    possibilities......

    oh boy ! to think of all the possibilities.

    -defective thermostat
    -freezer/refrigerator settings not set at optimum settings
    -defective air damper, (allowing too much air into refrigerator compartment)
    -ice blockage in main air duct in freezer compartment
    -defective defrost control
    -air leakage around door gaskets
    -overloading the refrigertor with product not allowing the door(s) to fully close.
    -excessive opening and closing (kids, and some adults)
    -warped door(s)
    -defective defrost heater, (but not likely)
    -missing/broken air deflector(s)


    and lastly, it's freezing product in the door, "because it can"

    dannygo, if you are being graded on this one, at least share the 'A' with me

    29) If you have a conventional unit with no frost on the evap. coil what would be the reason?

    a) leak
    b) air
    c) restriction
    d0 bad valves


    39) Would a compressor draw LRA if the windings were shorted?




    54) If your compressor was trying to start and cycles off it could be
    a) LRA
    b) open winding
    c) shorted pump
    d) bad start relay
    e) bad int. overload
    f) bad start cap
    g) all of above

    29) all the above would yield little or no frost on the evap, however 'all the above' is not a choice. soooo, go with the most obvious, leak in the system. no refrigerant, no refrigeration effect.

    39) and would it ever draw LRA! and a whole lot more! shorted windings will theorectically draw infinite amount of amps until the safeties in the system open and/or trip.


    54) tricky question........

    your best bet would be 'all the above', although some of the choices are the least likely to be the cause, but all of them could cause a compressor not to start.

    Now these are on frost free units

    9) How is a 5 wire timer different from a 4 wire timer?




    28) What are two things to check, if frost free unit was dead but did have lights?



    42) What would be another way to check an evap fan motor that's not working, without an ohmeter?


    49) What could cause the defrost heater to stay on while the compressor is running?


    68) What's another wat to check the defrost heater without an ohmeter?



    Done!!!!!!!

    Yes, and all of us will need more than one book to get a good spectrum of basic knowledge.
