Looked at this fridge today: Complaint was frost build up. It had Frost built up in the freezer about 3-4 inches top, bottom, and back. Door gaskets are good. Defrosted unit and keeps cold great. I looked at parts diagram and see there is a small evaporator heater but can't find any control for defrost. Am I actually looking at a manual defrost unit? There is also a "defrost scraper" on the parts diagram I did find when I defrosted it.
I never see manual defrost fridge and freezers so am confused if that is what I'm looking at.
Thanks for any advice.
