Our slow cooker/crock pot lid handle broke today, but I found a tutorial for the exact problem fix and managed to repair it.
I'm not sure how the rubber o-rings I used will hold up over time, will have to see, since I didn't have a washer similar to the original one that was glued/caked up in place on the old bolt/nut on the lid.
*Edit: Ma had some spare washers in a container under the kitchen island sink, so I removed the o-ring I'd used for the repair and the better fitting washer was put in its place.
The only real concern now is how hot the exposed bolt/nut with the handle repair will get from heat transfer when the crock pot/slow cooker is in use, and will that mean someone is gonna get burned if not careful when grabbing the handle, resulting in hollering/cussing and a dropped and broken glass lid, lol.
I suppose there might be a rust issue with the nut/bolt over time, but maybe that'll just be a potential little bit of iron oxide spice added to the diet...
