The past week my Kenmore refrigerator freezer has been running about 15 over 0. It used to be 0 or a bit less on the Walmart freezer thermo. I tried another Walmart thermo that measures both refrig and freezer. Same reading. Called extended warranty service guy. His (expensive?) thermo read -5. He says freezer ok, my thermos bad. I had no grounds to argue with him about it.
So my question is, where can I get an accurate thermo a service guy will believe? Brand name? Source? Service guy says to buy from refig supplies co - he also says the only one in my city only sells to dealers, service guys, etc.
I also found out a previous service guy was wrong, my refrig does have cooling coils. They are in back at bottom-rear (not under) of refrig. He and I tried to pull refrig away from wall in it's little walled-off area but were unsuccessful. Any suggestions on how I (79 yrs old) can move it out to get at coils to clean them? Service guy suggested a leaf blower blowing under frig - says it will clear off rear coils. ???
TIA
