My freezer part freezes and no cold air goes into the refrigerator part. I have to take the back off of the inside of the freezer on the inside and defrost the coils and the air holes that lead to the fridge. This happens about once a week. Do I need to buy a new one or can this be fixed?

Re: fridge freezes up
This could be caused by one of three things. Either you have a bad defrost timer or a bad defrost element, or bad wiring related to those two. Unhook the two leads to the defrost element and check the resistance of the element. If it is open, replace the element. If it reads resistance, replace the defrost timer.

All the big cooling happens inside freezer compartment. Freezer gives little cool air to fridge compartment. Now when the vent blocks that little cold air cannot go into fridge compartment. Thus your freezer works good but not fridge compartment. Milk goes bad but frozen meet keeps good.....
Vent freeze up either due to defrost problemt, defrost drain line problem, Evaporator fan problem or even can be your damper motor not opening due to unit failure or frozen damper door.
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.
when you open the freezer door do you hear the fan blowing?all that happens is the evaporator coil in the freezer gets cold,the evap fan blows the cold air from the freezer and into the fridge side,there are ducts on the bottom left side where the air return sto the freezer,if that's blocked the fridge will get warm,also if the fan is blowing depending on your model you could have a damper,it's in the fridge section up top where the cold air blows into,all it is is a door that opens and closes to let the air in when the fridge section gets warm and then it closes when it's cold enough,if the damper is bad it won't open and let the air in,sometimes it gets stuck in the open position and things start to freeze in the fridge section.if you can't figure it out send the model number and i can see what model you have,open the fridge door,look up on the right side near the ceiling and you should see a tag with the model number.good luck and have a great weekend.also from the bottom up in the freezer,remove the second bin of food and touch the back inside wall of the freezer,if there's frost or like snow on the back inside wall of the freezer you have a defrost problem,let me know what you find.
Most times this is a bad cold control, but there are other things to check for. Make sure the condenser fan is working and the coils are not covered with dust. A separated heat exchanger ( small capillary tubing soldered to the large suction line ) can separate from one another and make the fridge run too long. - tape tubing back together. A poor working evaporator fan motor could also make the fridge run too long and freeze - replace the fan motor. An inefficient compressor or refrigeration system could make the fridge run too long and freeze - have a service tech check this out. A misaligned control settings, make sure the air damper and cold control have not been bumped and are out of normal settings. Stuck open air diffusers or air dampers are becoming more and more common for allowing too much air to be blown into the fresh food section and freezing things. On all frost free fridge's the freezer temp air is blown into the fresh food section, if you have "easy" to freeze items ( eggs, veggies in water, etc ) in front of or under where the freezer temp air comes out, they could freeze
Check the cold control, and also the air deflector. As you know, the deflector directs the freezer air toward the front of the frig and the rear of the cold control.
Well first of all solution # 1 pertains to household refridgerators..RV models have no fan inside maybe outside,But I would find out if it gets cold/freezes with 120 volt and or LP(propane) and look trrough the internet and download your model service manual.
Behind the back wall of the freezer about halfway down, probably behind the light bulb (if there is one there) there is a fan. My guess is that the fan isn't working, or is slow. To test, open the freezer door, then hold the door switch closed and listen for the fan.
This fan should be blowing air up the back of the freezer, and send some of the cold air through a vent at the top of the freezer into the fridge. The air then descends through the fridge and reenters the freezer through a vent at the bottom. If the fan is broken, or if the upper vent is somehow blocked or broken, the cold air will enter (rather than exit) the fridge side at the bottom vent. Because cold air tends to descend and warm air rises, the cold air will freeze the stuff at the bottom of the fridge, and the thermostat (at the top of the fridge) will say it is warm.
Usually on bottom freezer fridges, there are two vents at the bottom of the freezer compartment where the cold air goes back into the freezer (cold air enters the fridge through the vent at the top/back of the fridge.)
If the vents at the back of the fridge are covered, the cold air will settle to the bottom of the fridge after it enters, and freeze your vegetables. The problem could be caused by ice build up in the evaporator coil of the freezer section also, but this will probably warrant a checkup from a pro.
One thing that can cause ice to build up inside those vents is moist air seeping in through a faulty door gasket. A thin coat of ordinary Vaseline on the gasket surface can help it make a better seal.
Check that all seals are completely sealed, especially the freezer door. If the freezer door leaks, the bottom of fridge will constantly be cold. Also, check the flap in the inside back. It controls the air between freezer and fridge. It may be putting more air flow to fridge rather than freezer. The cold air will sink low and keep the drawer are colder.
