there is no frost, I can hear a motor but can not see it.
I can not tell. the back of the appliance only shows elec and water pipes
the unit is not cold at all.it failed yesterday. If you are familier with this model,when I press the cold button at the top of the fridge the freezer shows -2 and the fridge 13 cent.it flashes for a while then stops and goes back to 22cent.. the noise from the motor comes from the bottom at the back.
