Freezer side is working fine. the fridge side appears not to be as cold as it use to be. a few days ago my kid left the door ajar all night. how ever it should be cold by now. there is power I can hearthe motor running. both setting are on the coldest they can go(top one and one by the crisper drawer.

With the door ajar created lots of moist air into fridge need to check fan that feeds the fridge ---the freezer air is what is used to cool the fridge when doors are left open moisture turns to frost / ice and builds up in and on fan stopping it or restriction flow some times u can get lucky and catch the problem before fan burns up [causing need for replacement ]usually to or three screws access the fan check for function dont touch wiring or blade if ice build up unplug unit and with a hair drier defrost ice so fan can turn freely than make sure that air flow is clear to fridge plug in and check for cool air if fan not running will need to test fan may have burnt up and needs replacement

When a refrigerator door is left open the freezer will continue to run to keep it cold and since it can't cool an open area it will freeze up on the inside, to resolve this you will need to unplug the fridge and open the freezer door and allow the freezer to thaw completely, once it is thawed you can plug it back in and everything should go back to normal after a 24 hour period
