SORRY, I HAD TO FEED MY 3 KIDS. HOMEWORK. ETC
first i need for you to check the freezer sections of both machines. in the rear of the freezer there are evaporator covers that protect the evaporator. if they have any frost on them let me know.
THe evaporator covers on this unit is under the white panel under the bottom drawer. Am I correct? I am familiar when they frost over and have blow dried them many times. When that happens there is no smell. I DON'T BELIEVE THAT IS HTE ISSUE.
if there is no frost or ice building up then you are good. put your hand near the back of the inside of the freezer area. do you hear a fan running? and is it blowing cold air? THE FAN IS RUNNING AND IT IS COLD AIR.
if the temps are ok, then it probably is, and that is good.
we can then rule out a defrost failure. and have to deal with the smell. is it more pungent in the freezer section or ref section? THE TR AND TF MEANS TOTAL REFRIGERATOR AND TOTAL FRIDGE SO THAT'S NOT APPLICABLE ON THESE UNITS.
if it is the freezer section, then yes, i am afraid you will need to call in a service tech so he can better take a look. because you could have a sealed system issue. and if it is not taken care of soon, it could lead to big problems.
please do these checks and let me know what you find. WHAT ABOUT THE LITTLE BR UNIT? THAT'S THE ONE THAT ISN'T WORKING AT ALL. IT RUNS BUT IT DOESN'T CHILL. IS THERE ANYTHING I CAN DO FOR THAT??
