Are you sure its the condenser fan? The fan is attached to the compressor power and wont run unless the compressor is running. On the other hand the fans inside the cooler will run 24/7 and are designed for continuous duty. If someone has worked on the compressor wiring you may have to re establish the wiring following the wiring diagram. I have seen condenser fans wired in hot areas to run continuously to attempt to cool down a hot compressor or compensate for a worn out or damaged condenser that doesn't get rid of the heat from the system. If that is the case a new condensing unit is probably in your future. Hope this helps good luck.
Check condensor not clogged up, fan working etc. If all ok, try new capacitor and relay. If all else fails, replace freezer (compressor replacement is costly)
Normally compressors fail due to overheating. But just like any machine that may run 24 housr a day 7 days a week, the compressor may just wear out. Overheating is caused primarily by stopped up condenser coils. The condenser coil is the radiator like object that sits close to the compressor and dissapates heat created by the compressor. Also if the fan behind the condenser coil fails because of an obstruction or fan motor burnout the heat will not be dissapated properly. The compressor has protection built in that should shut it off during an overheating situation, but it can't protect it over a period of time where the compressor keeps trying to start and shuts down due to overheating. If you look at the condenser coil in many cases you will find dust and or grease build up so dense that no air flows through the coil. This is simply neglect or not knowing that the coil needs to be cleaned periodically. Also, if you have a refrigerant (freon) leak, your compressor will overheat. The cold returning freon helps to keep the internal components of the compressor cool as well as keeping the oil inside the compressor churning up onto the internal components. If you have a leak, it is not sufficient to just add freon every once in a while. Leaks need to be fixed by finding the leak and welding the leak shut. No refrigeration system should require "gassing up" other than the initial charge of refrigerant. Overheating can also be caused by a lack of air flow through the condenser coils because there is no space around the machine for air to flow into and out of the compressor compartment. If you have recently replace a compressor and it goes bad again, it may be burnout residue from the previous compressor that clogs the lines after a burnout. I hope this answers your question.
Your condenser fan motor at the compressor is either filthy or needing to be replaced. Air flow is pulled over compressor to keep it at a good operating temp. If the fan cannot pull air across compressor it will over heat and shut down on overload. Imagine working in yard on hot summer day and wearing a dust mask over your mouth and nose. Your body shuts down more needing more rest. Same thing with refrigerators, they have to be able to breathe properly also.
Hi, did the whole refrigerator shut down or just the compressor? If the compressor only shut down, the compressor is bad. If the whole thing shut down, it might have went into defrost cycle. Does this help? Vic
Check the relay located on the compressor on the back of the unit. Sounds like the relay is not completely shutting down the compressor. Almost like it is still allowing electrical currents to get to the compressor
