Samsung Refrigerator

Even at "5 bars", refrigerator compartment won't cool more than 40 degrees below room temperature (can be 85F in August)
- "Power Cool" temporarily lowers temperature more

In wooden kitchen compartment 33 inches wide, 68 inches high, 27 inches deep, with 3 inch space in back
- Hot garage behind back wall - aluminum foil on wall minimizes radiant heat.
- extra open space inside the back refrigerator compartment surrounding round black vent
Refrigerator very quiet - expecting more compressor noise
Draws 3 to 100 watts, monitored with "Kill-a-Watt" digital meter
Freezer compartment works fine at two bars, opened twice per day, often to access "power cool"
Added a 300 cubic/foot per minute floor vent blowing air at lower back left side
- floor vent reduces maximum temperature excursion by 4F, but vent fan is noisy and consumes 40 more watts

Purchased 2019 July 9 for $648 from Home Depot 4401 SW 110th Ave Beaverton OR 97005
delivered 2019 July 22
added 3 year protection plan $90 ... but Home Depot doesn't answer phone within 40 minutes

	Thermocouple temperatures, top is left compartment wall, bottom is interior upper glass shelf
	Inside of compartment. Thermocouple on "stovetop wall", 300 cfm vent at bottom, power routed through Kill-A-Watt meter, foil radiant barrier and 3 inch styrofoam ball spacer in back
	Kill-A-Watt meter feeding power to refrigerator. Can exceed 100 watts during "Power Cool", usually runs below 3 watts
	Basement: AC Infinity fan and sound baffle to floor vent above. Thermocouple attached to sheet metal duct
	Basement: Duct connection to refrigerator floor vent. FYI Samsung engineers: Not relevant to the refrigerator, but the blue device on the lower left is the top of a medical grade isolation transformer for my electronics workbench, isolating hot and neutral for safety
	Vents at back bottom of refrigerator. No air blows in or out
	Close-up of left back vent. What's that strange bit of light brown foam just inside the vent?
