Is the fan broken or is it merely dust?
My fan has recently stopped working. No more air passes through the vent.
The fan hasn't been cleaned. Ever. It's caked with dust. And I do plan on cleaning it, but I first have a question.
How do I tell whether the fan isn't working because of dust or whether it's just completely broken.
There's a high pitched straining sound coming from the fan during use, and it heats up very quickly.
