Why does my KTC COMPACK 2 Air Compressor motor thermal sensor cause the machine to stop?
- EElizabeth MartinAug 14, 2025
If the motor thermal sensor causes your KTC Air Compressor to stop and indicates the main motor is overloaded, ensure the electric power supply is correct and that the 3 power phases are at approximately the same value with cables firmly secured. Also, check for damaged cables and ensure the main motor ventilation is free of obstructions. If the motor is running in two phases, have it checked by a qualified technician. The oil separator differential pressure may be above 1.0 bar, causing high system absorption; have the unit checked by qualified personnel. High environmental temperature can also be a factor, so ensure the room is well-ventilated. To restart, reset the machine using the button on the control panel.
