I have installed several fans, none like this one. Hampton bay- Item # 249-872 , Model # VFB25ACLED1-5
I want to turn on the fan and light at the same time using one switch. I have 12-2 wire to the fan box. one black , one white and ground. The fan box has seven (7) wires, Black- ( L) , White- (N), Gr.- Ground, Blue- Light, Brown-Fan,
Red- n light, and yellow- common.
The installation instructions are totally inadquate. I had a electrian look at the wiring diagram, he said it was confusing.
I have tried several combinations, light works, but the fan does not, one of the many combinations the fan worked for about 45 sec. then stopped. breaker was not tripped.
How can this fan be wired to turn both fan and light on at the same time? What is the yellow common wire for?
This is very helpful. Can you tell me how to reuse the quick connectors for the wiring on this same unit? The manual says they are reusable, but i tried the tabs and can't seem to get them to release.
Thanks, in adance.
DON'T BUY THIS PRODUCT TO REPLACE AN EXISTING UNIT!!! I've never been so frustrated and disappointed with a Home Depot product. First, the cut-out dimensions are wrong, resulting in a hole equal to the size of the mounting flanges rather than the housing w/o the flanges. Second, nowhere on or in the box does it say that this unit requires a 120v power supply, but low voltage (DC) switching. Even the wiring diagram fails to mention the low voltage switching, which likely explains why the things fail after someone connects this to 120v switching. So, I've paid a premium price, spent 90 minutes in a hot attic, cut a hole too large, and can't use my existing wiring to complete the installation. Returning the product is a less than satisfying solution.
I am having the same frustration with this unit as 911_in_SC and mmmmFoundation. 12-3 coming from two switches that controlled a pre-existing light and fan (not HB model) separately. Now, I have 4 wires trying to feed this 7 wire unit. We won't be using the night light either. There has got to be a quick way to hook this up. I have tried the combinations that seemed logical, but with ac/dc, what is the answer please?
Hello Barefootn. Welcome to the Community!
Without a schematic I can't tell you what the 24 volt DC side is referenced to. In most, but not all cases you should be able to use the chassis as the eventual ground for the DC circuit, When you measure the voltage though even with a working unit the potential DC difference may not be 24V at the chassis though. There should be some voltage potential between the Yellow DC power out and the chassis ground however, and this could be one way to find out if the power supply is working or not.
In any case I think this is a moot point. If you know that there is AC line voltage into the unit and it has been properly wired then the simple fact is that this unit does not work. Even if you mixed up the low voltage wiring at least one of the 3 operations would run when switched on. Yes, given that none of the 3 DC circuits operate it sounds like the power supply inverter is defective since the odds of both lights and a fan motor being bad in the same unit are astronomical. Rather than troubleshoot I would just exchange it for one that has not been opened.
I just purchased 2 of these fans as replacements. I installed the first one using low voltage sprinkler wire and a Cooper 3-function rocker switch. Nothing works. I've verified I have line voltage to the unit, the low voltage wiring is intact, the switch is functioning. One thing about this unit is the box was opened, but it didn't look like it had been installed. How do I troubleshoot this thing? I've tried measuring the common lead for 24v, but what is the other side of the circuit?
Thanks Chris! Execllant Reply.......
We (the wife and I)had discussed a mechanical spring loaded count-down timer for the fan connection - not our favorate, but.... As stated we already bought the unit - and have the USE AND CARE GUIDE hardcopy. I'm embarrsed to admit I missed the note about solid-state control devices. Thanks for being there with the answers....
