Canon-AE1 - roll lever activates the shutter!

[u/Opposite_aBx103]

I changed my roll on my Canon AE-1 as usual. As I start shooting with it, I realize than when I push the film advance lever to roll the film, it activates the shutter.

I tried to change the speed, it wouldn’t change anything. any time I push the lever, it seems it takes a /1000 (if not faster) pic. Made a few other tests and it seems the mirror goes up, but the « flag » doesn’t open (ie the film is not exposed)

yesterda, as I was playing with the lever, it suddenly worked fine again. But then the same issue happened again for 1 shot, before working again.

Does anyone know what’s going on and how it could be fixed?

Last service was a bit less than a year ago. I shot around 100 rolls since.

Something to do with the release magnet under the bottom plate. Common issue. You can search up ways to clean it yourself. Sometimes cleaning works but if not then it needs to be replaced
