Subzero 501R fan won't shut down when door closes
HI, I'll be able to help you out but I want to go over some stuff that way you'll have a better understanding of your machine so if I have a question it will easier for you to answer. Lets start out with the fan. The fan your hearing inside the machine is called an evaporator fan. Its located at the top of the machine directly over the evaporator coils, which are behind the back wall, that freon goes through in its gas state to cool the machine. The evaporator coild get cold and the fans job is to pull air from the bottom of the machine, across the coils and intio the refrigerator itself and therefor cooling the whole thing. The fan does not extract air out at all. The suction sound you hear is caused from the machine design and the differential in temperature in and out of the machine. The fan will runs non-stop with only 2 exceptions. First being the door getting opened, which opens the switch, I think on that model is located naer the bottom next to the light switch. If the fan is running after you open the door your door switch is stuck or broken and needs to be fixed, but that wouldnt' tmake the temp raise. The second is when the thermostat registers that its cold enough it shuts the fan off. From the age and what your saying is going on I would first check the condersor coils, located behind the removable grate and see if they are really dirty. That would cause the temp to raise airfloe is blocked and the compressor gets too hot. While down there check the fan to see if its running as that too will cause the machine to get hot if not. Ihe coils are clean and the fan is running call a tech because you probably have a freon leak, which is the likely candidate.
