Not cooling or freezing, tank in the back of fridge is hot

If it has fan to deliver cold air, and it is not working, cold air is stuck on the begining. So your fan could be dead. And I suppose, that compressor is running all the time. Even compressor could stert freezing if fan does not deliver cold air in fridge. The other option is, that there is not enough gas in the compressor. In this case compressor vould not be freezing, but line, going out of compressor has to be hot, if it is not, there is no gas.

Checked Freezer Fan is working. Also checked defrost Fuse in freezer.
To checked freezer fan is working or not open freezer door press Door Switch and checked Cold air is coming from duct or not.

check the damper vent door between the refrige and freezer and make sure its opening up to let cold air from freezer into the refrige,sometimes they freeze up and cant open and close when called upon to do so,if so deice it with a hair dryer,the side being hot is good telling you the compressor is operating correctly

Defrost the freezer, it's sound like it's iced up.

The black thing is the compressor. It should run warm but not hot. This usually indicates it's time to clean the condenser coils under the refrigerator. Try using a long soft brush and your vacuum cleaner.

there is another fan at the bottom, rear, of the refigerator. remove the bootom panel and look at the cooling fins to make sure they are not bent into the fan blades. Caefully bend the fins away from the fan. this should improve the cooling of the refrigerator and get rid of the hot spot on the rail between the refrigerator and freezer.

Your compressor is seized and is cycling on intenal overload, you will have to get someone out to get a price at replacing the compressor for your fridge.

Check the back wall of the freezer for ice buildup.
If yes, a defrost parts problem.
Check the freezer fan. Is it running?
If no, replace the freezer fan.
Check the condenser fan at the compressor. Is it running?
If no, is compressor hot?
If compressor is hot replace condenser fan motor.
If compressor is not hot.
Replace the compressor start relay.

hi have you cleaned the matrix best done by blowing with air but a soft brush can work,make sure that all the cooling vanes are clear
hope this helps ian

Condenser is in need of being cleaned badly or your fan motor to cool the condenser is not operating. Compressor is overheating. Removed the panel in back of the refrigerator and clean the condenser so air can freely pass over it for heat removal. Allow compressor to cool off before restarting it.
