Hi

 

Ok thanks for that.

 

If the cooling fan is running all the time then the thermostat for the cooling fan is faulty.

 

Remove the back panel and there look at the wires to the grill element at the top.

To the right of the grill element you will see a small square thermostat with 2 wires on it.

 

This is the cooling fan thermostat and you will need to replace this and that will cure the fault here.

 

If you need anymore info just get back to me.

Hi

 

Ok very strange as looking at the wiring diagram and from what I remember on this model the cooling fan has a direct neutral from the mains connection.

And the live run through that thermostat at the back. So when it gets hot the thermostat cuts in and give the cooling a live for it to run and when the thermostat cools down it cuts out so stops the live and the fan running.

 

Test that thermostat with a multimeter. As its a cut in thermostat it should give a open circuit reading. If its giving a closed circuit reading then its either the wrong thermostat or its faulty.

 

Let me know what reading you get from it.

 

Regards
