Dale,
Who needs a frig when it's -9? I am sorry I should not have said that when I am parked in Florida! Hope you have a sense of humor.
Okay, now I don't have a coach exactly like yours, but I do have a degree in electrical engineering - ha ha And, I slept in a Newell last night...
So, my suggestion would be to temporarily disconnect from power and remove the cover on your transfer switch. You should see two black cubes right up against each other. When they are working correctly, only one is energized. They are probably both mechanically and electrically interlocked in an effort to be sure both can never be closed at the same time. In the center of each there should be a small rectangular projection that is connected to the portion of the contactor that moves when it is energized and de-energized. At this point they should both be de-energized of course and both protruding upward from their case. If you have some spray lube that is safe for plastic you could try some of that and then work the buttons back and forth to see if you can free things up. If you try to push both down at the same time they should resist. But, if you ease pressure on one it should allow the other to be pushed all the way down. Working them back and forth may do the trick. Again, be sure there is no power on the coach when you do this. If you feel comfortable with a voltmeter you can leave the cover off and energize the coach. This will allow you to check the voltage on each terminal and visually see the contactor is fully energized. Russ
