yes it must be shut off and completely defrosted.with doors left open it usually takes about 2 days. what happened if you look at the back wall in the freezer from the inside you will see a bunch of ice and there is more behind that panel you are looking at. it froze up the coils so that no air will get through them. good luck rich
You need to unplug the freezer because the compressor is getting hot and the reason the compressor is trying to start but cannot. This clicking is possibly a defective=> WR7X225 Start Relay or a defectve WR62X10058 Run Capacitor If you have an OHM meter you can test the compressor windings. as in the instructions here=> Unplug the freezer and remove the back panel that covers the compressor. There should be 3 wires going inside the cover of the compressor. Mark all 3 and mark their location so if compressor is OK you can put them back in same order. The plastic cover may snap on and you may need to squeeze the sides to unlock the cover and sometimes there is a metal clip holding the cover in place. Remove the cover. May look hard but it's simple. There will be three connections under the cover and 2 will go through the start relay. Unplug them leaving the three prongs exposed. They may be marked R =Run, S=Start and C=Common. Set your meter on continuity and then begin by testing 2 at a time until you have checked S to R and R to C an C to S and S to R again. You should get a reading all the way around. If no reading between any of the pairs as you go around you should get no reading between any two the compressor has an open winding and is defective. Then if it passes that test then touch one probe to R and the other to the copper pipes or clean metal on outside of compressor, then S to metal outside and C to metal outside. If you get a reading this way even just a little. The compressor is a burnout. Then let me know what you find. Thanks, Sea Breeze Have you already solve this problem?
