  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.

Why does my Giatsu ADMIRA GIA-CF-18ADMR32 unit change to FAN mode?

  If your Giatsu Air Handlers unit changes from COOL/HEAT mode to FAN mode, it could be for one of two reasons. It may change its setting to prevent frost from forming on the unit. Alternatively, the set temperature may have been reached, which causes the unit to turn off the compressor.

Why do my Giatsu ADMIRA GIA-CF-18ADMR32 make noises?

  A low hissing sound from both the indoor and outdoor units of your Giatsu Air Handlers during operation is normal. It is caused by refrigerant gas flowing through both units. Also, a low hissing sound when the system starts, has just stopped running, or is defrosting is also normal, because it is caused by the refrigerant gas stopping or changing direction. Squeaking sounds can occur due to normal expansion and contraction of plastic and metal parts caused by temperature changes during operation.

Why is my Giatsu Air Handlers indoor unit making noises?

  Allen JosephAug 16, 2025
  The indoor unit of your Giatsu Air Handlers may make a rushing air sound when the louver resets its position. A squeaking sound might be heard when the system is OFF or in COOL mode, or when the drain pump (optional) is in operation. Also, a squeaking sound may occur after running the unit in HEAT mode due to expansion and contraction of the unit’s plastic parts.
