I found the issue with my dryer...works normally now. I blew out and vacuumed the exhaust vent. Used a blower to blow out and a shop vacuum to remove as much lent as possible. Had a blockage that caused the dryer temperature limit safety switch to cut power to the heater after the temperature reached a certain point. The drum continued to rotate on my Whirlpool Model # GEW9250PWI. The laundry would mostly dry, but now dries like new. I have a 32' vent. Will swap it out to a rigged vent because of the long distance and one 90 degree bend. 40' is the max with rigid. Subtract 8' for each 90 degree bend. Also, subtract 8' for flex vent material. Current flex material is over the distance for best venting. Works fine now, but I will monitor to see if the issue returns. May need to change out the temperature limit safety switch if it has become weak.
