My commercial cooler has stopped cooling for no reason. Everything is still working and running but it doesnt cool. Once in a while it will also make an audible 'pop' noise. Its coming from below the unit. I opened it up and it all looks fine and clean, theres no build up or frozen over. Any suggestions?

Re: Cooler no longer cooling
That POP noise sounds as though it is the overload on the compressor. Although personally I would describe it as a CLICK. If it is then you are either looking at a start device failure (relay or capacitor) or more likely a compressor failure. If you check underneath at the compressor side (black circular unit) and put your hand on the compressor if it is hot you are probably looking at a new compressor. Unless you have electrics for the compressor the only real solution is to have this confirmed by a fridge engineer. If it is the relay I would expect a bill of around £80 if it is the compressor thn it can be between £200-£400 depending on the size of the compressor. Hope this is of some help.

Let it sit out for a while to avoid any heat damage. It should work once again once it has cooled this is a security for the PS3 to protect the internal components. To avoid overheating place PS3 in a well ventilated place where it can get a steady flow of cool air. Do not place it on carpet or any other surface that might insulate the system. Try to reduce play time take a break once in a while. If you would like longer game time buy an air cooler that hooks up to the PS3 and increases airflow and keeps it cooler longer.
There are generally 2 reasons why this would happen. The defrost timer or heater has gone bad. Or, the fan is not working. Because you state that it runs all day long, I would think that the coils are now a block of ice and cannot cool. In any case, manually defrost it now. Turn off the power and use a hair drier on low (not hot) setting. This should fix the electrical cost for now. Then you can determine if the fan is running properly, or the defroster.
Few things to check here. If the compressor is not running then the problem may be a bad thermostat or the compressor start device (ptc starter). Most common would be the thermostat on wine coolers. Also need to check if the fan is running. If everything is running then you have a sealed system problem. If the fan is the only thing that is not running that will cause a no cool situation.
