Maytag Neptune gas dryer all of a sudden is reading 85 minutes to dry on sensor setting. It did read approx. 45 to 50 minutes. Seems it may not getting hot enough. When start I can hear a click noise then about 1 minute later it does it again. Does this a few times. On wrinkle release it gets hot. Any ideas on where to start. I am an auto mechanic by trade and have real good diag skills. Any help to point in right direction would help.
