Being a sub zero tech and actually fixing that exact model earlier today I would recommend you call a qualified service tech to come take a look. If not, I'll tell you the steps I would take to isolate the problem. 1) check to see if the refrigerator fan, also called the evaporator fan, is running. Just open the door, hold in the switch next to the light switch and listen. You'll hear it easily if it is. 2) If fan is running remove the grate up top, the one you took off to put the condensor fan motor, and see if the right side compressor is running. Don't always go with if its vibrating its running because the freezer compressor or the condensor fan can cause it to happen. Find the high side, or condensor line which is the smaller that comes out of the compressor in the back and runs up front to the condensor, and feel if its hot. Hot = good, cold = bad. Note that all this can be avoided if you have a set of freon guages because that model has access taps already on them. They are wrapped in yellow. If you have guages unscrew the cap and connect the guages. On the outside numbers the needle should be around the 25-30 on the positive side. If its in the green area, the negative, around the 10 you need some freon, and possibly have a micro-leak that needs repairing. If its down in the -20 to -30 area you have a serious leak, more than likely in the evaporator inside the fridge, and you should relay call a tech. Now if the needle jumps way up to 70 or 80 and the compressor is hot, really bad, call tech. and if it does that and is cold, the compressor is just off. Now if your still with me and stuck through this far i'll give you the cliff notes.
If the temp is 55 that mean the fan inside is running, and that more than likely the compressor. Now here are some questions to ask yourself. Are the condensor coils clean? That would raise the temperature. You just changed the condensor fan motor, did you put the blade back on right? If the air flow is blowing across the compressor in the direction of the freezedr compressor, your blowing really hot air from the condensor across the compressor and your temperature will raise badly. Fan draws air across the compressor and through the condensor. Worse case scenario you jacked the control board up inside, which I dont think is the case either. ** check that fan blade **
