Hi... I don't know this particular machine... but I'll assume there are 2 separate thermostats as the temps are different. The purpose of the fan is simply to circulate cold air... It doesn't matter if there is one or two compressors as a fault is affecting both sides... I would say motherboard/supply problem.
Is it a digital temp. display? Does this show a low temp? It should show +/-34 degrees. Listen if the compressor runs continuously. It should run for a while and then switch off. When you change the temp setting, as you turn it down, the compressor should stop. If it runs continuously then the likely cause is a stuck/faulty thermostat.Before replacing this, switch off and leave open until unit is at room temp. Then switch on again and monitor. If the thermostat if faulty and the compressor runs continuously you can damage it by overheating. The compressor will run for a good few hours after restart, until set temp. is reached and then switch off automatically. Good luck!
If the compressor kicks in that tells you the compressor relay and board are probably good. HOWEVER, when you say it kicks off right away that is not a good indication! It sounds like a compressor problem. Is the compressor extremely hot or is the condenser coils icing up? If so, I wouldn't invest the money into repairing it, because it would cost more to repair than to replace.
Small refrigeration units like this one like to fail to cool by developing a small leak and slowly leaking refrigerant. THERMOSTAT FAILURE CHECK: A technician will check the thermostat using using a DMM (digital multimeter). But you can suspect the thermostat if you set the thermostat high and the compressor motor does not run, then set thermostat low, and the compressor motor also doesn't run - in other words, the thermostat is failing to start the refrigerator's refrigeration system no matter what its setting - an obvious failure of the thermostat. COMPRESSOR FAILURE CHECK: If the compressor is dying, you would hear the compressor running almost constantly, but not sounding quite right (uneven noise, clunking, tapping). REFRIGERANT LEAK CHECK: If you unit is low on refrigerant (due to a leak), the compressor motor will be running almost constantly, but it will sound Ok.
If the compressor will not kick on what you have is either a bad compressor or a bad starting device. Generally the unit will try and start and after 8 seconds or so you will hear a loud tick. That indicates the relay is bad. If the compressor is bad it will usually make a loud humming noise.
The start device is plugged into the side of the compressor. Unplug the frig. You can simply take off the wires to the start device (remember where they go!!!!!) and pull it off. You have two piece, the overload and the relay. The relay is the piece that is most likely the problem. Some machines will have these put together in a white plastic block. You can shake this entire piece and if you hear loud rattling it is broken. Sometimes the relay is visibly burned and blacked where it plugs into the compressor. Anyway, if you do not have this white plastic relay/overload combo, the relay is a brown square shaped plastic piece. Shake it and see if you hear rattling. If not, chances are very good the relay is ok, and the compressor is locked up.
Compressor changes are expensive and unless the frig is extremely nice and cost a pretty penny, they aren't worth fixing. Relays and overloads should not break $100 for the parts, and any tech should be able to change one in under 10 minutes. So if it's a relay fix that puppy! good luck :D
Good day, If the machine is running and cooling properly, then the problem is internal to the compressor. One or more of the centering springs has broken. No repair possible other than replacing the compressor.
Oddly, these machines have been known to run a long time before failing. However, like everything, not always.
Actually you should check also the thermostat control, if you know how to ypass the thermostat control then do it just to check if your compressor running smoothly, well it should be since it was newly replaced,
well if runs, then your problem is your thermostat, but if not then check your supply current if it is stable or under voltage, if it is fluctuating then better yet put a UPS (un interupted power supply) or AVR (auto voltage regulator for your sensitive appliances cause it might also affect other appliances.
If your electric current is stable, then check the controls of your refrigerator, if it is electronic then try to test it with the service center but if it is manual then try to put starting capacitor for your compressor, it might be hard starting,
Does the fan work? If yes then the compressor has a relay and overload that might be bad. Or it could be a compressor that is bad. If its a compressor then you will need to have a tech verify that it is the problem. If nothing is running then it could be a thermostat thats not switching it on. Let me know if you need any more help with it.
Connect only to an outlet, do not use an extension cord. If you really must use an extension, make sure it is capable of handling the load. Should be a 16ga minimum, 14ga preferred and not exceed 25 feet. If you are having this issue while plugged directly into an outlet, perhaps the circuit is weak, and you should try another outlet.
Other possibilities include: a short-cycling thermostat. This is when the thermostat tries to kick the compressor back on too soon after the last running. OR Your compressor is on the way out. Sometimes the installation of a "Hard Start Kit" will aid a failing or stubborn compressor. If you've eliminated all else, consult an appliance servicer to buy the hard start kit. They typically are a universal fit, and come with instructions.
