I replaced the hinges/springs in my oven door last year because the door would not shut properly. Now I’m having the same problem but I hate to buy more hinges as i don’t have confidence that it will fix the problems. As far as I can tell its the only mechanism for keeping the door shut so maybe them the hinges are a poor quality oem part. Any suggestions?
Here is an operators manual.

Sometimes just removing then reinstalling the door will fix this (see the manual).
If that does not fix it I guess it needs another set of hinges.
AppliancePartsPros only shows hinges made by Whirlpool but I cannot comment on their quality.
