The fidge stop cooling 2 days ago but freezer still working. i tried to look in back 2 tell you whats up come to find out theres no way to take back panel off. the fan is running in frige area just not cooling. unit is about 5 yrs old.
If your
cooling unit gradually quit working it's more than likely due to Hydrogen diffusion.This process
is not easy to understand.Hydrogen,having atomic # 1,is the lightest element there is.Almost all absorption cooling units are charged with it.Actually Helium works good too,and it is inert while Hydrogen is extremely flammable and burns with an invisible flame.A lot of older cooling units suffer from this problem and the manufacturers won't tell you about it.The Hydrogen actually diffuses through the pores of the steel tubing.There is no leak in the cooling unit per se.The pressure in the cooling unit may be down about 50 or 60 pounds from what it should be around 330 PSI.The Ammonia will now boil off at a higher pressure than it should.Due to partial pressure law,the Ammonia only sees it's own vapor pressure not the total Hydrogen pressure.So when the Liquid Ammonia boils off in the upper evaporator,it boils off at a higher temperature than it should.This also starves the lower evaporator of liquid Ammonia,and cooling only occurs where liquid Ammonia is boiling off.Please also go to: www.marvinspropanerefrigerators.com
Those are the small radiator like assemblies either under the unit or in the back. Use a long brush if under the unit.
Defrost completely. The unit is probably iced up. Make sure your gaskets are clean and sealing well. If it happens again, we need to find out why. Also...clean the condenser.
The condenser is the coils that are generally located under the fridges...they reject heat into the air. They full of dust and gunk and cut efficiency. They should be cleaned once a year.
Window shopping and introducing lots of moisture into the box is a bad idea. That's what caused the problem. If you're going to put hot tea in the fridge...it will cost more to cool it than leaving it out. Also, some of the steam/moisture will remain in the fridge. Avoid it.

wheres the condensor on the unit?
it worked lets hope it stays cool. heres a question for ya, would it freeze over if you put hot tea in fridge to cool? or if family leaves door open searching for food?
Excuse me! If your refrigerator is compressor based it is completely different from the possible reasons I suggested as it works onexpansion not partial presure law.
