The lights come on. The condenser fan runs as well as the inside fan, but there is no cooling and the compressor is not running. I looked for a defrost control, but cannot locate it. The number on the back is GSS25LGMF. I also tried unplugging it for a while then plugging it back in in case something might need to reset.

Re: No cooling at all
I'm suspecting a defective relay/overload on the compressor
to test remove the rear cover, the locate the compressor there should be two wires to it (with power off disconnect them)after that, hook them to the voltmeter leads and carefully plug in the fridge make sure the wires don't touch and verify if you have voltage if so, relay overload is defective after changing and unit still won't power it's the compressor. hope to be of some assistance also on the main board theres a high voltage side you can check voltage from L1 and comp terminal (i think that what there labled, i worked on one some time back) there should be 120 there if not suspect a faulty board , contact if you need more info i could send you a service manual in pdf that i have that could assist you. e-mail's email@example.com

Make sure you dust off the condenser coils to prevent dust build up and overheating due to it overworking. Simply unplug and use a long coil cleaning brush to get rid of debris.
If your refrigerator door seal is broken, warm air is pushing its way inside the unit, thus causing it to not cool properly. Prevent this from happening by replacing your seal and keeping the cool air inside.
Ensure that your thermostat is set correctly, usually 38-40 degrees Fahrenheit.
Defective condenser fan
When this fan is defective, cold air is prevented from flowing through the vents. It may require replacement.
Check if there are clicking sounds coming from the compressor as it tries to start. If there is a clicking, it is one of only two options, either the start capacitor or a bad compressor. A start capacitor is fairly inexpensive whereas a sealed system repair on the compressor is very expensive and often not cost effective. Refrigerator Repair Help Troubleshooting and Parts
1) Failed compressor relay
2) Failed compressor
3) Failed component in the defrost system
4) Bad door gaskets
5) Failed door light switch
Questions to answer -
1) Is the compressor (large black domed item with three tubes (one stubbed) at the bottom back of the frig.) warm or hot? If cool, then you could have a failed relay inside the compressor enclosure. Unplug the refrigerator from the wall, locate where the wires go into the compressor terminal box. Remove the clip holding the cover, and pull the relay off the compressor. Inspect for evidence of burning. Replace if necessary and reinstall all covers. You should always hear a clicking sound when the compressor tries to start. If it does not start, and you hear it click again a few seconds later, then it's likely you have a failed compressor.
2) Was the condenser fan running? The condenser fan pushes rejected heat away from the condenser coil. If it's not running, it's hard on the compressor, and the refrigerator does not cool.
3) Was there thick ice buildup inside the louvers of the back wall of the freezer? Heavy ice buildup here is an indication of a failed defrost control or heater and requires further diagnosis to determine the problem. A knowledge of use of a volt-ohm meter is required, along with a willingness and ability to do some mechanical and electrical dis-assembly and test.
4) Was the fan running inside the freezer? Freezer fan should run when the compressor is running, but not during the defrost cycle (or it would slightly heat up the refrigerator.).
5) Look up my "Tips and Tricks" article on testing your door gaskets.
6) Open the door slightly and look inside as best you can. Is the light
on or off? Continue to open the door until you see the light go on to
confirm the light switch is working.
Following each of the above steps may not help you fix your unit, but will give you an indication of things to look for and describe when you post a request for help when trying top fix you refrigerator.
Robert, Need more info. I am unaware of a "light on the motor". There are three motors normally in a refrigeration system. The inside Evaporator fan motor that circulates air across the evaporator coil inside the box, the Condenser fan motor near the compressor that cools the freon after compression, and the compressor itself. Normally none of these have a light. If you are referring to the light inside the box that turns on with opening the door AND the frig is not cooling, we must go to the very start. 1. Verify power at outlet. 2. Do you see (or inside the box- hear) the two fans running. 3. Is the compressor smoothly vibrating?
