Ok I used an infra-red (16710 TE), a fisher scientific digital, a rubbermaid refridgerator thermometer. Pretty much all are 3-4 degrees higher than the 38 degree set point. The refridgerator believes the temp is 3-4 degrees cooler than the other thermometers. The compressor kicks off when it gets down to 38 but its seems really to be 42 degrees. So it seems the brain of the fridge like it needs to be temperature calibrated or something.
