    Default Fridge no longer cold

    Model Number: 596.66032600
    Brand: Sears Kenmore

    Hello,

    I wanted to ask for some assistance with fixing my Kenmore Fridge/Freezer.
    The fridge is not cold anymore but the freezer works. Upon reading some similar posts I have figured out I may have a defrost issue.
    I went ahead and checked out my condenser coils and found them to be almost wholly encased in a block of ice. After manually thawing them out the fridge seems to be working ok, so now I have to figure out which part of the defrost system I need to fix.
    I was wondering if someone could help me out with tear-down diagrams for my specific model. It is a bottom freezer style.

    Thanks!

    You would need to ohm your defrost thermostat(WHILE ITS FROSTY) with an ohm meter to check for continuity. Normal ohm reading will be 0-1 ohm.

    The defrost thermostat snaps on the top of your evaporator coil.

    Here's the defrost thermostat for your model:
    Manufacturer's Number: 67003426


    If that checks good, then its likely the control board.

    Here's the control board for your model:
    Manufacturer's Number: 12868513

    The condenser coil isn't in your freezer, thats the evaporator coil.

    The condenser coil is underneath your refrigerator.

    Whoops! I was reading and typing something different. thanks for the clarification!

    Do I need to check the actual heating element as well?
    How exactly do I get at the control board in the top part of the fridge? I didn't see any screws holding the cover on.

    I will check the thermostat tomorrow with my multimeter.
    thanks!

    Yes, also ohm test the defrost heater, that should read about 30 ohms.

    Here's the repair manual for your model, page #32 shows how to change the control board:

    So I un-plugged the wiring harness and put my test leads in the plugs for the orange and brown wires. I made sure that I unplugged the heater plug as the orange wire was split onto that.
    defrost thermostat: .04 ohms
    defrost heater: 33 ohms

    Would that also explain why my fridge hasn't stopped running in the past 3 weeks, except for the times I have un-plugged it? I tried adjusting the temp down to the lowest setting, but it still kept going.

    I will see what the local cost is for the board here and I'll compare shipping it in.

    Thanks Jake!

    Yes, that would explain it.
