Hello, Do you notice frost accumulating inside the freezer back wall? Do you hear a fan running inside the freezer?
No frost, fan does not run when alarm lights are flashing. If I switch unit off and on again, lights stop and fan runs, but sounds laboured.
Ok, thank you for those info. If you go to the back part of the unit, once plug in, would you notice the compressor( black steel ball ) run? vibrate? or hot to touch? ( Be careful, it could be too hot to handle ).
Removed back wall panel, cold air is coming out vent, when I turned the rapid cool setting on the damper did not open, I can manually move it but it does not open on its own. If this is the problem would this cause the main fan to stop and cause the freezer to heat up?
Hello, I the damper is not opening up, it would not affect the fan and the freezer. The fan would only stop and the freezer would warm up when ever the freezer is defrosting. You could probably saw the freezer while it is in defrosting mode. But that would just be temporary. After 40 minutes, the fan would run and the freezer should start cooling back.
Your problem now is the damper. Why would it not move on its own. Try to leave it in the open position and observe if the fridge would now cool down.
Damper is spring loaded, assumed that it only opens when the fridge requires to be cooled? i.e. when it get above set temperature it opens via thermostat?
Ok. Then it could be the thermostat that sends the signal to the damper, or the damper itself is defective. If you can remove the wires to the damper, let us say it has sockets, then put something that would hold the damper open and see if the fridge would cool down, this would verify that the freezer is working fine plus the unit itself has no problem regarding refrigerant or cooling system is concern. Then you can use it temporarily until parts arrive.
