Hello all,
I just purchased a used Beseler Dichro 45S color head. I quickly plugged it in to make sure it's working, I noticed that the cooling fan didn't seem to be running. Does the cooling fan come on immediately when you turn the enlarger on, or does it only come on once the bulb has heated up? If it is on, should I be able to hear it?
I picked up a similar head a few months ago. The fan is mounted on rubber stand-offs that had rotted. The fan was jammed. Took a little bit of rubber and some glue to fix it, had to make new mounts.
Turns out since I was quickly checking the head, I only connected one power cord. I just tried again with both cords connected and the fan is working fine.
