When I plugged it in, all the main functions work fine, but the fan comes on when the compressor switches off. even if I turn the unit off at the power switch, the fan runs. I guess that is fine, but I'd kinda rather the fan run while the unit is cooling and already noisy. Im assuming its a simple wire switch, I just dont know which one.

Thanks!
It would be wise to unplug the whole thing until you figure out what is going on. Something is wired wrong, and it could be serious.

I would suggest rethinking your fan approach. For most applications, having the fan run only when the compressor is running provides almost no benefit. Running a small fan continuously is a much better solution. A small computer case fan (12V) powered by a cell phone charger (5-12V) is the most common method.

RE:wiring issue- You haven't provided enough information to know for certain, but the most likely scenario is that you are cooking your compressor motor by completing the fan circuit through it.

The unit is unplugged at the moment till I work this out, but I appreciate the caution. If its better to leave it always on, I guess I could wire it as an always on outlet then? Id rather not have to wire up a whole nother outlet and then plug a cell charger/fan combo into it, and I already have the 110 fan.

Here is the wiring diagram for how I wired it.

I guess I could just leave the fan off entirely as well, Is it really any benefit?

Thanks for the help!

Usually the fan is of benefit in a chest freezer. Ok I see the problem, your fan is wired incorrectly. The black wire shown on your fan actually needs to connect to the red wire that goes to pin 2 (neutral). What's happening is the fan is drawing current through whatever is plugged into the cooling outlet when the cooling contact is open. (If the fan has a black wire and a white wire, the black wire should actually go to the wire coming out of pin 8, and the white wire should go to the wire connected to pin 2.)

ok, that makes sense. I figured it might just be a switched wire, just wasnt sure which one to switch. No color coding on the fan wires btw. Thanks! So not worth it to run the fan? its a tightly packed kegerator....

Sounds good! It sounds like many people are saying the fan does help but usually a small computer fan is used and it is let run all the time, rather than switching it on just when in cool.

If you don't understand electricity, use an approved schematic that does what you want. There are several schematics that do exactly what you are wanting, along with many posts questioning why they don't run the fan full time. There are schematics for that as well.

DIY doesn't mean you have to do everything yourself. It isn't like you built the fan, outlet, controller, etc.

You are running an amount of current (as a guess, ~double the fan's current, at ~half the wall voltage), through your compressor. Most likely it is too little current and voltage to turn the compressor motor, so it is just heating it up.

I have an old garden hose sprayer that I could have used to serve beer with, but it didn't prevent me from buying a SS faucet. A computer case fan can be had for the price of a plastic picnic/cobra faucet, or less (free) if you have an old computer sitting around. If you don't have an old cell phone charger in a drawer somewhere, DIY may not be your bag. Hording kind of comes with the territory, otherwise it is usually cheaper to buy prebuilt.

Whatever the wattage is of the 110V fan you are using will go directly into your kegerator as heat. As an example, if the fan is 40W, you will approximately double the run time of a typical kegerator, plus paying to run the fan as well. So, the actual kegerator electricity usage will be tripled compared to no fan. A typical computer fan is 3W at 12V, and ~half that using a 5V cell phone charger to power it.

The outlet for the fan doesn't have to be part of the controller box. You can plug the cell phone charger directly into a wall outlet, although I don't understand why you feel wiring up a $0.79 outlet into your controller box is such a chore.

Fans are very helpful for virtually all places where post boil beer resides. Depending on what type of kegerator you have, there are different places where the fan works best.

"If you don't understand electricity, use an approved schematic that does what you want. There are several schematics that do exactly what you are wanting, along with many posts questioning why they don't run the fan full time. There are schematics for that as well."

I used a schematic I pulled off this forum that made sense along with the diagram that came with the unit. Oh, and apart from my fan issue, it worked. I couldnt, despite my searching first, find one that included a fan. If you have those links, please, post them for me.



"DIY doesn't mean you have to do everything yourself. It isn't like you built the fan, outlet, controller, etc."

I'm not even sure why you included this. It's totally irrelevant.



"I have an old garden hose sprayer that I could have used to serve beer with, but it didn't prevent me from buying a SS faucet. A computer case fan can be had for the price of a plastic picnic/cobra faucet, or less (free) if you have an old computer sitting around. If you don't have an old cell phone charger in a drawer somewhere, DIY may not be your bag. Hording kind of comes with the territory, otherwise it is usually cheaper to buy prebuilt."

