I got a second ashpan for my Mag this year. My setup is plugged into an outlet on a switch, so All I do is outen the switch and let her cool for a few minutes, then flip-flop the ashpans and hit the switch again. Also turn off when I do my weekly fly-ash clean-out and then on when done, never had a problem.
Got the second pan idea from this forum, so thanks again fellas!
