Garage door wall unit appears to lock on its own

I have a Marantec 260 garage door opener with an associated Marantec wall control unit. We bought this new house in 2018 and about a month ago the garage door started vacation locking on its own. I think it began when early in the morning when I pressed the lock button by accident, and it appeared to happen from there. I thought it might be the wall control unit or a sticky button and I ordered a new wall unit, and replaced it. It seemed to work for about a day just great and then the same behavior.

You can open the door and the vacation lock turns off(the flashing light stops). Then you walk out to look at it later and the light is flashing on the open button again indicating it's locked. And sure enough, the remotes do not work on the door.

After changing the wall unit, I'm at a loss at this point. Any advice?

Sorry not familiar with Marantec's... maybe there is something in the manual. If I had to guess I would say circuit board is faulty.Marantec Comfort 260 Operating Instructions Manual

I'm having the exact same problem with a Marantec 4700 that is about 10 years old. Like you, I tried replacing the wall mount controls, but no luck. I also tried swapping out the remote control for the outside, and also the remote control receiver (the little thing with a wire antenna hanging off it), but neither helped.

The vacation lock button sometimes will turn off the vacation lock, but it often takes a few tries, or you have to run the door up or down first. But even then, after the lock is off, the next time you run the door, the vacation button starts flashing and the lock is back on. I've tried re-setting the operator, but that does not seem to help either.

The 7 button is also flashing, which I believe is the error for the "adjustments setup being interrupted before completion," but I've tried running through setup again, no change.

The other weird thing is that when the lock is on, you can still open the door by pressing the wall control door button 3-4 times.

For me, it started after we returned from a trip. There was a big electrical storm while we were gone, so I wonder if it damaged the operator. But it seems to work fine, other than this glitch with the vacation lock.

I have recently discovered the exact same problem with my Anytime Garage Door A370, which I am nearly certain is the same thing as the Marantec Synergy 370. What I have also observed is that the unwanted lock mode we are talking about is automatically entered at the same time as the operator light automatically turns off following a closing of the door with the remote control. This can be verified by changing the duration of that light being on following closing of the door with the remote control. All this is obviously a bug or malfunction in either the the hardware and/or firmware of the operator. I am going to try doing a hard reset of the operator to see if that fixes the problem, but I read here that someone else has already tried this. If this works, or if I learn anything else, I will report back. In the meantime, has anyone else discovered a fix for this?

Is there a way to reset the system to factory settings? Might be worth a try.

I'm reading lifetime warranty. Then limited lifetime warranty. Then 8 year warranty on parts but not labor. If you need a part under the 8 year warranty it must be sent to authorized dealer.

That pretty much says it all.
Has anyone contacted Marantec directly on this problem ?

For starters, I went through the reset procedure described in the manual, but it did not fix anything. This squares with the experience reported by Vauban on 8/21/2021, above. Next, I managed to talk to a product manager at Marantec who claimed to have never heard of this issue. Perhaps. What he indicated was that it was being caused by one of two things: Either: a) A faulty wall-mounted control switch. This could be tested by removing the electrical connection of that switch from the operator. The simplest way to do this is to disconnect power from the operator, remove the wires connected to Terminals 3 and 4 from the operator, then restore power, and test. (You remove and re-insert the wires by pushing in on the plastic tabs pretty hard with a screwdriver, as this opens up the contacts.) I did this and it had no effect. Notice from my prior post that you might have to wait about 5 minutes for the problem to show up again after power is restored - it can take up to that much time for the vacation lock mode to become enabled after a power cycle. b) Replace the control/logic box inside the operator. You can presumably have a registered Marantec dealer do this for you. But I have decided to try the repair myself. (I am an electrical engineer, but even without that it looks easy.) For the Synergy 370, the Marantec part number is 116422. (There is also a #116421 for 200-series openers.) I had trouble finding someone who would sell me the part, but I finally have one ordered from North Shore Commercial Door. It is scheduled to arrive tomorrow, and I have high hopes that it will work.

Regarding my post yesterday, I can happily report that replacing the control/logic box with Marantec part number 116422 for the Synergy 370 fixed the problem. Of course there is no guarantee that the same problem will not crop up in this new controller somewhere down the road. But for now my garage door opener is working again, i.e., it is no longer entering vacation lock mode on its own, and getting stuck there.

Regarding the replacement procedure, it went smoothly, although it took some care and experience pulling off and replacing the two sets of thicker wires. (I believe these are the ones that connect to the motor and the power supply.) Then after restoring power you have to go through Section 11 of the manual, labeled Initial System Setup. Be sure that the garage door is down before starting the replacement, as it seems the door has to be down when power is re-applied for the instructions in Section 11 to work.
