We have the same "low air" problem on the GE Dryer as Newbie288. It was installed about a year ago and has had the problem since the beginning. I had the local appliance repairman look at it and he called in to some appliance repair place to get help. He claims that the dryer vent is facing west and getting too much wind causing the vent to cool down, especially in the winter (we live in Montana), and the stupid low air monitor says the exhaust is not hot enough and we stand the chance of the moisture condensing from the cold air and slowing the exhaust of the dryer. Well, it's been 98 degrees here the last few days, and the dryer still exhibits the "low air" warning on every full load of towels on high heat. I had the exhaust pipe blown out and nothing changed. But, it almost always fails (low air) on heavy towels and the towel cycle. I've never had it happen on delicate or other cycles. I agree that "some screwy feature was added to an electronic board and Some electronic engineer somewhere had to justify their existence and made up this feature." If someone has solved this problem, I'd be forever thankful for your advice.
PS We have essentially a built in dryer, hard to access the electric plug in the back, and have to go down 22 stairs to the basement to switch the circuit breaker to reset the dryer. It doesn't go to high heat when the low air light is on.
