The  air  conditioner

does  not  react  after 

it  is  powered  (  after 

the plug is inserted, 

the  buzzer  does

not sound and the 

remote  startup  has

no  response)

The remote controller

does  not  receive 

signals  (after  it  is

powered,  the  buzzer

will  sound,  unless  it

has  malfunction)

  The circuit or the part of the air conditioner has

  malfunction. They heat and break the insulation
