Absolute beginner requesting help identifying component

tebbybabes:
Hello, my name is Steven and I've just come across your forum. Took the chance to register so I might get the chance to further my knowledge.  :)

Quick backstory is I have a ceiling fan that is slower than molasses and I at least know enough that it's most likely a capacitor problem.  The fan company says that the problem is an easy fix and that I just need to replace the controller module and it will be right as rain.  Trouble is, the electronic module, while user replaceable, is also $100, while the fan itself is just $200.  I figured I would try to have a look at it and maybe learn something new. 

Which takes me to my current query.

I was hoping I could ask help in identifying this particular component in the photo.  It's the one that looks like dumbells?  I know the big yellow ones are capacitors and I thought they would be the one needing the replacing, but these ones look a bit dogdy.

Thanks in advance and if I'm barking up the wrong tree, apologies.

xrunner:
They are inductors with a heat shrink over the windings. Usually labelled with an "L" such as you see on the PCB.

Ian.M:
.... and they look absolutely normal, with no signs of overheating or other issues.

tebbybabes:
Thanks heaps, folks.  That was even faster than I was hoping! 

and @xrunner, I have now noticed the "L" that you mentioned. Thanks.

In this case, I will now see if I can learn how to test capacitors to find out which one needs replacing.  Can't say that I'm super confident as the last time I soldered circuits was 30 years ago and I remember I did a piss-poor job of it.  :-DD

In the ceiling fan there should be another capacitor at the top, inside the canopy. That could be the most likely faulty part.
