If that door was a computer, I’d say “Buy a power filter”. For a computer, that’s about $30- probably adding a power filter to your do would cost $1000 😉
Its funny to me, though, that a device can work perfectly so long as its running. As soon as you stop it and try to start it back up again, though, you reveal all its weaknesses. Its the old “starting/stopping is where all the wear and tear comes from” theory.
