Long story short, i opened the panel in the back of the fridge to find that it was frosted over.

manually defrosted (unplugged and used the hair dryer).

i found the fan doesn’t turn on all the time. The fan only turns on when i restart the fridge. Then it stopped after it’s “initial cycle”(?). (I can tell it is on or not because i put a piece of plastic that it touches the fan blade.)

I turn off the fridge one in a while so that it defrosts. So far I had forced defrost manually using the FD option. (Once Last night and one this evening). The drain is not blocked Because water does drip down when I turn it off.

Problem persists. I changed the temperature sensor behind the panel. Same problem. I’m asking if you have any suggestion or solution.

i will have to call for service, (I just don’t like the fact that there is no guarantee that they will do it right the first time. No guarantee that the problem will not happen again.) i have the Ice maker Turn off because it freeze and therefore no water going thru the system.

Thanks for your attention.
