Question about Building Materials
I have a mater mechanic 601mm garage door opener. Right now the unit appears to have lost its settings. I cannot get it to stop going down or up unless I stop it myself. Its gone crazy and I cannot use the settings for travel to stop it either.

I'm no expert, but on a previous door opener I had (don't know the brand), the side adjusting screw basically adjusted a limit switch, which was located inside the plastic housing (where the motor is). I was able to remove the housing, figure out which limit switch was actually being contacted "too soon" on the way down and adjusted it while watching it.
Just a suggestion, you might take a look.
just keep your hands out of the way of the chain and sprocket if you do take the housing off. .

SOURCE: Hello, I replaced a worn out
Yes, reread the directions travel needs to be set for both up and down, and MUCH MORE IMPORTANTLY the safety settings must be set. This allows the door to close on a foot and not cause damage....VERY IMPORTANT to set correctly....
