Electrolux Short Cycling / Control Instability

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 unit for room, Thermostat sensor too close to supply air, Dirty filters causing icing, Low refrigerant charge, Faulty control board

Safety: Turn off power before moving sensors.

Steps:

Check sensor location: Ensure the room temperature sensor is in the return air stream, not directly in the cold supply air.
Clean filters and coils: Dirty components can cause icing and short cycling.
Check setpoint: Avoid setting the temperature extremely low; set around 23–25°C for normal cooling.
Observe cycle time: If the unit cycles every few minutes even under moderate load, a technician should check refrigerant charge and control logic.
