My beer fridge is not entirely behaving itself. It is a small frost-free larder one, and had a new thermostat fitted earlier this summer.
The problem is that the cooling plate is gradually icing up from the bottom. Periodically, I have to shut it off, leave the door open, and allow the plate to warm sufficiently for me to knock the accumulated frost off with a blunt instrument. It does not seem to matter how low I set the stat, but the higher the setting, the worse the icing. I believe the stat is running the frost-free cycle, but there is no control for this. The stat probe is mounted fairly high on the plate, above all the icing, but I doubt if I could move it to make any difference. The door seal appears to be sound and I try to keep the fridge fairly well stocked (ahem).
Any clues ? I suspect I am just stuck with it until such time as I figure another browse through the small ads is worthwhile (it was 2nd hand). Still, it'd satisfy my curiosity to know what the cause of problem is, even if there is nothing I can do about it.
TIA
