Frost-free freezer "modification"

<< < (4/4)

VanMarco:
I rewired all correctly, with good heatsrhink and silicone grease inside, i am now not sure how to manage defrost, itried 30 min, it seemed a bit excessive, right now, it is set at 15 mins 3 times a day, I dunno if i can get away with 2. the first day of test i left no defrost for 24 hours, and i could tell by the fact that it was struggling to cool that it was frosted, once the 30 min defrost ended, it went back to cool as before. Any idea how much defrost i would need?

helius:
It depends on the size and design of the evaporator, but standing fridge-freezers I have seen have been sold with options for defrost every 12 or every 24 hours. The defrost cycle lasts about 10 to 15 minutes and the heater burns about 600 watts.

VanMarco:
The heater is 200 W in that particular freezer

helius:
If you will not be opening it constantly, then a 15 minute defrost every 12 hours should be sufficient. The more humidity that gets let in to the compartment, the faster it will ice up.

VanMarco:
Thanks for all the patience!!
I think when the freezer will be empty again maybe i fit one of these https://www.aliexpress.com/item/1005001387229724.html
this is an exact clone of the eliwell 974
it will probably do a better job at defrosting when needed rather than by a time schedule, but i am a strong believer in if it ain't broken don't fix it
