William,
Well, you will never believe it. It’s working again! For now …
I disassembled per a video I found on the internet. Everything went just fine. My actuators appear to be an older model. I took one apart. It was a PITA. It didn’t have a plug, it had a plastic case with clips. The motor came on (right side) when we flipped the breaker on. The left side did not extend normally, I was popping. I later found out this was because mine are adjustable and somehow the left was beyond the travel of the worm gear on the small motor. Because I disassembled the right one, I am not sure it was engaged or not. So I put the actuator back together and reinstalled both of them. The only thing I wasn’t sure about is to what height to adjust the arm that attached to the side lid carriers. So I guessed a bit and put everything back together. It didn’t work while apart, but when back together it worked normally. I ran a rise cycle to make sure the lid was closing tightly and everything functioned normally. I am assuming that the controller senses when the small motor amps start to change and determines full open or closed. I have no idea how the actuator screws backed out of the worm gear.
So here is my final questions. I now know the controller is all good. Should I proactively change the actuators (given their low cost) to ensure the same problem doesn’t resurface? Are the newer actuators adjustable or fixed? It looks like the new actuator will work on my machine, but the wires are soldered directly to the motor in my case? I would need a pigtail plug to connect to power in my case. Do the newer actuators come with that?
