Solution
Please inspect whether
power supply is normal.
Power on after the power
supply is normal.
High temperature of
ceramic plate sensor.
Touch power button to
restart unit.
Wait for the temperature
of IGBT return to normal.
Touch power button to
restart unit.
Check whether the fan
runs smoothly; if not,
replace the fan.
Check the connection or
replace the ceramic plate
temperature sensor.
Replace the power board.
