What to do if my intensity IDUFCI12KC-3 does not turn on?

  Shannon CortezAug 10, 2025
  There are several reasons why your Intensity Air Conditioner might not be turning on: * It might be due to the 3-minute protection feature that prevents overloading. In this case, switch off the power supply and wait for three minutes before restarting. * If the Operation light and PRE-DEF indicators are lit (cooling and heating models), the outdoor temperature is too cold, and the unit is defrosting. Allow the unit to defrost and ensure the outdoor temperature is within an acceptable range. * In cooling-only models, if the “Fan Only” indicator is lit, the outdoor temperature is too cold, and the unit’s anti-freeze protection is activated. Allow the unit to defrost and ensure proper outdoor temperature conditions.

Why does my intensity IDUFCI12KC-3 change from COOL to FAN mode?
- S
  Sarah PhillipsAug 14, 2025
  Your Intensity Air Conditioner may switch from COOL to FAN mode for these reasons: * To prevent frost from forming on the unit. The unit will resume cooling once the temperature increases; just wait for the temperature to increase. * The set temperature has been reached, which causes the compressor to turn off. The unit will start operating again when the temperature fluctuates; adjust the set temperature if needed.

What to do if my Intensity Air Conditioner indoor unit emits white mist?

  If you notice white mist coming from the indoor unit of your Intensity Air Conditioner, especially in humid regions, it's likely due to a large temperature difference between the room's air and the conditioned air. This is a normal occurrence, and no action is required.

  Jennifer TaylorAug 26, 2025
  Here are a couple of reasons why your Intensity Air Conditioner's indoor unit might be making noise: * A squeaking sound when the system is OFF or in COOL mode, or when the drain pump (optional) is operating, is normal, so no action is required. * A squeaking sound after running the unit in HEAT mode is due to the expansion and contraction of the unit’s plastic parts. This is also normal, so no action is needed.

What to do if my Intensity Air Conditioner emits white mist from both units?

  Jason HawkinsAug 29, 2025
  If both the indoor and outdoor units of your Intensity Air Conditioner are emitting white mist, it's likely happening because the unit restarted in HEAT mode after defrosting. The mist is due to moisture generated during the defrosting process. This is normal, so no action is needed.

Why does my intensity IDUFCI12KC-3 Air Conditioner make hissing noises from both units?
- G
  Gina RogersSep 3, 2025
  A low hissing sound from both the indoor and outdoor units of your Intensity Air Conditioner may occur during operation due to refrigerant gas flowing through the units. It is also normal when the system starts, has just stopped running, or is defrosting, caused by the refrigerant gas stopping or changing direction. No action is required as this is normal.
