Yes it is in the area of the Motor at the lower rear of the appliance. I had checked all the obvious things before removing the fridge freezer from its 'built in' Kitchen unit
Thanks for the info. There is no 'click' after the buzz. I guess the owner will have to call a Neff guy after all.
Hi again, there is absolutely no sound of the compressor motor trying to start so I guess it might be a failed or failing relay.
Hi again. Sorry I thought I had mentioned at the start that I had checked the normal things (fuses etc) before removing the complete Fridge/freezer from the Kitchen unit. that is how I identified that the 'buzz was from the rear of the unit in the area of the compressor tank. Buzz is definitely not the normal sound from the motor/compressor running. On looking back at my responses I mentioned removing the fridge from thre unit in my first response to you.
OK, sorry, I missed the removal part.
If it's out, is the compressor hot?
The Tank is only warm
Definitely not a Hum of the compressor running. When it was in place in them Kitchen Cabinet you could hear the type of hum I believe you mean. this is definitelly a Buzz rather like some Door buzzers hence my thoughts that it is a relay problem.
When the buzz occurs I can feel the buzz through the wall of the tank.
