Why is my Hisense AMW2-18U4RJC Air Conditioner not cooling/heating properly?

  There could be several reasons why your Hisense Air Conditioner isn't cooling or heating effectively. It might be due to a dirty outdoor heat exchanger (like the condenser), heating devices operating indoors, insufficient air tightness from frequent entry/exit, a blocked outdoor heat exchanger, or an incorrect temperature setting. To resolve this, try cleaning the outdoor unit's heat exchanger, removing any indoor heating devices, maintaining better air tightness, clearing any obstructions from the outdoor heat exchanger, and double-checking your temperature settings.

  If your Hisense Air Conditioner won't start, the issue might stem from a power supply failure, a tripped breaker or blown fuse, low power voltage, incorrect remote controller settings, or a dead remote battery. You should inspect the power supply circuit, measure the insulation resistance to check for leakage, and look for defective contacts or current leaks in the power supply. Also, verify and reset the remote controller, and replace the batteries if needed.

  Water leakage from your Hisense Air Conditioner could be caused by a blocked or broken drainage pipe, or an improperly sealed refrigerant pipe joint. Try changing the drainage pipe. Also, re-wrap the refrigerant pipe joint to ensure it is tightly sealed.
