Trying to troubleshoot the problem. still some air flow coming
through the vents, very light, but not cold at all. what's the
most likely reason? i'm handy enough to be able to change out
parts but need help pinpointing where to start.
other symptoms: a motor kicks on and hums for a few seconds and then turns off.
I had the same problem with my Fridgedare Refrigerator. The compressor would kick on then kick right off. It ended up bein the relay for the compressor. I was lucky, this was the first time I had purchased one of those extended warranty palns so it was covered at no charge.

Hi. There is a valve in the top corner of the frigde that controls the cold Air to flow from the freezer to cool the fridge. This valve called a damper closes when the door is opened. You have to depress the door switch and listen for the fan in the freezer to switch on then feel for cold air to flow into the fridge compartment. The fan could have failed or the damper valve could be stuck closed.
Fridge gets cold air from freezer to cool it. Your freezer is fine but not enough cold air is getting into fridge compartment. U have some dampers or louvers that direct air flow to fridge and if they are not set properly cooling will not be adequate. Check those out.
the damper vent door between the freezer and refrigerator isn't opening to let cold air into the refrigerator compartment from the freezer side,its in the upper left corner in the refrigerator behind a grille,if its closed you wont feel cold air flowing in from the freezer sometimes you can shine a light in this area and look in the other compartment and if no light then the doors shut and this is why its not cooling the refrigerator
Over time debris, ice or food particles can get stuck or lodged into the vents. If the vents are blocked cold air is unable to properly flow through the unit. Cleaning the vents will cause the cool air to circulate throughout the unit once more. Check the vent to be sure there is no ice that needs to be melted. Defrosting the unit with a blow dryer for faster results may solve your problem. Another place to check is the refrigerator seals. Seals are what keep the appliances door closed. Cracks in the seal will result in a loss of cool air. This causes the unit to run continuously, which can ultimately lead the complete unit to shut down. It can also be the reason the temperature has increased. It is also a possibility that your refrigerator is not cold because of the evaporator fan. The evaporator is activated by the door switch, which comes on when the door opens. If the switch is not working properly it will not turn on the evaporator fan.
Please check this link to troubleshoot your problem:-
Check the air return on the bottom left wall of the refrigerator side. Check for cold air flow at the top of the refrigerator when the compressor is running. If you feel no air flow, open the freezer door and see if you detect significantly more air flow after opening the freezer door. This could indicate a return air flow restriction and make sure that there no blocking of air vent at the top of refrigerator section that supplies the cold air from the freezer.Check the door seal gasket on the refrigerator for leaks.
If the vents and air flow paths in the refrigerator are proper, then check the back wall of the freezer for excessive frost. A defrost system problem could be preventing the refrigerator from cooling properly. If you do see excessive frost on the evaporator in the freezer, you may be able to restore proper cooling in the refrigerator by storing your food in an ice chest and then shutting off the refrigerator/freezer and letting the unit completely defrost for about 24 hours. Leave the doors open for air circulation. After the frost on the evaporator has defrosted, plug the unit back in and see if the refrigerator and freezer will cool properly.
If there is still same problem then you need to replace evaporator fan.
This is the generic answer. Use the hair dryer (below) and reset the defrost (look for instructions from Sea Breeze)
Most of these units work with the freezer providing all of the cooling and a thermostat in the refrigerator section controlling a fan in the freezer (where the fan directs cold air from the freezer section to the refrigerator section via a duct in the back).
Look at the rear area of the refirgerator and locate a vent. This vent receives cold air from the freezer to the refirgerator. If you feel cold air coming out of this vent, then there may be no problem, just wait a few hours and recheck the refrigerator temperature.
Look at the rear area of the freezer and locate a vent. This vent provides cold air from the freezer to the refirgerator. Shine a bright light into this vent. You should see fan blades (possibly black plastic). If there is ice on the blades, then you have a defrost problem, and look to other posts on this site for how to manually defrost (or reset the automatic defrost). If the fan blades are rotating, then there is probably a blockage in the duct. Direct a hair dryer (warm setting) through the rear freezer vent and check to see if there is very warm air flowing out of the refrigerator vent (which indicates that the duct is not blocked). While using the hair dryer, you may be able to see the fan blades rotating.
If you do not feel warm air flowing out of the refrigerator vent, then run the hair dryer for a few minutes. (this was my problem, I saw no moisture drip from the vent, which led me to believe that it was more of a dry ice buildup, or that the ice was evaporated (desublimed to be technical).
If there is air flow and no ice buildup on the fan, then reset the automatic defrost. If this is not your solution, either the thermostat or the fan motor is the problem.
please check the air flow to the refrigerator side. it could be a stuck damper motor or damper thermostat. if the fan inside the freezer is running, you should be able to feel cold air coming out off the vents in the refrigerator side. you might have to press the button light switch on the panels to run the fan.
