Thread: freezer temperature constantly fluctuates

  1. #1

    freezer temperature constantly fluctuates

    Model Number: FRS26R2AW8
    Brand: Frigidaire
    Age: More than 10 years

    My Frigidaire side-by-side MODEL: FRS26R2AW8 manufactured in 2004 has a problem where the freezer temperature constantly fluctuates from 0 degrees to about 55 degrees over the course of a day. The food and ice will completely freeze and completely thaw over and over again. (Note: When this problem first started, the food and ice would only partially thaw and then refreeze over the period of a week. I thought I was imagining it or the door wasn’t closing. Does anyone know what is causing this?

    I forgot to mention that I have searched internet and there are very different answers. I am really looking for a diagnostic type of proceedure so I can do some troubleshooting.

    The more I think about it, going to zero sounds normal. It may be staying in the defrost mode too long. I will check to see if there is a timer somewhere on the defrost.

    This unit uses a adaptive defrost control board.
    It controls both defrost and the compressor and the damper.
    It is in the control module in the freshfood section.
    Below is a link to info on this unit.

    The next time the temperature starts rising.
    Adjust the temperature control up and down some (not to off), if the compressor fires up then odds are that it is the temperature control thermostat.
    Note that you may have to hold the door switch closed for this to work.
    If this does nothing then unplug the unit and if it starts up when reconnected odds are thatit is the defrost board re: unplugging the fridge reset the board.

    Thank you for the reply. The temperature is hovering above 40 regardless of what temperature setting I turn the knob to. Last week It hovered at or below zero and getting as cold as -10 degrees. When I turn the temperature control knob, the compressor turns on as you said. I will change it out and follow up on this forum.
