on
when
unit
plugged in.
No Auto-Recovery
Problem
No power supply
is
Accessorial power
board and display
board connection
failure
The accessorial
power board is
damaged.
The display
board
is
damaged.
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.
Solution A
Check to see if plug
is secured tightly in
outlet and that
outlet is working.
Check the
connection
Replace the
