Why does my Hitachi RAS-4HVNC1 Air Conditioner operation stop?
- J
  James AlvarezAug 14, 2025
  The Hitachi Air Conditioner might stop operating due to several reasons: * The micro-computer may be activated to protect the device from electromagnetic waves. In this case, restart the operation. * If “Motion Sensor ON” is enabled on the wired controller, the unit might stop if the sensor detects absence for a prolonged period, especially if set to “If absent: OFF”. This will stop all indoor units connected to the same wired controller. * Following a power failure, the unit should restart automatically if the failure lasts less than 2 seconds. Otherwise, manually restart the operation.

What to do if my Hitachi RAS-4HVNC1 Air Conditioner has an odor?
- S
  Sherry KhanAug 21, 2025
  If you notice an odor coming from your Hitachi Air Conditioner, it might be due to smells like cigarette smoke or other room odors that have been absorbed inside the unit. To resolve this: * Ventilate the room well while running the unit in fan mode. * Clean the air filter, air outlet, and air inlet grille.

Why is there mist coming from my Hitachi Air Conditioner indoor unit?
- A
  Antonio SotoAug 26, 2025
  Mist coming from your Hitachi Air Conditioner's indoor unit can occur for several reasons: * **In restaurants or kitchens:** Oil attached to the fins might decrease heat exchange efficiency. * **During dry operation:** The air outlet temperature might become too low; try changing the operation mode. * **During cooling operation in humid environments:** The air outlet temperature might be too low; raise the set temperature and the air flow volume. * **During FrostWash:** Frost may form on the fins of the heat exchanger.

Why is my Hitachi RAS-4HVNC1 making sounds?
- C
  Connie BrownAug 28, 2025
  Your Hitachi Air Conditioner may produce various sounds during operation: 1. A grate sound when starting or stopping is normal; it's due to components rubbing as resin parts expand and contract with temperature changes. 2. The sound of water flowing or burbling during operation is the refrigerant flowing or the drain-up mechanism draining water, especially noticeable when starting or stopping the compressor (for about 3 minutes). 3. A growling sound may occur temporarily after changing the air flow volume because the fan motor makes a temporary sound when the fan speed changes. 4. Crackling sounds or the sound of frost melting during FrostWash are normal, caused by the heat exchanger fins freezing and thawing and the extension and contraction of resin parts due to temperature changes.

Why is there dew condensation on my Hitachi RAS-4HVNC1 Air Conditioner indoor unit?
- J
  johnstonlisaSep 2, 2025
  Dew condensation on your Hitachi Air Conditioner's indoor unit can occur due to: * Operating the unit in a humid place (relative humidity around 80%) for an extended period. * During or after FrostWash, especially in humid (around 80% relative humidity) and high-temperature environments (above 30°C).

Why is there white smoke from my Hitachi Air Conditioner indoor unit?
- M
  Marie WheelerSep 9, 2025
  White smoke from the Hitachi Air Conditioner's indoor unit may occur at the beginning of the heating season. This can happen when dust attached to the heat exchanger dries out.
