I just got a used working Frigidaire FFU21F5HWB upright

Customer Question

I just got a used working Frigidaire FFU21F5HWB upright freezer and after putting it in my house and plugging it in, both the door ajar and hi temp lights are on, and there is no number on the control panel. I have unplugged the unit for a few minutes, and tried to press the reset for a few seconds, but it doesn't change anything. The freezer is cool, but not working properly. I don't seem to hear the fan blowing either.

At a minimum the display control board has failed. If you can't see a number there is no way to control the temperature inside the freezer. Hopefully that is the only problem but there is no way to know until you replace it and then try to let the unit cool down. This display board is more than a display---it's the motherboard for your freezer so below is a link to the part you'd need to order and replace for your model number.
