug 3, 2025
If your Giatsu Air Handler does not turn on when you press the ON/OFF button, it might be due to a few reasons. Firstly, the unit has a 3-minute protection feature to prevent overloading, so you must wait three minutes after turning it off before restarting. Secondly, on cooling and heating models, if the Operation light and PRE-DEF indicators are lit, the outdoor temperature is too cold, and the unit’s anti-cold wind feature is activated to defrost it. Lastly, on cooling-only models, if the “Fan Only” indicator is lit, the outdoor temperature is too cold, activating the anti-freeze protection to defrost the unit.
