My 8-year old ML850 is starting to give me a problem where it reverses about half a second after it reaches the closed position. As it comes back up, the orange indicator light flashes 11 times which is a bit confusing as the diagnostic codes only go up to 6!
If I reset the travel limits & force, it'll behave itself for another couple of opens but then revert to opening as soon as it hits the bottom. Checked all the usual stuff, no debris, safety beam isn't being broken, no binding on guides etc. Have tried powering off the unit to reset it, then resetting travel limits & force but the problem still remains.
May just be coincidence, but it's happened just at the start of this very cold snap we're having.
Is it likely the logic board needs replacing?
Cheers,
Dan
