Sounds like the door switch is faulty or there is a broken wire to it.

Hello Michael - Sounds like the temperature control was accidently turned OFF. When this occurs the temperature control turns off the compressor, but does not disconnect the power to the light bulb or other electronics. Let's try activating the freezer by pressing the UP arrow until display shows "4" or desired setting. Allow 24 hours for temperature to stabilize. For future reference you can lock the control to keep from accidently changing the temperature setting. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if the unit's status has changed successfully. Thank you.

what is your model number is then we can get started the

Is the compressor etc. still working? It might just be the display. I have known the display to be run off batteries rather than the pcb itself!

toss it and buy a new one, and make a smoker out of the old one

go to this web site. It has lots of manuals. I found several for your unit. just enter you model number and it shows up with several choices.
Hope this is what you are looking for.

is there anything that's preventing the door from fully closing( too fully)? the door gasket might be the culprit (problem).

Clean cooling coils....throughly. Check door seals.
