My freezer is getting warmer. I was putting stuff in the fridge when I closed it and I heard as though something fell inside. The fridge went quiet. I didn't hear the cooling noise I usually hear. When I opened it, I heard as though a wire came out and there was a hissing sound. I noticed then that the temperature started to rise. I don't know what I did. I seemed to have knocked something out. What could be the possible cause and what can I do to fix it.
SOURCE: outside of fridge condensation; hissing boiling noise
under the compressor there will be rubber bushes which would have got damaged so change the rubber bush and ur problem may get solved
SOURCE: LG Fridge Freezer display has CF error code
Turns out a CF ER is a Compressor Fan problem.
Had a look and the fan was not turning, although it spins freely. Apparently it's a 3 phase 12v fan. I was able to get a resistance measurement across it but didn't know what to expect.
This also explains why it seemed a bit quieter and why the water is a bit warmer sometimes. The valve for the water dispenser is right beside the fan and it's getting pretty hot in there at the moment.

There is a good chance this is the culprit.
Servicing the Evaporator Fan
In some cases, a faulty thermostat may not be the cause of a warm refrigerator or freezer. A warm box may also be caused by a defective fan, a blocked fan, or broken or bent fan blades. If the blades are jammed, try to free them. If they're bent, straighten them with pliers. If this doesn't solve the problem, call a professional service person.
On some refrigerators, the door switch operates the evaporator fan. If the fan seems to be malfunctioning, the door switch could be faulty. Test the switch as detailed in the last page, and replace it if necessary.
Good Luck! Buddy777
