I’m looking for some advice for my Miele dual compressor fridge-freezer KFN8997SEed, approximately 18 years old.
In recent years, the drain outlet for the freezer defrost water is icing up with increasing frequency, causing ice to build up under the bottom drawer. Each time, I have defrosted the freezer for 24 hours. I have also cleared some debris that had accumulated in the outlet nozzle.
Am I correct in assuming that the increased frequency of the drain icing up is likely due to the compressor having to run for extended periods due to loss of efficiency? I suspect a factor may be that in earlier years, my kids often left the freezer door slightly ajar after fetching an ice cream, not wide wide enough to trigger the door open alarm
