Solution
Please inspect whether power supply is normal.
Power on after the power supply is normal.
Wait for the temperature of ceramic plate return
to normal.
Touch "ON/OFF" button to restart unit.
Wait for the temperature of IGBT return to
normal.
Touch "ON/OFF" 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.
