Amana frig I have a Distinctins Amana bottom freezer. The freezer is not really freezing & the frig is not real cold. What could the problem be?

Sounds like you might have a leak in the sealed system and it is gradualy getting worse.

I couldn't find a repairman so I pulled the big thing away from the wall, took off the bottom front plate and the bottom rear plate and unplugged the big beast. Then using a refrigerator brush and a vacuum I carefully cleaned all the dustballs from the coils on the bottom. Then plugged it back in and in about 3 hours it was cooling normally again on a "4" setting.

Get a new defrost timer installed

The fan that should circulate air between the two compartments has failed. These usually have 'sleeve' bearings which can become sticky and fail to start up without help. Go to the Sears/parts website and enter your Amana model number; if you are lucky, they will have a line drawing of your model which can aid in finding how to access the fan:
Sears Parts Dept.
They have info for thousands of non-Sears items and most can be ordered via that website as well.

That could be it.

Because there are many models like the model number listed above your post I will need you to confirm the model number on the refrigerator. The photo below shows were to look for the model number. Some like yours have a simple defrost system and some have circuit control boards. Everyone has these problems with every brand, Your model is Amana and also a Maytag brand. Let me know so I can help you get this going thanks, Sea Breeze

Not fixed but I do not want to spend MORE money to find out what's wrong with this AMANA piece of ****. Apparently, from research on the net, the compressor or motor is not strong enough in this unit to actually do the job...but if anyone has any suggestions, I'm happy to hear them...

sounds like yhour compressor is not runnning, look behind the unit and se of the fan down below is turning and if the compressor is cold, or overheated and redhot

first check you freezer back for frost if a lot of frost defrost the whole freezer ,,, then plug back in and see if it will work..

let me know

Is your fan blowing in the freezer? Frost on the back wall of the freezer usually indicates a defrost problem... defrost themostate, heaters, take back panel off and check evap for frost build up and if your fan in working.
