I cannot stand this.
Ice and snow are no favorites of mine. No matter if it is caused by the weather, it is food or in a freezer.
This freezer had this problem from day one. It needs to be cleaned every 3-4 days. I think the thermostat is broke. The only reason it is still there is that we only use it for a few months a year. Soon it will, not be needed anymore. Our house and outside will be the fridge. After the dishwasher this is the worst buy ever.
It is defrosting now.
Door open, electricity switched off and some big towels to absorb the water. I will have a look in two or three hours time.
Years ago I bought a fridge that cleaned itself. It never did and no matter what they said it was smelly at times. Fridges and freezers are the dirtiest engines we use in our house. If you think no bacteria live inside or the door's rubber you are wrong. Never accept a dirty, second-hand fridge. It is a danger to your health.
