Re: old belling. who has these hinges for top oven
If the hinges are not broken but are not pulling the door shut tight, it is possible to correct the problem.
Strip the door and release the springs to the hinge carriage (the part with the rollers on it). With a rat- tail file, file the slot in the frame upwards about 5-6 mm on the inner and outer part of the frame keeping it the same dimension all the way. Test by pushing the hinge up to check the rollers don’t bind at any point in the slot. Repeat for the other hinge on the other side of the frame. When the springs are refitted, the hinge tangs should be leaning towards the top of the door. Refit the door to test: file slots more if required. Grease the slots and reassemble. Refit the door.
Easy enough job to do; I did quite a few like this in the past, all worked OK. 8)
