6.1.6. How to remove the heater 

The process: Remove the shelves→Remove the control panel film→Remove the screws→

Remove the display supporter  →Remove the middle electrical box→  Remove the screws

→Remove  the  upper  and  lower  air-duct  board.→  Remove  the  inner  air-duct  board→

Remove the heater fixing screws→  Remove the heater 

 

After removing the air-duct board, the heater is on the back of it, remove the fixing screws and 

we can remove the heater.(Fig.10)
