I have the non-digital temperature control where you need to turn the dial to the left for cold and right for hot. Today when turning it towards the right from cold to hot it seemed a bit stiff and seems like some sort of resistance as it goes through the motion. Anyone else experienced this? I left it on cold in cold weather with the fan off so wondering if material expansion and contraction was the cause? Will leave it on hot tomorrow and see if it makes a difference
