I had two of these do this to me about a year ago... within the same week. Haven't seen another since. Anyway, what I found was that if you look closely at the inverter assy, specifically the gate you speak of, you will find two small pads on the frame that the gate rests on. What happens, in my case anyway, the pads wear down and tear. This exposes the adhesive from underneath the pads, causing the gate to stick after setting awhile.
When you first show up to work on the machine, reach your hand in there and see if you can move the gate. If you feel a slight bind, then feel it give way, then you know this is your problem. After it's released from the pads, it has to sit awhile before it will stick again.
My suggestion... Tear down to the inverter assy and remove the small black pads and clean the frame, where the pads were located, making sure there is no adhesive there. This should solve your problem.