Perhaps you misunderstood. I wired in a 110 computer fan to the circuit. One similar to those found in computer cases. Did you think I stuck a box fan in a 4 c.f. kegerator? I in fact do have an old computer fan and cell charger sitting around, Its what I made my stir plate out of. Myself...


" although I don't understand why you feel wiring up a $0.79 outlet into your controller box is such a chore."

A chore, not really. But I'd still rather not if I didnt have to. Plus I'm using a rather small project box and there isnt room for a second outlet. And where did price come in as an issue?!



"Fans are very helpful for virtually all places where post boil beer resides. Depending on what type of kegerator you have, there are different places where the fan works best."

Perhaps the best attempt at being helpful and useful you've managed yet. It's your standard mini fridge modified to fit two 5 gal cornies with a tower in the top. co2 tank external. Oh yeah, I did all that myself too.... So where is the best place for the fan in this setup?

Don't be such a condescending prick CWI. Just because I dont know everything doesn't mean I don't know anything. Look how simple the answer was from Porcupine 73 and how nicely he delivered it. Whereas you, didn't really help, just spouted off and made assumptions.

One nice feature might be able to be able to switch the fan off manually though. Some people I've seen say that if they open their kegerator with the fan on then it blows all the cool air out quickly. But that might be more for chest freezer operations than uprights. Your box fan idea makes me think of trimming down the blades on an old ceiling fan to mount under the lid.

If you got that as a verified schematic off the forum, you obviously copied/redrew it incorrectly. Anyone with basic electrical knowledge would have immediately seen it was incorrect, and told the person who posted it to take it off.

Really? You were completing the fan circuit through the compressor. If you had left it plugged in as-built, it could have fried your compressor (and fan), and in a worst case scenario caught it on fire.

So, the schematic you pulled off the forum was just used as a basis for you to add your own fan circuit too? That explains your posted schematic (which should be replaced or pulled off immediately, lest someone gets a hold of it). Had you asked for a link to a schematic prior to deciding to play engineer yourself, or at least posted your homebrewed schematic for vetting prior to actually using it, that would have been a much better approach.

Well, considering I mentioned using a computer fan, and only got the response that "I already have a 110V fan", coupled with your demonstrated wiring aptitude, and that there was never any mention of the size/type of your appliance; I had a pretty funny picture of your setup in my head, and went with that.

I can provide links to several people with various household fans, up to dual 12" diameter ones, inside their kegerators.

Again, the only information you provided was that you would 'rather not' wire up a "whole nother" outlet if possible, and already bitched about not wanting to buy a $2 case fan because you already had a 110V one (with no size/type communicated yet).

Had you given sufficient information, I still would have recommended using a 12V fan just for safety reasons- no live 110V wires inside the chamber to possibly kill you. You don't even need to put an outlet on the controller box, just plugging it in the wall will work, provided your house wasn't a DIY project, too.

If I thought you understood how to communicate the minimum details needed to provide any advice, much less take heed of any that I take the time to provide, I might have been inclined. Just take a look at the fan discourse-

Me: Use an always on 12V case fan and cell phone charger.
You: But I already have a 110V fan (no type).
Me: Computer fans are cheap, even free.
You: I don't want to bother with a 'whole nother' outlet. (no reason given)
Me: running the fan all the time provides the most benefits
You: I could just leave the fan off. Is there any benefit?
Porc:A fan is of benefit in a chest freezers.
You: So, it's not worth it to run a fan in a kegerator? (No description/type)

I didn't even include your first post which essentially amounted to "I have some black wires, and I wired some of them together, and now it no work. Oh, and, it makes some noise that I no like."

Porc was essentially repeating what I posted in my initial and subsequent posts. Had you asked the same question 3 more times now that he answered your question twice (at least), even he might have gotten a bit frustrated.

I provided the most crucial advice, which was to unplug the device as soon as possible. The only assumption I got wrong was the size of your fan. My initial diagnosis was correct even though it was based off assumptions from the limited information you (continually) provided. I only got short after it became apparent you don't read thoroughly, don't provide enough information, assume others should intuit your situation, and don't heed advice well.

The information you are now seeking really isn't related to this thread. Try looking for threads about fans.
