    Default Moisture in top mount freezer

    Hotpoint
    Model: CTX18CAXCRAD

    Seems to run a lot.
    Has moisture on ceiling and walls of freezer.
    Df stat checks good
    Df heater checks good
    Temp control does not seem to cut off until in or almost in the off position.
    Tried to recalibrate temp control.
    I expect it is past recalibrating. Turn the calibration screw a little each way and it clicks.
    Also, the evaporator fan shows no constant continuity. Did a few times with two different meters. It did not today, but hooked cheater wire directly to it out of the fridge and it ran.
    I do not understsnd that.
    Mostly likely cause of moisture?
    Temp control not turning off as it should?

    Odd for sure!
    Maybe the motor has moisture inside as well.

    Mostly likely cause of moisture?
    Wide temp swings, air leak ( gasket, area where screws are, area when tubing pass through the cabinet would be prime suspects.

    Temp control may be NLA.

    Have found no air leaks anywhere.

    Is it possible on this model for the compressor to still be running when df kicks in mixing warm air with cold air thus causing the moisture?

    No models should do that.

    Well I have no idea what the priblem is. I thought maybe something in the timer might be sticking and letting the compressor run when it should not be.
    I did remove the drain tube on the back and clean it and the piece of drain in the fridge itself. Found what looked like a pebble in the p-trap part partially blocking it. That and not sure the drain pipe itself was properly connected to the piece in the fridge. Thinking there might be a slight air leak in the round part that snaps in the back, I put a little bit of gasket maker on it.
    All that being said, I have misplaced the timer!
    Probably take it to the scrap yard.

    That is very possible.

    Let this thing run part of 2 days. No moisture but it seemed to run constantly while holding steady temps. I have to turn the temp control all the way to off to get it to shut down even with holding the set temps, near zero and 38.
    It was holding the temps, but I had the dial set past the recommended settings by a good bit.
    It does have a tap on it where someone had refilled refrigerant before.
    One thing I suspect is it is a leaker.

    Where the cold cones from the freezer, there is styrofoam insulator piece. The temp probe goes behi,d it and down.
    Is that piece supposed to cover the part of the probe that goea around it?
    What I am wondering is if it keeps the warmer air from the ff compartment from mixing with colder air in the freezer which might cause condensation.

    Doesn't the cap tube from the temp control run in a groove around the air opening from the freezer?

    Yes, it dors around the sides and looks as though across the top too. I think there is a piece torn off of the back at the top and sruck in the groove at that point. It looks like it is supposed to cover the probe at that point.
    Makes me wonder if the splice where I pushed if back on caused the moisture problem.
    I turned it off yesterday. I intend to mark the timer dial, turn it back on, then check a few hours later to see if timer is moving.
    I don't understand having to turn the temo control all the way to off in order to get the fans and compreesor to shut off unless it is faulty.
