I'm a newbie, just trying to troubleshoot an old Amana BRF20 from 1999. No problems with it (aside from some vegetable freezing) until now when, during a heatwave, the freezer just won't freeze anymore. I've followed the flowchart and am worried I'm headed to "sealed system failure." Yes, the condenser coils were filthy. I've vacuumed them, though I'll need a real deal brush to get them truly clean. Yes, the cooling fan for the coils is working. (I rolled the unit out, took of the back, and cleaned from there, so I've seen it in action.) Yes, the evaporator fan is running. (At least I can feel the cold [perhaps I should say "cool"] air flowing.) I don't seem able to attach photos, so let me describe the evaporator. When I first took off the freezer back to view it, it had a small amount of ice relatively evenly across the tops of the fins. I unplugged the unit when doing my cleaning. It's been on again for at least 40 minutes, and the evaporator has no ice at all. Indeed, it has drops of water dripping down it. I'm doomed, aren't I?
Thanks for any advice. I can take temperatures, if that would help. I do note that there's what seems to me a really stupid design for the condenser coil housing. They rest on what feels like sheet of flocked paper that completely covers their lower sides, nearly touching them. Seems like that would act as an enormous dust layer. Ought I take it out? It feels as if I could do so pretty easily. Was this installation lameness? Or does it serve a purpose I can't fathom. Or does it just not matter because my fridge is toast?
