Broan Model 1052, stainless, built in

One day I found the compactor running continuously. Turned it off, door won't open, ram in down position, won't raise.

I removed the compactor's rear access plate, raised the ram using socket wrench, reattached chain, reassembled unit. Very next cycle chain falls off again.

This time I ran the unit with the back access plate removed. At the point the ram is at the lowest position, right before it reverses direction, the chain begins to rattle heavily to the point of it getting jambed around the larger sprocket teeth and is forced off.

The manual suggests this is caused by flying trash, which is not the case, that chain looseness is normal, and to inspect for any loose nuts/bolts.

This is a new compactor, hasn't even filled the first bag yet. I notice the upper sprocket, the smaller drive one, is on one assembly and the lower larger sprocket is on another assembly mount. The upper assembly moves independently of the lower one, and when the ram is compacting at the lowest point, the upper assembly begins bouncing around which causes the chain to wobble and eventually detach itself from the large sprocket.

I checked for loose bolts/nuts, none, except for the design of the upper assembly which is meant to be loose, to pivot as the ram lowers.

I removed the half-filled trash bag and replaced with new bag. Chain now stays on, but will come off again when trash is added, when the ram has to actually compact.

I'd like to fix this myself if possible rather than having a tech come out. No way to tighten chain, no way to stabilize upper assembly, no way to remove link in chain, and I even tried to add a "chain guide" in the area.


help ?
