Re: Diplomat APM6855-1
The Diplomat is better.
Empty the fridge and freezer, turn it off and leave the doors open for 48 hours / 2 Days.
When you turn it back on after 4 to 6 hours it will work ok again.
If the problem returns after 6 to 8 weeks it will need a new defrost sensor.
If it does not work ok after the 4 to 6 hours the fan will be the fault.
It is well worth trying to keep the Diplomat if you are looking to replace it I would go for a GORENJE.
