My boss told me to just replace the whole door operator on a 90s Dover, but a guy at the supply house said to check the cam switches first.

It was a job in that old brick building on 4th Street. I was ready to order the whole new unit, but he said he'd seen that exact model get stuck because the cam switches just needed a clean and a small adjustment. Took me an hour, saved the building manager over two grand in parts. Anyone else run into those Dover cams giving a false 'door closed' signal?

My buddy had that exact thing happen at a warehouse last month. He spent twenty minutes cleaning the contacts instead of replacing the whole assembly.

That's the smart move, saves a ton of cash and hassle lol.

idk man, I mean cleaning contacts is great if they're just dirty, but sometimes the issue is actually pitting or wear on the contact surface itself. If you're just wiping crud off, it might work for a bit but you're still left with a compromised connection that'll fail again down the line. Maybe it's just me, but I'd rather spend the extra 10 minutes to actually replace the whole thing and not have to think about it again. That said, if your buddy's method got him through the shift without a callback, then hey, whatever works in a pinch.

My old foreman swore by checking those cams first.
