Kelvinator express cool n476c is not freezing. This did happen once before and mechanic pulled apart to defrost. I have ensure the vents are not completely covered now. Should I do anything else?

Your self defrost mechanism is not working. Need a heater element.

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.

first look for an air vent in the bottom of the fridge(a small grill on the inside wall) & make sure nothing is blocking it, like bread eg: if there isn't then unplug your fridge & let it defrost, check the drain outlet in the back of the freezer, sometimes a small item like a frozen pea gets into the drain & the water freezes around it causing the air not to return to the freezer from the fridge, to push air into the fridge you must be able to get air out or it presurises,

The vent from the freezer to the fridge can be blocked with frost and is preventing the flow of cool air to the fridge.
This can happen if there is frost build up due to failure of the auto defrost timer.
So please check on the fan section , remove panel and see if there is frost or block, if so check the timer Heater and the thermostat.

Hi

Check the back wall or floor of the freezer section for frost. Check the freezer or evaporator fan to see if it is running. Check the condenser coils under the unit for blockage from dust. Check the condenser fan to see if it is running.
If you have frost in the freezer there is a problem with the defrost system and the freezer will start to warm eventually as well as the fresh food section. If that is the problem you can check the defrost terminator, defrost heater/s, and the defrost timer or adaptive defrost control If used on your unit or the main control board if so equipped. These things usually require dismantling the freezer and other areas of the refrigerator to be checked.
You could defrost the freezer by disconnecting the power to the refrigerator and letting it sit for at least 24 hours with the doors open to allow the frost to melt completely but it will build up again in 1-2 weeks and start the warming up again.

Sorry to hear about your problem.

Sounds like you have a defrost issue. Hence your unit is not defrosting. All of this apply's if your freezer side has ice on it. If not. you have other issues, this does sound funny, but this is why your refrigerator side is warm, or not cooling.

Here is a list of some things that can go wrong.
1. Defective heat coil
2. Defective defrost timer
3. Defective defrost sensor
4. Defective Fan
5. Defective compartment inlet damper (on some models)

You should call a service company to resolve your issue.
