Fridge temperatures???
I have a 2008 model Kenmore refrigerator with top freezer.
I have no experience with these newfangled high-deficiency R134a units.
I noticed that my ice cream was softer than usual. Freezer temp was 23F, Fridge at 45F.
I made some temperature measurements and am getting confusing results.
The system seems to be cycling on/off normally.
Air blowing into the freezer compartment is -3F. That seems high for a system that should run near zero in the freezer compartment.
The condenser fan is running and the coils are free of dust. The temperature of the pipe leading from the compressor to the condenser is at 87F. That seems low??? Temperature of the pipe into the compressor is 57F. That seems high??? How can that be significantly higher than the fridge inside temperature?
Ambient is 55F in the kitchen...no I don't heat it and 61F behind the fridge when it's running.
The drip pan for the defrost water has a thin coat of dust and no evidence that there's ever been any water in it. I had similar problems with the old fridge when the defrost timer quit and the evaporator froze up. The small part of the evaporator that I can see shows a thin coating of frost, but no evidence that it's blocked with ice. I can see the pipe that exits the evaporator and it has frost on it. But by the time it travels down 5 feet back to the compressor it's up to 57F.
The only thing that's changed recently is that I replaced the microwave oven with one drawing twice the power on the same circuit as the fridge. Can't imagine that caused anything.
I turned down the thermostat. Too early to tell, but it seems to be colder inside.
The temperatures in/out of the compressor seem to be off???? If the compressor is not running continuously, the inside temps should not have changed???
Anything else I should check before calling service? Or am I just worrying too much???
Thanks, mike
