How to Clear a Marantec Error Code
After fixing the underlying problem (clearing the doorway, realigning the photo eye, lubricating the door), press the wall button once to reset the display. The error code will disappear if the issue is resolved. If the code reappears immediately, the problem is not fixed — go back and recheck the specific cause for that code.
Codes 35 and 36 on all Marantec models indicate internal logic board failure. These cannot be fixed by adjustment — the control board needs replacement or professional service. Marantec parts are available through authorized dealers; a control board replacement costs $80–$150 for parts plus labor.
