Get to the back of the fridge. On the right hand side, there is a metal tube about 4" in diameter which starts at the bottom and goes up. This is a piece of thin sheet metal, which holds insulation against the refrigerant line that goes up the right side of the fridge. The 110 volt heater is located inside of that, near the bottom. The heater sits inside of a small tube, welded to the refrigerant line, and is easily replaced. To get to it, remove any flat sheet metal parts that block your view of the 4" tube (you will need to have a clear view of the bottom of it.) Then you can see the heater. It is on the left side of your 4" tube, metal, about 5/16" in diameter, has 2 wires attached, and sticks out an inch or so to the left. Trace the wires back to where they are connected on your fridge, and remove them, (probably with a small straight blade screwdriver.) It may be necessary to remove another cover or 2 to get to that connection, so remember where all your cover plates came from. Digital cameras are great ;-) . Then, on your 4" tube, unsnap and open the "door" (the metal piece which is a couple if inches wide and 7" or so high,) Grab a hold of your old heater, and pull it up. It probably wont come up all the way so you can lift it completely out, so you will have to unsnap some of your 4" tube above the door. When you remove the old heater, note its position relative to the insulation and refrigerant tube, 'cause the new one goes right back in the same spot. Pull the old one out, and put the new one in. You will know you have it installed correctly when it is snug in its own little tube (you wont be able to see that part,) and there is no side to side play. Then reverse the directions, and put everything back together again. When you re-attach the 2 wires to your unit, don't worry about getting it wrong, it doesn't matter which wire goes with what connector.

Right beside the circuit panel, there is a grill, remove the 4 screws to gain access to the transformer/battery charger. You'll see a double power outlet, one cord is from fridge, the other is from the transformer. UNPLUG Transformer cord and reset breaker.
It will take a couple of minutes for the fridge to change to AC if you have it in AUTO. If everything works fine, REPAIR OR REPLACE TRANSFORMER/BATTERY CHARGER.
Don't forget to rate this answer, Good Luck!!!

Just came across your question, hope its not too late to answer.
Your freezing problem for the fridge section is likely caused by
1) the thermistor has worked itself loose from the cooling fins.
2) the thermistor is no longer on third fin from the right
3) the thermistor is failing.
