My refridgerator is a 550 sub zero and it will not freeze in the freezer and the temperature in the fridge is off as well. What do I do?

It is likely the condenser fan is not functioning or the condenser is plugged with dirt. You may need to open the compressor access panel to check. If you can hear the compressor running, and the condenser feels warm, the fan should be running. If it isn't, it probably needs to be replaced.

Model#550 sub-zero This is the second time it has happened to me that the sub stop keeping its temperture called supplier he said clean the fines on the side and inside and should be good.I did all that...

If in the previous cases you could hear the compressor and the fan and now you can't then it's clearly an all-together different and unrelated problem: in the first case everything worked , but not at peak performance because the freon has escaped during the life of the fridge (something normal, it happens to all) so the air flowing thru the coil wasn't cooled enough, now nothing works because the control board of the fridge has failed completely.
This is not going to be an easy fix: at least the control board will have to be replaced and the rest of the components checked for faults - since the board rarely just dies out of nothing. It's a much more complicated job and it's going to be much more expensive to fix. Considering the age of the fridge i really doubt that it's worth the bill - at least $400. Just cut your losses and buy a new one.

Just had the condenser fan motor replaced on my 550 sub zero refrigerator. I forgot to asked the serviceperson the following questions: Does the fan continously stay on and what is the normal sound of...

Good day,
On models with 2 compressors the condenser fan motor runs 24/7. It must since the compressors run randomly and that motor must be on since it handles both units.

Fan noise is subjective. It itself makes little noise but the blade does. If for example the blade was changed from the nylon style to a metal blade (good idea) then it would be somewhat louder.
If the noise is not objectionable then I would use it as is.

The compressor is working but there is no cooling at the freezer section and lower portion of the no frost GE refrigerator. I checked the evaporator coil and there is no frost. What could be the problem?

First make sure your condensor fan motor is running and your condensor is clean. If this is ok and If the compressor is running, and you have no cooling at the evaporator, you have a freon system problem. This means that you have a bad compressor, freon leak, or a freon system restriction. If the refer is under 5 years old, it usually has a 5 year system warrantee that covers everything, parts and labor. Some brands have longer warrantees, Sub-Zero has a 6 to 12 year warrantee. If your refrigerator does not have a warrantee on it, it is not worth repairing. In Seattle Washington , this repair is usually 900 to 1100.00 and we don't recommend it unless it is a very expensive refrigerator such as the 8000 to 12000.00 Sub Zeros. Good Luck, Appliance Specialists

Subzero Model 550, freezer not working properly

Blow out the condenser with an air compressor. Make sure the evaporator coil is not frosted up, if so, the drawer may naot have been closed properly, or you may have a defrost problem, (timer, terminator, etc). Possible freon leak in the high side drain loop. Compressor may not be pumping efficiently, could have a bad condenser fan motor.
