Question about fan speed

[nnbreeder]

I have an incubator that has an electronic thermostat on it and a fan that looks like one in the back of a computer. Since the thermostat just kicks the element on momentarily the fan is wired up direct so it runs constantly.

The problem is it moves too much air and dries out the eggs even with the water trays full.

Is there any way to slow the fan down with a resister or reastat without hurting the fan or causing a fire hazard?

Does this setup have a heating element and how many watts are you talking? You have two ways you can do this by using a ceiling fan speed switch if your wattage is acceptable, a dimmer switch will work too and is much cheaper and holds about 300w, too many watts will damage your switch. Heres a couple ways of doing this but you will need a small wall box and a few wire nuts. You would need a super resistor for this setup if you could find one and they sure are not cheap!

The first way only controls the speed of your fan but the heating element is directly on 120v and will run much hotter because of the speed of your fan unless you use two speed control switches.


The second way is to wire the fan and heater both to the fan switch if your fan switch can handle the load, hope this helps.




One more shot, try splicing in a 200w bulb or less to see if this works.

Thanks, I think I will wire in a dimmer on one of my older models and see how it goes.

Let me know how it goes
