When I bought the Compact, the blowers didn't blow any air at all - although there was some heat. I replaced the FSR with a new "quality" item off eBay. I turn the dial to 1, there's a little air. Turn to 2, there's an increased flow of air. There's no difference between 2, 3 and 4 however.
Is this likely to be a duff FSR or am I to check something else? I know there's a whole lot of info on FSR's but I don't see many posts describing the issue I'm having.
