Trying to smoke some ribs by time. Set temp to 225 but unit does not climb above 175-180. Made sure probe was not on anything and noticed the temp dropped when I lifted the probe slightly. Finally removed Auber and am cooking by the dial which turned off burner when I dropped the dial to 220. I took the Auber inside and put the probe in the oven at 220 degrees. Probe works fine in there and was actually reading higher not lower. Any thoughts?