Jason, MOST refrigerators get there cold from the freezer side and circulate it via a fan that's also normally inside the freezer. There are three motors normally in a refrigeration system. The inside Evaporator fan motor that circulates air across the evaporator coil inside the box, the Condenser fan motor near the compressor that cools the freon after compression, and the compressor itself. If you open the doors (and sometimes you may have to hold in the door switches) do you hear a fan running? If not you could have a couple things going on: 1. The fan(s) has failed. 2. The freezer Evap coil may of iced over and the fan too is frozen stopped. 3. Your condensing unit:(compressor, condenser fan, condenser coils) has a problem. It is important to know if the compressor itself is running. If there is a loose connection to the compressor via the start/over load relay (normally attaches directly onto the compressor), or if the start/over load otself is bad the compressor will not run. Best way to tell is via gauges but I doubt your frig has ports. Check to see if your compressor is really hot. Could be bad start/over load relay or bad compressor. Try unplugging your frig for say 30 min then, with your hand on top of a cool compressor, plug the frig back in and see if compressor smoothly vibrates for at least 5 min without becoming very hot or shutting off even though fan continues to run. The fact your fan is running TYPICALLY means the thermostat is calling for lower temps and the fan/compressor kick in together.
Please check if the compressor is running. If it is running and the machine is not blowing cold air inside the freezer. You may have either a restriction inside the sealed system or have a leak in the sealed system and all the Freon has escaped. No Freon, No Cool. Not a DIY job.
In order for the machine to get cold at all, the motor has to run. If the condenser fan (fan by the compressor) is running and the compressor is not running then you have one of a few problems. Either the motor is not getting power and that's why its not running, or its getting power and the windings inside are shot and that's why it's not coming on.
When the condenser fan is running you need to check to see if voltage is getting to the relays on the side of the Comp. More often then not, these are the parts that go bad. First Check for voltage to the relays and see it they have 120 Volts AC. If so, check the pins on the compressor that the relays connect to. From this point you are going to need to remove Compressor Relay Cover the clip that holds the relay to the side of the compressor, then unplug them from it and take them off.
The compressor is running, that is a good sign. If you notice any cooling that is not a good sign. Even with the fan not running , the evaporator should have produce some cooling. Could it be that you are a condenser fan running? well, the compressor makes a distinct sound when it runs and you need to confirm that is running and not just the condenser fan.
Firstly- If you confirm that the condenser fan is running; that is, if there is one, that is good.
Secondly- Check and confirm that the compressor is running
Thirdly- If there is an evaporator fan inside the unit, check and confirm that is running.
If all checks okay and there is no cooling, the refrigerant might have escaped through a leak, and there will not be any cooling.
You can extrapolate from my troubleshooting steps to diagnose the wine cooler problem.
Dirty condenser, condenser fan or evaporator fan motor are not running, Ice build up on evaporator and restricted the air flow. If compressor, condenser fan and evaporator fan motor are running but not cooling, then either compressor or sealed system problem.
If the condenser fan is not running while the compressor is running could damage the compressors overload. Yes it's a serious problem if not repaired soon. (Unplug until repaired.) This can cause a weakened internal overload inside the compressor. Thanks, Sea Breeze
This is a Sub Zero and many technicians do not realize that these units most all run on 2 separate systems. 2 cold controls 2 compressors 2 evaporators. They share a condenser and condenser fan motor. What you are describing is most likely a bad cold control. It is pretty common for these to get some age and go bad. If you are very savvy with repairs yourself then if you access the compressor area and feel that the compressor on the right is cool and the compressor on the left is warm then you know that the ref. compressor has not been running. UNPLUG THE UNIT OR CUT THE BREAKER OFF. Remove the shelving from the fresh food section and the cover to the lights and the panel below the lights and lean the back panel forward to access the cold control. You will see 3 wires to the cold control. The green wire is the ground wire of corse. Unplug the other 2 wires remembering their location on the control unit. Take a jumper wire and jump these 2 wires. If when you power the unit up the right side compressor comes on then you know that your fresh food cold control is bad. Replace fresh food cold control.
