My Midea Kool King KWDUK-08CRN1-BCL0 air conditioner used to cycle on for 2 minutes and off for 10 minutes, but now it runs without stopping unless I change the temperature. Why is this happening?

If your Midea Kool King KWDUK-08CRN1-BCL0 has stopped cycling and is running continuously, it usually indicates that the unit is struggling to reach the set temperature or the thermostat is misreading the room conditions. Here are the most likely causes and solutions based on the manual:Dirty Air Filter: A clogged filter restricts airflow, making the unit work much harder and longer to cool the room. The manual recommends cleaning the filter every 2 weeks.Temperature Setting: If the set temperature is very low or the outside heat has increased significantly, the unit will run continuously to try and reach that target. Try raising the temperature setting slightly to see if the unit begins to cycle again.Blocked Air Vents: Ensure there are no curtains, furniture, or debris blocking the air inlets or outlets, as this prevents efficient cooling.Room Size or Heat Load: If a door or window is left open, or if there are new heat-generating appliances in the room, the 8,000 BTU capacity may no longer be sufficient to reach the cutoff temperature.Dirty Coils: If the outdoor coils are covered in dirt or debris, the unit cannot dissipate heat effectively, causing it to run without stopping. The manual suggests an annual inspection and cleaning of these coils.If the unit continues to run non-stop even when the room is clearly colder than the set temperature, there may be a fault with the temperature sensor or the control board, in which case you should contact Midea customer support.
