    What..?
    I don't understand
    None of it make any sense to me.
    I think there is something you are not telling us.
    Box don't get cold enough but when you replace termination fan delay
    The box drop?

    When u turn off the fan you had an idea?
    It's not flashing gas?

    Let me guess
    You are working on your own equipment.
    You don't want to call the tech back ( too expensive)
    So you will fix it yourself.

    The evap should flash MORE gas with the fan running.

    I think that like a broken clock is right twice a day, you managed to stumble on a defective part, but you need to learn diagnostics.

    I have to agree that it is unlikely that you are a trained technician, because you seem to lack the fundamental knowledge which you SHOULD know....

    I don't get it either!
    Still sounds like you're stumbling and fumbling!

    Yes I think that's what he is doing
    Keep throwing parts untill it's the right one.
    Heater won't be on
    Not in the same circuit as TFD.

    The defrost termination energizes a solenoid behind the time clock, and that circuit is backed up by a separate timer that stops the defrost after a set time, such as 40 minutes.

    Not the "same circuit," but several circuits, working together.

    Freezer Working

    I came this far after 32 or 33 threads I accumulated enough info to understand operation of Walking freezer .And this acquired knowledge help me to troubleshoot in systematic fashion which help to pinpoint the problem. W/20*F box temp i Did'nt see any frost on back wall of evap. after turning off fan i see frost building across the coil which led me to check defrost t/stat which was defective i replace it turn on the unit temprature start dropping. There are people in this wrld who value ur effort this cstmr is one of them.

    So heaters energized throughout defrost cycle until terminated by fail safe?
    This could have been easily determined during initial visit!
    Besides, fail safe should be set at only 25% over.
