Service and repair guide 

Overview of further components 

Before carrying out any procedure on the parts described below, ensure the following requirements have been met: 

•

 

The appliance has been disconnected from the power supply and protective measures have been taken to ensure 
the power cannot be switched on again. 

•

 

The appliance is cool. 

•

 

The casing of the appliance is removed. 

•

 

The high voltage capacitors are discharged before commencing work. 

•

 

Anti-static precautions have been taken. 

Equipotential bonding connection 

 

The equipotential bonding connection is located at the bottom left corner of the 
rear panel of the oven next to the mains supply cable. 

 

Electromagnetic Compatibility (EMC) Filter 

 

The  EMC  filter  is  located  on  the  base  panel  at  the  rear  of  the  appliance  on  the 
right hand side. 

 

Diode(s) (high voltage)  

 

The high voltage diode is located on top of the cavity behind the magnetron. 

 

Note:  When  replacing  the  high  voltage  diode,  ensure  it  is  installed  in  the  correct 
orientation. 

 

Cavity temperature sensor (thermocouple) 

 

The cavity temperature sensor (thermocouple) provides temperature feedback to 
the  SRB  board  to  control  the  cavity  temperature.  The  cavity  temperature  sensor 
(thermocouple) connects via a black and a red cable to the SRB board and passes 
in to the front left side of the cavity through a thin tube.  

 

Exhaust pipe 

 

The  exhaust  pipe  leads  steam  from  the  cavity  to  the  cooling  duct  and  the  rear 
outlet of the oven. A protective strip prevents touching the outlet when hot.
