hello all, im entering my 3rd year of using my harman p61a and it seems like my dial settings aren't calibrated like they have been in past years. for instance, i had the stove set at room temp @ ~67deg but the room was 80. Also, i tried to turn my distribution fan speed to low (dial goes off > L > H) and i had to put it down between off > L for it to actually turn the fan down to low. it's teetering between of and the beginning of the L > H brackets. I think i still have some warranty left but i was wondering what the forum thought could cause this of if i'm actually just not remembering correctly how it worked last year.
