Product review (5 stars): Danby DFF501WDD02 All Refrigerator
My Danby all refrigerator (DFF501WDD02) kept freezing up and blowing warm air.  After talking to a repairman, he suggested I order online and replace myself.  His time and the part would've been nearly $200.  I appreciated his honesty and began my search.  We found the part online but it was cheaper on Amazon.  I ordered and it arrived quickly thanks to Prime.  After pulling the fridge from the wall it took a few minutes for my husband and I to finally locate where to remove the old timer.  On this model it was on the very bottom left-hand corner hidden behind a bracket.  The old slipped out and the new plugged right in seemlessly.  We can now use our garage refrigerator again without having to empty and manually thaw it every few days.  This refrigerator also runs really cold.  Manufacturer suggestion is to keep the temperature at 4, but I turned it to 2-3 and it's still ice cold.
This is a 12-hour timer.
