I have noticed that the air stops blowing from the freezer into the fresh food compartment. Also, on the back panel of the freezer the frost is getting built. The compressor would not stop. If I turn off the refrigerator overnight then it would start functioning properly for some time. Is it the adaptive defrost board problem? Please advise.

You should be able to check the heater with an ohmmeter as well as the thermostat. Note that the thermostat will open if it gets warm so you have to check it with the freezer cold. Hope this helps!!

If you can get to the wires you need to check the thermostat (clipped to the coils) before you melt the ice and it should read close to 0 ohms. The heater you can check anytime and I don’t know the ohm reading but if it is not open it is probably ok however I would expect it to be somewhere in the 10-40 ohm range. If both of these check ok replace the defrost control.

The fun is operating constantly and the frost has again started to build. Is it safe to assume that the problem is with the defrost control? Is there a way to tesit is or shall I just go ahead and replace it?

The frost keeps building in the freezer and the fun operates non-stop. Also, now the freezer would not become cold enough even after complete manual defrost (this actually started before I replaced the defrost control). Any advice? Thanks

Are you sure you got all the ice out of the coils? Did you reinstall the cover so that the system can receive proper airflow? Is it iced back up again or just not cooling?
