Motorlift ML850 Reverses on close. LED flashes 11 (!) times.

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

Hi,

After 8 years of use, you may find that the white cogs inside the unit are worn and may need replacing. This is usually the symptom shown when the cogs are worn out. You will require taking the cover of the motor and inspecting the cogs.

The replacement parts can be found at the link below.

Cheers Sav, I'll have a look at it this weekend and report back. Anything to watch for when removing the cover or is it pretty straightforward?
