Product review (1 stars): It had absolutely the worse possible condenser ever put on a refrigerator
I have had this fridge for 5 years.  I decided it's about time to clean the condenser coils.  I am a former refrigerator service man.  They're supposed to be cleaned yearly, every 6 months if you have pets.
I pulled off the back panel and was completely dismayed!  It had absolutely the worse possible condenser ever put on a refrigerator!  I didn't even know they made these anymore!
It is a tight coil of tubes covered in aluminum bristles.  Like a bottle brush wound in a coil, then air blows thru it.  It picks up every piece of lint, hair or dust.  There is no good way to clean it.  Vacuuming only takes off the lint on the surface.  I used to condemn to the junk pile every refrigerator I found with this type of condenser, because they were always clogged and have long since hammered the valves out of the compressor rendering the whole unit a piece of junk.
And to top it off when I looked to the left there was not a new style linear-scroll-loaf (whatever they call it) type compressor.  In it's place was an old style reciprocating compressor!  Which are not as energy efficient or dependable as a new style compressor.
Today I will drag an air hose in from the shop and blow out the condenser with 120 psi compressed air.  Then spray the condenser with Awesome Orange cleaner from Odd Lots to eliminate the kitchen grime that makes dirt stick.  Then blow that out with compressed air..  Then I will clean up the huge freakin mess!  Then I will repeat the entire process in my tenants home and in my camper.  YES!  I was stupid enough to buy three of these!  And I can look forward to repeating the process every year!
I don't know if every model Samsung has this cheap condenser.  I saw in a video where LG has them too!
So BEFORE you buy a refrigerator, peek in the vent slots in the back and if you see some coils that look like a bottle brush made from aluminum, about one inch in diameter...just walk away.  Look for one with black smooth condenser.  Sometimes they're flat, sometimes rolled in a coil.  But t least the dirt comes off.  And a long, not round compressor.
Manufacturers sometimes call these SELF-CLEANING simply because there is no way to clean them.
