  If your Hisense Air Conditioner isn't starting, several factors could be at play. First, check the power supply circuit to ensure it's functioning correctly. A tripped breaker or blown fuse could also be the culprit. Also, measure the insulation resistance to ground to check for any leakage. Low power voltage can also prevent startup. Verify the remote controller settings and try setting it again, and replace the batteries in the remote controller.

  If your Hisense Air Conditioner is not cooling or heating effectively, start by cleaning the heat exchanger of the outdoor unit, such as the condenser. Ensure there are no heating devices indoors that might be affecting the temperature. Maintain good air tightness indoors by minimizing how often people enter and exit. Check for and remove any obstructions blocking the outdoor heat exchanger. Finally, double-check and reset the temperature to the desired setting.

  If your Hisense Air Conditioner is leaking water, the drainage pipe may be blocked or broken, in this case, change drainage pipe. Alternatively, the wrap of the refrigerant pipe joint might not be completely sealed; re-wrap it tightly.

  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.
