    On a True T-49 refrigerator, do the condenser fans run all the time? Or, are they supposed to turn off when you open the door? Or when the defrost turns on?

    Commercial Refrigerators do not have a defrost cycle with heat. They use the compressor off cycle to defrost the coil. The one cycle is at 36F to 38F degrees to facilitate this defrost. And that is why the evaporator fans run 24/7.

    Now the Condenser fan only runs when compressor is running. Unless the condenser is dirty, air restricted, or the fan is not up to speed. Then the compressor trips out on high load/temp. But the fan continues to run because they are wired in Parrell.

    Evaporator fans are in the box. Condenser fan is part of the condenser and compressor section.

    Thank you fixbear, I am not a tech but I’m trying to learn as needed. Just trying to keep my business from closing. Every penny counts.., I managed to change the evaporator fans and the temperature control. The ever running fans were a mystery to me. Thanks for your kind reply Sir. God Bless!
