Cleaning my 10 year old Harman today and noticed some ash residue around the door frame on the latch side. Not a lot, just a faint trace but it’s new. The frame appears to have two special screws on either side, not Phillips or straight, can’t remember the name. Anyway I’m sure there’s a seal under it and wondered if trying to tighten them would help or is this a service issue. I’m 78 and 180 rt from dealer
Thanks in advance
