snide comments, what are those !
Your problem has to be in the Air Valve, which directs the flow to the Freezer and Frig. Probably it's clogged with Ice, and you need to do a "special" defrost.
I've got an old Magic Chef that does about the same thing, and I pull the Meat and anything else out of the Freezer, Milk too from the Frig, cover it with a towel for a while (1 hour or more).
Unplug the Frig, and I have a Box Fan which I set in front of it, both doors open, and blow room air into it. Sometimes it takes just over an hour, but, you can see the discharge into the catch pan, and when it sorta stops, you know you got it. Try that.
Have a good Day !
