In regard to a small sailing yacht galley fridge, would there be any reason/benefit/need to run the compressor radiator fan any time outside of that which the compressor is running itself ?

Ie just have the fan running off the compressor terminals ??

Thanks !

  • Possibly the compressor radiator fan is used in the automatic defrost function. (Disclaimer: I do not know the details of how modern refrigerators function) – Jim Stewart Apr 27 '17 at 10:03
  • The fan for some condenser coils are temperature controlled making sure all the heat is removed. Turning the fan off it may cause problems with the system's ability to control the temperature the make and model would be helpful. – Ed Beal Apr 27 '17 at 13:30
  • The moment the compressor shuts off, the condenser is rather hot. It is good for the fan to remove that last bit of heat. Is the fridge discharging heat into the cabin's air, or into water? – Harper Apr 27 '17 at 14:07
  • Close as "unclear what you're asking." Does the fridge come with this fan, and does it run forever or just for a period of time after the compressor turns off? – Carl Witthoft Apr 27 '17 at 15:59
  • It is a simple danfoss 101N0210 controller, there is no freezer component so no defrost. currently it just has 12v output for the fan and run continuously (on purpose) regardless of temperature or compressor state. Ive bought a small temperature controlled relay circuit to put in between, so the fan only runs when the temperature on the piping dictates its need. But had got to thinking if that was even necessary, and if it could just be run off the compressor supply for simplicity. – Hayden Thring Apr 27 '17 at 20:06
