Yep, I hope it is a fluke too. I'm actually bidding on another speed controller on eBay. I'm generally like @JRHAWK9 and have two of everything but for some reason I didn't have a backup speed controller. I listened to the furnace go off and on a couple times and thought it was really a step backwards in functionality. Of course my speed controller has to die right before the polar vortex is ready to hit.
Probably a fluke, mine have been rock solid but a back up is a good idea. Course we're all buying these off EBay, with an unknown history, some of these could be factory rejects, returns or what have you, who knows?
