      If your Sanyo Air Conditioner isn't working, a protective circuit might have been activated because of lightning. Unplug the unit for at least a minute, then plug it back in. If it starts working, the air conditioner is fine.

    Why the speed of the indoor fan does not change on my Sanyo SAP-KRV91EH?
    • A
      Anthony CopelandAug 20, 2025
      The indoor fan speed on your Sanyo Air Conditioner might not change to prevent cool drafts or because the room has already reached the set temperature. Also, if you press the MODE selector button during operation, it will operate at a very low fan speed (LL) for about 3 minutes before changing to the set speed.

      Mary BeckAug 25, 2025
      If your Sanyo Air Conditioner smells during operation, this might be due to smells absorbed by walls, carpets, furniture, or clothes becoming noticeable. Also, if the air clean filter has been in use for more than 3 months, it may need replacement.

    Why does my Sanyo Air Conditioner make a strange sound?
    • B
      Brooke GonzalezAug 27, 2025
      If your Sanyo Air Conditioner is making strange sounds, it could be the sound of refrigerant gas flowing, which is normal. This can occur when the unit is started, during operation, or after it's stopped. Also, small sounds might be caused by switches or the expansion/contraction of parts inside the unit due to temperature changes, which is also normal.

      The indoor fan of your Sanyo Air Conditioner stops during heating mode when the outdoor unit is defrosting. This is to prevent cool drafts from blowing into the room.
