Why is my Hiyasu Air Conditioner cooling/heating poorly?
If your Hiyasu Air Conditioner isn't cooling or heating effectively, consider the following: Is your temperature setting appropriate? Check if the air inlet or outlet is blocked. A dirty filter can also cause this issue. Ensure that windows and doors are closed, and that a low fan speed isn't set. Also, check for any heat sources in the room.
What to do if my Hiyasu Air Conditioner unit can not be started up?
If your Hiyasu Air Conditioner unit won't start, check these items: Is the power cut off? Ensure the power plug is securely in place. Check if the circuit protection device has tripped. Have professionals test if the voltage is too high or too low. Verify that the TIMER is correctly set.
How to fix a Hiyasu Air Conditioner remote controller that is not working?
If your Hiyasu Air Conditioner remote isn't working, first, check for any magnetic or electrical interference nearby; if there is interference, unplug the unit and plug it back in. Ensure the remote is within its operating range and nothing is blocking the signal. Also, check the batteries and replace them if needed. Finally, check the remote controller for damage.
What to do if my Hiyasu Air Conditioner indoor unit is leaking water?
If your Hiyasu Air Conditioner indoor unit is leaking water, the humidity might be high. Also, check if the condensate is overflowing or if the drain hose is loose.
Why is my Hiyasu Air Conditioner indoor unit making noise?
The noise from your Hiyasu Air Conditioner indoor unit could be due to the fan or compressor relay switching on or off. Also, a sound of refrigerant flowing in reverse may occur when defrosting starts or stops.
Why is my Hiyasu Air Conditioner indoor unit not blowing air?
If your Hiyasu Air Conditioner's indoor unit isn't blowing air, especially in HEAT mode, it could be preventing cold air from blowing until the indoor heat exchanger warms up (this usually takes less than 2 minutes). Also, in HEAT mode, if it's very cold or humid outside, frost might form on the outdoor heat exchanger, causing the unit to defrost automatically, stopping airflow for 3-12 minutes. During defrosting, water or vapor may be emitted. In DRY mode, the fan might stop for 3-12 minutes to prevent condensation from re-vaporizing.
Why is my Hiyasu Air Conditioner outdoor unit leaking water?
If your Hiyasu Air Conditioner outdoor unit is leaking water during cooling, condensate may be forming around the pipes and connection joints. During defrosting, thaw water flows out. During heating, water on the heat exchanger may drip out.
Why is there moisture on my Hiyasu Air Conditioner air outlet?
If your Hiyasu Air Conditioner operates in high humidity for a long time, moisture can form on the air outlet grill and drip off.
