Alpine XL - 15 Fan Stopped Working
Hello again, night light,
I don't think you hurt it by nudging the blades - I have one where it does the same thing unless I have it set on "max".
The challenge is that I don't know which is more likely the problem - I
haven't worked much with the electrical aspects of them recently - - I
might have to try working with one, although it may vary between models
- the one's on the circuit board would be harder to swap-out. What was
the vintage of yours again?
Good for you on having a multimeter, and being willing to learn to use
All I was talking about earlier was using the CONT (continuity)
function to check for a circuit (some models have a little buzz or beep
that sounds when you have a connection. If you have the fan pot. wide open, you should be able to get a good signal between the terminals of the pot.
Another option - crude, but effective - would be to "jumper" (short-circuit) the fan terminals (at the pot.) together to see if it runs with the pot. bypassed out of the circuit. This shouldn't harm the motor, and if it still doesn't work, that points to the motor being bad. As always, use common sense and be safety-concious, don't bypass the safety cut-out switch or the like.
I may have to check with one of my brothers (biomedical electronics tech.) for a little additional guidance - - he could probably give me better insight without spending a lot of time on trial-and-error. If that happens, I'll follow-up with another Solution entry in the next few days.
If I can be of further assistance, or if you have additional questions/comments for this item, please let me know.
If/when this solves the issue to your satisfaction, please rate it accordingly.
Thanks in-advance for using Fixya.com,
