Amana fridge wont keep cold, what can I do?

I do agree with danoyachtcap on his answer however, I have another avenue for you to look at. First let me ask, is the freezer keeping things frozen but the fridge isn't keeping things cold enough? If so I would be willing to bet its one of these two most common things, your defrost timer is stuck or your fan motor on the inside has failed. Not to panic, easy fixes. Somewhere, most commonly on the inside of the fridge compartment in models made in the last 15yrs or so is where the defrost timer knob is located. Its hidden pretty well. If you look up at the top of the unit (inside fridge) you will see not a knob but a hole with a knob inside that can be turned most easily with a simple butter knife. When you turn it you will hear clicking sounds. Advance the timer VERY slowly until the fridge turns off. This will allow the unit to defrost. Ice builds up on the coils of the freezer and blocks air flow to the fridge. You wont see this ice build up as it is behind panels in the freezer. By advancing this timer you have brought on elements located on the coils that will melt the ice build up. (if the elements are good but they are usually fine. not a common thing to fail) You may have to advance the timer 2-3 times depending on how much ice has built up. Now, you may be thinking, I need to replace the timer. NOT usually. I have seen thousands simply stick because of dust build up or whatever and when you help it along, It starts working fine again. If you call out a repairman, he will replace the timer as just a liability issue as he will not take the chance of a return visit or take time to explain what he did. Remember, I am assuming that the freezer is working and fridge is not cold enough giving you this info. Other things to check that most anyone can fix is a fan motor problem. Ask yourself, is the fan BOTH behind at the compressor and the one inside working? If not, nothing fancy there, just take the fan motor out, go to a parts store and get one. Very lengthy I know, but I hope this saves you a lot of money on a costly repair that you can do yourself. Easy as pie. Good luck!

In some cases, if you have ma y people in you family, then your frig will be opened and close more time than you expect. Thus, causing evaporator cores to freeze, you can do one. Or two things., remove all item from your frig, turn it off or unplug it, for about and whole day or over night, that will allow the ice melt off the evaporator core,, . I hope this helps

Many times we think just because we turn the dial, it will fix everything. May times or not, it does not.
In most cases of a refrigerator not cooling could be few things.
1. Clean the dust around the fan on the base of the unit. When that fan is not working you will have NO cooling of the unit.
2. Your coolant is not circulating properly. This will require a professional to make sure there are no leaks in the line and it will have to be re charged or replaced.

If your refrigerator is newer, It could be a lot of things. What I usually do for that problem is to remove the small grill and look under the front of the refrigerator to see if its clogged up with dust
Hope this helps.
