ICED UP WALK-IN COOLER WITH HIDDEN PROBLEMS. Evaporator was frozen up with no clear reason to be found at first. My first step was to check the evaporator for proper air flow once the coil had melted. Then work my way back from there. The defrost clock, solenoid valve, pressure controls and so on.

    What is that thing wraped around the coil?
    It is Rick with sleeves rolled up ready for toil

    Full of ice and never cleaned
    PM service never intervened

    After some rather gymnastic feats
    it once again removes the heat

    Then Rick jumps up into his van
    drives away as fast as he can
