Preventive Maintenance Auto Transfer Switch
Is there any preventive maintenance we should be doing on our Auto Transfer Switch? Heres why I ask - We just had an odd situation. Plugged into shore power a couple days ago as normal, then flipped...

If your 07 is like my 08, the IOTA transfer switch has been recalled by NTSA. The terminals loosen up over time and act just as you describe plus they can overheat to the point of causing a fire.
Info ....
The transfer switch is rated to function with heavy loads (such as air conditioner) being active when engaged if you have auto temp start for the generator. Many of us have animals and keep the temp start active when there's a chance of hot weather driving up inside temps.
When my transfer switch first acted up, the control panel lights would come on one at a time as you say, then shut off and restart. It was the transfer switch kicking out from a damaged (loose and overheated) terminal on L2.
You can tighten the terminals inside the transfer switch and it will work again for a while, if it's not already damaged like mine was. But the condition usually returns, ... best to replace it.
Don't these idiot manufacturers know what a SEMS SCREW IS?
With really critical tab connections I use a longer SEMS screw to bind the wire terminal to the threaded tab then use a KEPS NUT on the other side, I freakin' guarantee you that termination will not "loosen up" EVER.
