IGBT module NTC is integrated inside the module:
 Measure the resistance, it should be between 14-2,8kΩ in a cool machine (in environ-
ment temperature 0-40°C)
 While temperature rises, resistance lowers and at 500Ω point the inverter stops and gives
overheat alert.
 A broken NTC has usually hundreds of kilo ohms resistance, no value at all or short cir-
cuit.
