Kelvinator Short Cycling / Control or Capacity Issue

Kelvinator split AC indoor unit frequently turns on and off (short cycling).

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Oversized AC for room, thermostat sensor too close to airflow, dirty filter causing coil icing, low refrigerant causing freeze–thaw cycles

Steps:

Clean filters: Dirty filters can cause icing and short cycling; clean them thoroughly.
Check sensor placement: Ensure the room sensor is not directly in the cold air stream; reposition if possible.
Observe coil: If the indoor coil ices up and then melts repeatedly, there may be a refrigerant or airflow issue requiring a technician.
Adjust setpoint: Avoid setting the temperature extremely low; moderate settings can reduce cycling.
