I have a front load Sears Kenmore washer.
The door sometime wouldn't close until you pushed it closed.
Now it doesn't close, just buzzes.
It doesn't look like there is a catch broken or anything.
Any ideas?

Check to see if there is something back by the hinges

Chucktstevens - Check to see if the hinges are bent or sprung, or the door is out of adjustement.The catch may be broke off now is why it won't stay closed ,check to see if the door catch is still there , It will buzz because of the door not being clossed the door switch does that , Good luck and have a good day , Yopu may have to call sears repairman .
