- Due to clogged gas pipes: Improper cleanliness during gas pipe installation can cause blockages due to the accumulation of impurities. Additionally, the small size of the external gas pipe near the condenser can easily lead to frost formation on the evaporator coil.

- Due to gas shortage: Insufficient gas levels reduce the efficiency of the machine. In such cases, cold air may not be released, causing the evaporator coil to freeze.

- If the cooling fan blades are damaged: During transportation, the cooling fan blades may break or deform. This can easily lead to uneven heat dissipation, resulting in frost formation on the evaporator coil.

From the above causes, we can explore some remedies for the H99 error as follows:

- In low ambient temperatures, users should increase the air conditioner temperature setting. However, it is advisable to refrain from using the machine during such periods.

- If the gas pipe is clogged, you need to protect the condenser unit. Regular maintenance is essential to detect and promptly address any gas pipe obstructions.

- If the H99 error is due to low refrigerant, you can contact the air conditioner maintenance service to recharge the gas. Before refilling the gas, check for any gas leaks in the pipes to avoid wastage. Make sure to inspect the gas pipes for potential leaks before adding more gas to prevent depletion.
